XP12K- Disks in HP-UX 11.23

[karthkri]

Hi,

I have many disks presented to HP-UX server from XP12K. How will i find a particular disk which is corrsponding to a particular Lun(CU LDEV) in XP. I other storages like EVA it is not a problem, checking from HP-UX for EG: /dev/dsk/c18t2d2 corresponds to Lun id 18, so i can go to EVA and see the presentation to find the Lun Id 18 for which Lun. Ive attached the disks from XP on my system.

Karthkri,

You can use xpinfo

example:-
xpinfo -f /dev/rdsk/c116t2d1

/dev/dsk/c18t2d2 = LUN18

because of the t2d2 values.
This is exactly the same for all array LUNs (eva/xp/...).

There is another tool that will help you to get more information: "xpinfo".
Ask your support for that tool.
