Determining logical disk on MSA1000 from Windows host

[Dan Andryszak_1]

I have several logical disks of the same capacity assigned to a Windows 2003 cluster.

I need to decommission a group and it's associated resources (i.e. physical disks, network name, ip address, etc.).

How can I map a physical disk with Disk Manager back to a logical disk on the array?

I can do this with EMC CLARiiONs and Navisphere Manager, but I have not been able to do this using HP tools (ACU - ACU/Cli). It may be obvious, but I can't determine how to do it.

Any help will be appreciated.

If you're using Secure Path, then you can do the mapping by comparing the LUN WWN (a 128-bit value that starts with "6"). On the Windows server, execute the command "spmgr display". On the MSA1000, at least it is possible with the CLI command "SHOW UNITS" (I don't recall whether the ACU/ADU displays this value, too).

Thanks for the reply.

I'll give it a try.

Dan:

Generally, the Logical Unit Number in ACU follows suite in Windows. The first LUN is usually the first shared disk, probably your Quorum resource and usually Disk 1 in Windows, unless you have a local disk 1. Then it might be disk 2.


Eitherway, you should be able to match up the disk target id with the LUN number in ACU. Just right click on the disks in Windows "Disk management" and click properties.
