3PARdata VV Multi-Path Disk device UID

[stredovek]

I was involved in SAN disk extension and SAN team asked disk WWN  to be sure they extending correct disk.

I do not know how it can be gathered on HP platform. I found more HP programs installed but could not figure out

wchich to use ( example: HP Smart Storage administrator cli) . Can someone  advice?

You can use "showpd -i" to get the WWNs of each of the array disks but I don't think you want that.

You can use "showvv -d" to get the WWNs of each VV:

showvv -d
 Id Name    Rd Mstr  Prnt Roch Rwch PPrnt PBlkRemain -------------VV_WWN------------- -----CreationTime------ Udid
202 vv_00   RW 0/1/-  ---  ---  ---   ---         -- 60002AC000000000000000CA00018519 ...

And you can subset this by looking at the output of showvlun:

showvlun -a
Lun VVName HostName   -Host_WWN/iSCSI_Name-  Port Type Status ID
200 vv_00  hpx9300-06 5001438021E3675C      0:2:3 host active  1
201 vv_01  hpx9300-06 5001438021E3675C      0:2:3 host active  1
200 vv_00  hpx9300-06 5001438021E3675E      1:2:3 host active  1
201 vv_01  hpx9300-06 5001438021E3675E      1:2:3 host active  1

>from what command line you running  these commands?

These are from the HP 3PAR Remote CLI Client.

Or you can ssh into the CLI on the array and run them.
