This chapter describes Array Manager's remote connection capabilities. With Array Manager, you can connect to remote computers and manage their storage remotely.
In order to connect to a remote computer, you have to gain access to the computer by having an account that matches an administrator or supervisory account on that computer. The connection procedure for establishing your authentication varies depending on the type of remote computer you are connecting to. However, in all cases when you attempt to connect to a remote computer, the Connect to Computer dialog box will come up.
This dialog box allows you to identify the remote computer and gives you some options that make it more useful to connect to the computer in the future.
After you click the button in the Connect to Computer dialog box, you may get a second dialog box, the Remote Connection dialog box, which requires you to enter a user name and password and, when necessary, a domain.
Depending on the type of computer you want to connect to and, possibly, how you have logged in to the local computer, this dialog box may not always come up. Sometimes you will be connected directly to the remote computer without having to enter any authentication information. At other times, this dialog box will not come up and you will be denied access.
It is helpful to know that there are three different connection situations that are categorized by the type of remote computer:
NetWare® computer
Windows NT® 4.0 or Windows® 2000 computer with Array Manager installed
The simplest connection method is for a NetWare computer. When you attempt to connect to a NetWare computer, a Remote Connection dialog box will always come up to enable you to enter a user name and password. If you enter the user name and password for an account with administrator or supervisor rights on the remote computer, you will be able to connect.
The flow chart below diagrams the NetWare computer connection method:
If you are attempting to connect a Windows NT 4.0 or Windows 2000 computer with Array Manager installed, the initial login to the local computer determines whether or not you will receive the Remote Connection dialog box for entering authentication information.
The different ways you can log in initially on the local computer and their results when you attempt to connect to the remote computer are summarized as follows:
Initial login at the local computer
Result when you try to connect to remote computer
1
You log in at the local computer with an account that matches an administrator account on the remote computer. It can be a:
Local administrator account
Domain administrator account of the remote computer's domain or a trusted domain
You are connected directly to the computer without the Remote Connection dialog box.
2
You log in at the local computer with a local user or domain user account that matches a valid account on the remote computer that is NOT in the administrator group.
The Remote Connection dialog box comes up.
To connect successfully to the remote computer, you have to enter a user name and password that matches a valid administrator account on the remote computer. If you are entering a domain administrator account, you will need to indicate the name of the domain as well.
3
You log in at the local computer with an account that does NOT match any valid account on the remote computer.
The Remote Connection dialog box does not appear.
Access is denied per Windows security model.
In the third case in the table, you are denied access because your initial login does not show any relationship to the remote computer. The workaround for the third case in the table is to set up an account on the local computer that matches an administrator account on the remote computer and to log in to the local computer with that account. If the local or remote computer is in a workgroup, the third case probably will apply.
The flow chart that follows diagrams the possible connections for connecting to a Windows NT 4.0 or Windows 2000 computer with Array Manager installed:
Disk Management is the built-in disk and volume manager that comes with Windows 2000. Disk Management is also known as Logical Disk Manager, or LDM. Because Disk Management and Array Manager for Windows 2000 are related programs, you can connect to a Windows 2000 computer with Disk Management and manage its storage remotely from a computer with the Array Manager console software.
The situation for connecting to a remote Windows 2000 computer with Disk Management is fairly simple. You will never get the Remote Connection dialog box. Your authentication credentials are established at the initial login to the local computer. Thus, you must log in to the local computer with an account that matches an administrator account on the Windows 2000 remote computer with Disk Management.
The flow chart below diagrams the connection process:
Only a Windows 2000 machine with an Array Management console can connect to and manage a Windows 2000 server with Disk Management. If you are running Windows NT 4.0, you cannot connect to and manage a Windows 2000 server with Disk Management. The NT 4.0 Array Manager console does not have forward compatibility.
If you connect to a remote computer during an Array Manager session, disconnect from it, and then attempt to reconnect to it in the same session, Array Manager will automatically connect to it without a connection login box. The reason for this direct connection is that Array Manager keeps authentication information for all connections made during the current session. Thus, if you have already established your credentials for connecting to a computer in that session, you will not have to give them again.
If you attempt to connect to a remote computer that has the same administrator user name and password as another remote computer that you connected to in the current session, you will be automatically connected without a connection login box.
If in the current Array Manager session you establish a computer as a "favorite" and then disconnect from it, you can reconnect directly to it again in the current session by simply double-clicking its name in the Favorites list in the tree view. The same applies to a computer in the History list in the tree view. If you connected to a remote computer in the current session and disconnected from it, you can reconnect to it in the current session by double-clicking its name in the History list.
The question is often asked about a "favorite computer" that you have designated to be reconnected when Array Manager restarts. Will that computer come up automatically in the tree view or will you get a connection login box? It depends on your initial login to the local computer. In every case, Array Manager will attempt to connect to the remote computer. If your initial login establishes that you have administrator rights on the remote computer, the remote computer will appear in your tree view. However, if your initial login requires a connection login box to establish your credentials as an administrator on the remote computer, then the login connection box will appear.
Microsoft Windows NT and Windows 2000 have two types of networking organization—workgroups and domains.
The workgroup model implements a peer-to-peer network where each computer within the workgroup both accesses resources of the other computers within the workgroup and provides resources to be used by other computers in the workgroup. There is no centralized authentication within this model, so each computer must maintain its own list of users. Thus, membership within a workgroup is loosely defined.
The domain model implements centralized authentication and strictly defined membership. Instead of each server defining its own set of users, the set of users is defined only on the domain server.
Array Manager allows consoles in either model to connect to server agents. In the domain model, the user running the Array Manager console has a domain account that is a valid account on the server running the Array Manager agent.
In the workgroup model, the user running the Array Manager console has a valid local account with administrative rights on the system running the Array Manager agent. Array Manager does not restrict access by workgroup membership. In fact, you can use the workgroup model when you want to connect between a computer in a workgroup and one in a domain. This also applies in a situation where the console and the agent are on computers in two different domains.
From the Array Manager console, you can view all the computers within any connected Microsoft® Windows NT or 2000 domain or in the administrator's primary Novell® Directory Services (NDS) tree that have the Array Manager software installed on them.
In Array Manager, left-click My Network Places and then Microsoft Windows Network to display all the domains attached to the network. You can view Microsoft Windows NT/2000 Array Manager computers. You must log on to a computer before you can manage storage devices connected to that computer.
NetWare Array Manager computers are also viewed in My Network Places. In Array Manager, left-click My Network Places, then NetWare Services, and then NetWare Servers to display all NetWare computers running Array Manager that have been found on the network. It is possible that some NetWare computers that are running Array Manager will not be found. You can still connect to these computers as described in the following sections.
From the Array Manager console, you can view all the servers within any connected Microsoft Windows NT or Windows 2000 domain that have the Array Manager software installed on them. You need administrator-level access rights to install and use Array Manager.
The following sections describe the requirements and methods for connecting to a remote computer.
You can remotely log on to a Microsoft Windows NT or Windows 2000 Array Manager or Disk Management computer if you meet the following logon conditions:
A remote computer with the local Administrator rights of the remote computer system.
A remote computer in a domain with the domain administrator rights.
A remote computer in a different domain, which has a trusted relationship, with the domain administrator rights.
You can remotely log on to a NetWare Array Manager server with these conditions:
A remote computer to which you have administrator or supervisor rights.
You can connect to a remote computer using either of the following methods:
Use the following procedure to connect to a remote computer from the Array Manager console:
Select Connect from the Computer pull-down menu or right-click the My Network Places icon and select Connect.
The Connect to Computer dialog box appears.
Type the name of the computer to connect to.
For a NetWare computer, you must type in the DNS host name or IP address, and not
the NetWare computer name that appears in NDS.
The second check box is inactive (dimmed) unless the Add to Favorites folder check
box is checked. When you add a remote computer to Favorites, Array Manager places
the computer in the Favorites folder and will remember the logon information for
accessing that computer as long as the current session of Array Manager is running.
If you select Add to Favorites folder, you can also select Reconnect at next start of
application so that Array Manager will attempt to connect to the remote computer
whenever the program is started.
For more information on Favorites, see Using Favorites later in this chapter.
The Remote Connection dialog box may appear, depending on the type of computer you are connecting to.
The Remote Connection dialog box will not come up if you met the security logon
conditions when you logged on initially—that is, your logon name and password
match the user name and password of an administrator account on the remote
computer.
To understand more about why the Remote Connection dialog box sometimes
appears and at other times it does not, see the following sections:
If the Remote Connection dialog box appears, fill in the user name and password by selecting one of the following steps:
Type the administrator account name and password for the computer you want to connect to. You can select the domain as well from the pull-down list, but you don't have to.
OR
Type the domain administrator account name and password of the domain the computer is in (or a trusted domain to the computer). In these cases, you must select the domain from the pull-down list.
These domain names appear under My Network Places/Microsoft Windows
Network. The domain field is not needed when connecting to a NetWare computer
running Array Manager.
Note If a domain name is not selected, then Array Manager uses a local user account.
Click Connect.
This connection may take as long as 5 minutes to complete. The domain name is
automatically updated in the window when you change it. The computer icon for the
computer you connected to displays in the tree view of the Array Manager console.
To connect to a remote computer from a command line:
Open a DOS command shell.
Enter the following as a single command string. You should only press the <Enter> key after you have typed the following command string in its entirety.
Computer Name is the name of the computer to which you are connecting.
DomainName is the domain to which the remote computer belongs. When connecting to a NetWare system, omit this parameter. It does not apply to NetWare.
Password is the password of a user with administrator or supervisor authority. When connecting to a remote system with Array Manager, it is recommended that the password be the same on both the local and remote system. When connecting to a NetWare system, omit the Password parameter. NetWare will prompt you for the password.
UserName is the name of a user with administrator or supervisor authority. When connecting to a remote system with Array Manager, it is recommended that the user name be the same on both the local and remote system. When connecting to a NetWare system, omit the UserName parameter. NetWare will prompt you for the user name.
When you connect to a NetWare server from an Array Manager console, you need to enter a DNS name, a Hosts name, or the IP address of the Netware Server to which you are connecting. When the connection is made, you will see the NetWare Server name on the console tree.
To do NetWare discovery for NetWare servers, you must have a NetWare client running on the machine on which you are running Array Manager console.
When you click NetWare Services, you see all the remote servers running NetWare displayed underneath.
To log on to a displayed server, double-click it to bring up the Remote Connection dialog box.
Enter your full distinguished name and password and click OK.
For example, "cn=admin.0=dept"
This will log you on to the selected server, if you have administrator or supervisor
rights to that server. If you don't have supervisor rights to the server, then your
attempt to connect will be rejected.
My Network Places displays all connected NetWare servers.
Right-click the computer icon you want to disconnect from, or from the Computer pull-down menu, select Disconnect.
The remote connection ends with no message. The computer icon disappears from the
left tree view.
If the connection is lost for any other reason, a message appears that indicates the connection has been terminated. Array Manager removes the icon for that computer from the left tree view. Click OK to close the message box.
Array Manager uses the History folder in the tree view to store a list of the most recent connections made from the computer. You may want to delete computer icons from the History list.
You can use the Favorites folder in the tree view for easy storage and retrieval of frequently used computer names. The Favorites folder lets you display and retrieve NetWare computer names, as well as the names of Windows computers.
To place computer names into Favorites, select a computer name in the tree view and then drag and drop it into the Favorites folder.
You can also select the Connect command to connect to a remote computer and click the option Add to Favorites folder in the initial dialog box that comes up. Right-clicking the Favorites folder in the tree view also brings up a menu that has the Connect command.
To open any computer in the Favorites folder, left-click the computer's icon. If the Remote Connection dialog box appears, enter your name and password as appropriate to connect to this computer.
The Add to Favorites folder option is always paired with the option Reconnect at next start of application. If you select this option, Array Manager will attempt to connect to the "Favorite" remote computers when you restart Array Manager.
Note If you are logged on to the computer initially as a domain administrator, the
"Favorites" computers should come up automatically and appear in the tree view
(if you selected to reconnect at startup and the remote computers are online).
