MSA1000 Presenting LUNs to VMS

[Marcus Schack]

I was wondering if anyone can point me towards any documentation on how to present MSA1000 LUNs to a VMS box. I have created 8 logical disks but when we go to pick them up on the VMS side, it does not see them. I vaguely recall that unit ids are involved. Any help would be appreciated.

Hi Marcus,

Yes, unit IDs are compulsory for VMS LUNs.

Take a look at the CLI reference guide here:

http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01183955/c01183955.pdf

On page 28:

set unit_id <#>

Command options
#â the number of the LUN that is being assigned a name.

identifierâ name or number to assign to the specified LUN. The ID can be up to 230 alphanumeric characters or a decimal number in the range of 0 though 65535. If spaces are included in the name, quotation marks are required.

The hosts on the MSA1000 also need to be correctly set to OpenVMS - see page 40.

Hope this helps,

Regards,

Rob

While the text says 65535, I would not go higher than 9999:
