The PERC 2 RAID controller contains four channels. PERC 2/Si and PERC 3/Si are single integrated channel controllers. The PERC 3/Di is a dual integrated channel controller.
Working with these controllers requires an understanding of the Array Manager storage model, which represents the Array Manager storage objects in an object hierarchy. Each object has a set of attributes and operations associated with it. Attributes describe the properties of the object, and operations allow you to create new objects and modify existing object attributes. See The Array Manager Storage Model section in the Storage Management Concepts chapter for more information about the Array Manager storage model.
Unless otherwise stated, each operation described in this chapter is available on each controller type listed above. Operations that are inactive (dimmed) in the console are not supported or not available at that time. To view attributes or to perform operations, right-click a given storage object. A context menu will appear with a list of commands available, including a Properties command.
Array Manager allows you to create virtual disks, which are logical disks that can be created from one or more physical disks (known as array disks). The logical disks can have RAID layouts, which let you to manage your storage more efficiently. Once a virtual disk is created and a rescan is done, the Windows® operating system sees the virtual disk as if it were a physical disk. The topics in this section include:
Creating virtual disks is the first step in configuring your RAID storage subsystem. For more information about creating RAID solutions, see Choosing RAID Levels in the Storage Management Concepts chapter.
Right-click an array group and click Create Virtual Disk.
Read the welcome screen shown and click Next to continue. (You can cancel the operation at any time by clicking the Cancel button.)
The Select Creation Mode dialog box appears. Select Express or CustomMode and click Next to continue or Back to return to the previous screen.
ExpressMode examines your current physical disk layout and available space, and then calculates an appropriate virtual disk layout for you. You select the RAID type and size.
CustomMode allows for a more detailed configuration of your choice. You select the array disks to use.
Click Finish to create a virtual disk or Back to return to the previous screen.
On Windows NT, Array Manager displays a Rescan Disk Layout check box on the
last panel of the Create Virtual Disk wizard. When the Rescan Disk Layout check box
is selected, Array Manager automatically performs a rescan. A rescan may be
necessary for the new virtual disk to be displayed under the Disks object in the tree
view. If the Rescan Disk Layout check box is not selected when you create the virtual
disk, you can perform a rescan at a later time by using the Rescan command.
Each virtual disk is automatically mapped to a Microsoft Windows NT or Windows
2000 disk. For example, if Virtual disk 0 is mapped to NT/2000 Disk 0, the Array
Manager console will display Virtual disk 0 as "Virtual Disk 0 (Disk 0)," and NT/2000
disk 0 as "Disk 0 (Virtual Disk 0)."
If a virtual disk is not mapped to an NT/2000 disk, please reboot the system.
If necessary, add a disk signature to the virtual disk.
If the new virtual disk has an error icon and the General tab view shows that the disk
has no disk signature, you will need to add a signature to the disk. For instructions on
writing a disk signature, see the section Write a Disk Signature in the Disk
Management chapter. For Windows 2000, a disk signature must be added manually.
For Windows NT, the signature is added automatically.
Use the Virtual Disk Reconfiguration wizard to change attributes of a virtual disk on a PERC 2, PERC 2/Si, PERC 3/Si, or PERC 3/Di controller. You can:
Migrate from one RAID type to another without adding space.
Use this operation to assign and configure a dedicated hot spare. This hot spare will be used to rebuild a degraded array disk, if possible.
If an array disk belonging to a virtual disk fails or is removed, the virtual disk will become degraded. A degraded virtual disk that has a properly configured hot spare will automatically rebuild onto that hot spare.
Note This operation is highly recommended for redundant RAID types such as RAID-1,
RAID-5, RAID-1 Concatenated, and RAID-10.
Right-click a redundant virtual disk and click Configure Dedicated Hot Spare.
Assign the disk or disks you want to configure as hot spares by highlighting the disk in the left panel and clicking the Add Disk>> button to move the disk to the right panel of the Virtual Disk Dedicated Hot Spare Configuration dialog box.
Click OK.
Note Hot spares for PERC 2, PERC 2/Si, PERC 3/Si, and PERC 3/Di controllers are
always associated with a specific virtual disk. These controllers do not have a global
hot spare option.
Use this procedure to format a virtual disk on a PERC 2, PERC 2/Si, PERC 3/Si, or PERC 3/Di controller. This operation erases the files and removes the file systems on virtual disks but keeps the virtual disk configuration intact.
Note If you are formatting a virtual disk on a NetWare® system, you must first go to the
NetWare console and remove the corresponding volume and partition. For
information on how to perform these operations, see the appropriate NetWare
documentation.
Note If you format a virtual disk that has been upgraded to dynamic, the disk functions
may become inactive or the status of the disk may change to "foreign" or "offline."
You can view a disk's status by selecting the disk's General tab. When using a PERC
2, 2/Si, 3/Si, and 3/Di controller, you can resolve these problems by doing a global
rescan.
This command recovers the disk space occupied by an orphan or dead disk segment. An orphan disk segment is part of a multipartition virtual disk that cannot access another disk segment within the same virtual disk. A dead disk segment is either no longer needed by the virtual disk or is physically damaged. This operation can be performed only on failed virtual disks of redundant RAID types.
Use the SplitMirror command to permanently convert a mirror set or a multilevel virtual disk of mirror sets into two concatenated sets or two multilevel virtual disks of concatenated sets and preserve the data in each resulting virtual disk.
Note This operation is not supported in NetWare. It is also not supported when using a
dynamic virtual disk with a PERC 2, PERC 2/Si, PERC 3/Si, or PERC 3/Di
controller.
Use the Unmirror command to convert the mirror set to a concatenated set or convert a multi-level virtual disk of mirror sets to a multilevel virtual disk of concatenated sets. Unmirroring preserves the data in the mirror set or multilevel virtual disk of mirror sets, but erases any data maintained by the redundant segment and returns the redundant virtual disk's segments to free space.
The Blink Virtual Disk command allows you to locate the array disks included in a virtual disk by blinking the light-emitting diodes (LEDs) on the array disks. This command will automatically cancel in 30 seconds.
Note A right-click any one of the array disks displays a menu of supported operations.
These menus are dynamic. Not all menu options are available at all times.
The Initialize command prepares an array disk for use as a member of a virtual disk. For details, see the Initialize Array Disks topic under the General Controller Commands section later in this chapter.
Caution This is a data-destructive command. Any virtual disks residing on this array
disk will be removed.
This command removes the disk space occupied by an orphan or dead disk segment.
A segment may be designated as dead if it is logically bad, is physically damaged, or resides on a disk that has been disconnected from and then reconnected to the controller.
The Blink command allows you to find an array disk within an enclosure by blinking one of the light-emitting diodes (LEDs) on the disk. This command will automatically cancel in 30 seconds. You may wish to use this command to locate an array disk that has failed.
Click Prepare to Remove, then click Yes to continue.
When the lights on the disk you have prepared to remove stop blinking, the disk is ready to be physically removed.
The disk that you have prepared to remove will not be displayed in the Array
Manager tree view. After you have replaced this disk and performed a rescan, it is
displayed once again in the tree view.
Use this command to display the array disk properties.
Note Array disks for the PERC 2, PERC 2/Si, PERC 3/Si, and PERC 3/Di controllers
display Ready status regardless of whether they are a part of a virtual disk or not.
Ready status means the disk is operational.
The Rescan operation scans the channels of the controller to verify the currently connected devices or to recognize new devices that have been added to the channels.
After the operation is finished, the console is refreshed and any configuration changes appear under the Array Group object and under the channel object.
The removal of an array disk within a virtual disk is reflected immediately in the console, whereas an addition is reflected only by performing the Rescan operation. Array disks that are not part of virtual disks will not be polled for status changes.
This command pauses I/O on all channels that are polled for status changes on the controller. Use the Pause I/O command when you need to hot-swap disk drives without having to reboot.
If the disks are contained in an enclosure that supports hot-swapping, Pause I/O is not required unless the disk is part of a virtual disk.
Caution This can be a potentially dangerous command, and sufficient steps should be
taken to warn others who may be using any virtual disks on the selected
controller that I/O will be paused.
This command extracts a log from the controller(s) and places it in the Array Manager installation directory. When you export the log file from the controller, the controller's event information is cleared. The log gives detailed information on the controller activities and can be useful for troubleshooting. The log's file name is the word "log" and the month and day, such as "log0921" or "log_0921" for a log created on September 21.
Use this function to display controller attributes.
Right-click a controller.
Click Properties.
Properties for each of PERC 2, PERC 2/Si, PERC 3/Si, and PERC 3/Di controllers appear differently. When a controller is opened in read-only mode, the console displays Read only in the name that appears in the left pane. If the controller is already in use, it can be opened only in read-only mode.
Note A controller will be opened in Read Only mode if it is already in use.
Note The PERC 2/Si and PERC 3/Si RAID controllers do not contain a battery and
therefore do not support battery management.
The battery of the PERC 2 controller preserves the contents of its nonvolatile cache memory in the event of power loss. The battery provides a minimum of 72 hours protection for DIMMs up to 64 MB and 48 hours protection for 128-MB DIMMs. However, the duration of protection, or holdover time, depends on the battery's charge level. This section has two topics:
The battery is fully discharged when you first install the controller. The controller detects this condition and automatically begins charging the battery. This charging process takes approximately three hours. The controller can be used during this time; however, the battery is unable to meet the specified holdover time until it is fully charged. The battery is still able to handle brief power losses during the initial charge cycle.
After you have installed the controller, it notifies you every six months that a battery reconditioning cycle is required. This reconditioning cycle requires a full discharge and recharge of the battery. It ensures that the battery's capacity is being measured correctly and that the battery's full holdover time is maintained.
The reconditioning cycle takes approximately 8 to 10 hours. During this time, the battery's holdover time is reduced to zero (during discharge) and then restored (during full charge). To ensure that no data is lost from nonvolatile cache memory, the controller automatically disables cache (both read and write) during a reconditioning cycle. When the cache is disabled, performance is degraded for the reconditioning period. Once the reconditioning cycle is complete, the cache is restored to its original settings.
It is highly recommended that battery reconditioning be done during off-peak times.
Array Manager and FAST cannot both be installed on the same machine. If the Array Manager installation process detects that FAST is already installed, the Array Manager installation will not complete.
After some planning and preparation, it is possible to migrate array disks, virtual disks, and array volumes between one controller and another, between one enclosure and another, or between one server and another. You can perform array and volume migration on PERC 2, PERC 2/Si, PERC 3/Si, and PERC 3/Di controllers as long as the following conditions are met:
A virtual disk cannot be migrated from any PERC 2, PERC 2/Si, PERC 3/Si, or PERC 3/Di to any PERC 2/SC, 2/DC, 3/SC, 3/DCL, 3/DC, or 3/QC controller.
A virtual disk cannot be migrated from any PERC 2/SC, 2/DC, 3/SC, 3/DCL, 3/DC, and 3/QC controller.
To migrate virtual disks and volumes from one system to another, do the following.
Right-click the controller that contains the virtual disk(s) you are migrating and choose Pause I/O. You can also perform this operation with a shutdown of the server that contains the array disks and the virtual disk(s) that you wish to migrate.
Remove the array disks from the enclosure that belong to the virtual disk(s) you are migrating, making sure to remember their order.
Place the array disks into the new enclosure in the same order.
Click Rescan on the Array Manager toolbar.
The migration is complete. The virtual disk is now manageable via Array Manager.
The PERC 2, 2/Si, 3/Si, and 3/Di controllers support enclosure management. This section describes how enclosure management works and then details the specific enclosure management commands. The specific topics in the section are:
Array Manager enables management of various enclosures and their components. These enclosures include:
Dell PowerVault 200S
Dell PowerVault 201S
Dell PowerVault 210S
Dell PowerVault 211S
Dell PowerVault 220S
Dell PowerVault 221S
In addition to managing the array disks contained in the enclosure, you can monitor the status of the enclosure's fans, power supply, and temperature probes. You can view these components in the Array Manager tree view.
Array Manager displays the properties of the enclosure's fans, power supply, and temperature probes. Array Manager also notifies you of enclosure status changes through events that are displayed on the Events tab and logged in the Windows 2000 and Windows NT event log.
The following sections provide more information on the enclosure components managed by Array Manager:
When you expand the storage subsystem object in the Array Manager tree view, you see the controllers attached to the storage subsystem. The controller object expands to display the controller's channels. These channel objects are numbered in the Array Manager tree view to match the channel number that appears on the controller hardware. (See the controller's documentation for information on identifying the channels on the controller hardware.) For example, if the controller has two channels numbered 0 and 1, then the channel objects in the Array Manager tree view are named Channel 0 and Channel 1.
If the controller has a channel connected to an enclosure, then this connection is reflected in the channel name displayed in the tree view. For example, if Channel 1 is connected to an enclosure, then the channel object's name in the tree view is Enclosure (Channel 1).
Expanding the enclosure channel object displays the enclosure's fans, power supply, and temperature probes. Each of these objects expands to display the individual fans and so forth provided by the enclosure.
In the following graphic, the enclosure object is expanded to show the fans, power supplies, temperature probes, and array disks included in the enclosure. Because the enclosure is connected to channel 2 of the controller, the enclosure's default name is Enclosure (Channel 2).
For more information on the enclosure's components, commands, and the array disks included in the enclosure, see the following sections:
Enclosure management provides a feature which automatically shuts down the operating system, the server, and the enclosure when the enclosure's temperature reaches dangerous extremes. The temperature when shutdown occurs is determined by the enclosure temperature probe's Minimum Error Threshold and the Maximum Error Threshold. These thresholds are default settings that cannot be changed.
require that the Dell OpenManage Server Agent 4.0.0 or later be installed on the managed node in order to provide full thermal shutdown functionality. When the Server Agent is installed, the operating system shuts down and the server powers off when the enclosure reaches 0 degrees celsius or 50 degrees celsius. After the server powers off, the enclosure also powers off. If the Server Agent is not installed, then only the operating system shuts down when the enclosure reaches 0 degrees celsius or 50 degrees celsius.
For the Dell PowerVault 220S and Dell PowerVault 221S, the operating system and server shut down at 0 degrees celsius or 50 degrees celsius. These enclosures shut down when the temperature reaches 55 degrees celsius regardless of whether Array Manager is installed.
The enclosure's array disks are displayed under the enclosure object in the tree view. Selecting an array disk in the tree view displays the disk's status information in the right pane. For more information on the status information displayed in the right pane, see the The Right Pane section.
If you right-click an array disk in the tree view, the Array Disks context menu is displayed. See Array Disk Commands for details on these commands.
The fans that are installed in the enclosure are displayed under the Fans object in the tree view. You can select the Fans object to display the individual fans and their status information in the right pane. You can also expand the Fans object to display the individual fans in the left page.
If you right-click the Fans object or an individual fan, a context menu is displayed with a Properties option. For more information on fan properties, see Fan Properties.

You can select the Temperature Probes object to display the individual temperature probes and their status information in the right pane. The status information in the includes the current temperature in celsius and the warning and error thresholds for the temperature probe. The error threshold has a default value that cannot be changed. You can set the warning threshold, however. See Set Thresholds for Temperature for information on setting the warning threshold.
Right-clicking the temperature probes object in the left pane displays a context menu with a Properties option. You can also expand the temperature probe object to display the individual temperature probes in the tree view. Right-clicking an individual temperature probe also displays a context menu with a Properties option. This option enables you to set the minimum and maximum warning threshold for the temperature probe.
For information related to the enclosure's temperature, see the following:
This section describes the commands associated with the enclosure and its fans, power supplies, and temperature probes. For the commands associated with an enclosure's array disks, see Array Disk Commands.
Right-clicking an enclosure object in the tree view displays a context menu with the enclosure commands. Right-clicking the enclosure's fans, power supplies, and temperature probes also displays context menu for these components.
The commands on the enclosure's context menu can vary depending on the model of the enclosure. Enclosure context menu commands may include:
Rescan — Checks whether any new array disks and other components such as fans or temperature probes have been added to the enclosure.
Enable Alarm — Enables an audible alarm that sounds whenever the fault LED lights.
Disable Alarm — Turns off the audible alarm settings. If the alarm is already sounding, you can turn it off with this command.
Set Tag Data — Allows you to enter or change asset information for the enclosure.
Download Firmware — Allows you to download firmware to the enclosure.
Set Thresholds for Temperature — Sets the minimum and maximum values for the temperature warning threshold. This command is not located on the enclosure's context menu. It is located on the context menu for the individual temperature probes.
The context menu commands for fans, power supplies, and temperature are:
Temperature Properties — Displays temperature properties. To set the temperature threshold, expand the temperature probes object to display the individual temperature probes in the tree view. The properties for an individual temperature probe enable you to set the warning thresholds.

temperature probe as well as the default values in celsius for the minimum and
maximum error thresholds. The default values for the error thresholds indicate that
the enclosure has reached a dangerous temperature that may cause damage. These
default values cannot be changed.
Enter the desired value in celsius for the minimum and maximum warning thresholds in the Minimum Warning Threshold and the Maximum Warning Threshold fields. The warning thresholds indicate that the enclosure is approaching an unacceptably warm or cool temperature.
If you wish to apply your changes to all temperature probes in the enclosure, then
select the Apply these values to all temperature probes in the enclosure check box.
Click Apply and then Ok to make the changes. Click Cancel to exit the function without accepting the changes.
For information related to the enclosure's temperature, see the following:
This section describes procedures commonly used in association with enclosures. For additional information on enclosure commands and properties, see Enclosure Commands and Enclosure Properties.
Identifying the enclosure's service tag number — The command that enables you to view the enclosure's service tag number from Array Manager is the Set Tag Data command. See Set Tag Data for more information.
Preparing a hard drive for removal — The command that enables you to prepare a hard drive for removal is an array disk command. See Prepare to Remove for more information.
Troubleshooting — For general information on troubleshooting procedures, see Troubleshooting.
Removing the wrong drive — You can avoid removing the wrong drive by blinking the LED display of the drive you intend to remove. See Blink for more information. If you have already removed the wrong drive, see Recovering from Removing the Wrong Drive.
If you have not yet attached the enclosure to an open channel, you may need to identify a channel on the controller that can be used for this purpose. To identify an open channel:
Expand the Array Manager tree view until the controller object is expanded. When the controller object is expanded, the tree view displays the controller's channels. These channels are numbered starting from zero.
Identify a channel that is not attached to storage. When a controller's channel is attached to an enclosure or an array, the channel object can be expanded to display the disks included in the array or the enclosure. A channel object that cannot be expanded in the Array Manager tree view is an open channel not currently attached to storage. Array Manager displays a number for each channel. These numbers correspond to the channel numbers on the controller hardware. You can use these numbers to identify which open channel displayed in the tree view is the open channel on the controller hardware.
After adding a new hard drive or array disk, you may find that the hard drive is not visible in the Array Manager tree view. To make the new hard drive visible in the tree view:
Right-click the computer system object in the tree view.
You can view the current status of an enclosure and its components. To view status information, select the object for which you wish to see the status in the tree view. In the right pane, the Status field indicates the current status. The possible values are:
Ready — Indicates that the enclosure or its component is functioning normally.
Offline — Indicates that the enclosure or its component is not accessible. The enclosure or its component may be removed.
Failed — Indicates that the enclosure or its component has experienced a failure and is no longer functioning.
To check the enclosure's temperature, select a temperature probe object in the tree view. The temperature reported by the temperature probe is displayed in celsius in the Current Value field in the right pane.

When an individual temperature probe is selected, this field indicates that the enclosure component is a temperature probe.
Current Value — This field indicates the current temperature of the enclosure as reported by the temperature probe.
Minimum Error Threshold — This field displays the temperature currently set as the minimum error temperature. The minimum error temperature indicates that the enclosure has become so severely cooled that loss of data or other failure may occur. When this temperature is reached, the operating system that writes data to the enclosure automatically shuts down. This field cannot be modified.
Minimum Warning Threshold — This field displays the temperature currently set as the minimum warning temperature. The minimum warning temperature indicates that the enclosure is approaching an unacceptably cool temperature. Action should be taken to restore the enclosure to a normal temperature. Otherwise, data loss or other failure may occur.
Maximum Warning Threshold — This field displays the temperature currently set as the maximum warning temperature. The maximum warning temperature indicates that the enclosure is approaching an unacceptably warm temperature. Action should be taken to restore the enclosure to a normal temperature. Otherwise, data loss or other failure may occur.
Maximum Error Threshold — This field displays the temperature currently set as the maximum error temperature. The maximum error temperature indicates that the enclosure has become so overheated that loss of data or other failure may occur. When this temperature is reached, the operating system that writes data to the enclosure automatically shuts down. This field cannot be modified.
Apply these values to all temperature probes in this enclosure — When this check box is selected, Array Manager applies your changes to all temperature probes in the enclosure.
Reset Defaults — Click this button to reset the Minimum Warning Threshold and the Maximum Warning Threshold fields to their default values.
For information related to the enclosure's temperature, see the following:
The enclosure may contain one or more Enclosure Management Modules (EMMs). The EMM modules monitor components of the enclosure. These components include:
Fans
Power supplies
Temperature probes
The insertion or removal of a drive
The LEDs on the enclosure
When the enclosure's alarm is enabled, the EMM activates the alarm when certain conditions occur. For more information on enabling the alarm and the conditions that activate the alarm, see Enable Alarm. For more information on EMMs, see the enclosure hardware documentation.
The terminology used in the Array Manager console differs from the terminology used in the PERC 2 BIOS Container Configuration Utility (CCU). The following table shows a summary of these differences.
