Configuring Hard-Disk Drive Letters When Using Multiple Shared Storage Units

Before installing MSCS, it is very important to make sure that both nodes have the same view of the shared storage. Because each node has access to hard-disks that are in a common storage array, each node must have the hard-disk drive letters assigned identically. Perform the following steps to ensure that hard-disk drive letter assignments are identical:

1.Ensure the proper order of your cables.

The Windows NT Disk Administrator or Windows 2000 Disk Management utility displays all disks that are accessible from the first QLogic HBA followed by those that are accessible from the second QLogic HBA. Among the disks acces- sible from one HBA, the disks attached to a port with a lower port number on the Fibre Channel switch will be displayed first, followed by those attached to a port with a higher port number.

To ensure proper drive letter assignments, ensure that the first QLogic HBA detected by each node is connected to the same switch (the switch connected to PowerVault storage processor A) and that the second QLogic HBA detected is connected to the other switch (the switch connected to PowerVault storage processor B).
