I have to identify few disks on the HP box Using LUN ID's and delete them.
These disks are presented from DS 8300 storage (IBM). In AIX i use lscfg -vpl hdisk10 to get the LUN-ID of a Disk but in HPUX i am finding it difficult to identify.
Can anyone help me with this please.
Thanks in Advance.

Druva

SolutionStart with ioscan to identify the LUNS.
You may need to use fcmsutil to identify world wide names as well.

Re: Problem in identifying Disks with Lun ID
Thanks for the response.
I am attaching the ioscan output and the Lun ID from DS8300. How can i match the lun-ID (storage) to IOscan output from HP box.
Can you please elaborate the use fcmsutil cmd to identify the lun-id. I tried this command but no luck :-(.

Druva

Re: Problem in identifying Disks with Lun ID
if you are using power path jtry using the command inq -clariion
# inq -clariion -no_dots
this will give you the list of luns with the device path. The second column from the last will the LUN number in Hex.
Sample output
/dev/rdsk/c4t0d0 :DGC :CX3-80WDR5 :HP03 :Ch2 CONT : 144703488: 0: 59:ASSIGNED
59 is the LUN id in Hex
Hopes this helps..

Re: Problem in identifying Disks with Lun ID
I think your Storage is not DS 8K or I dont have power path installed. The inq -clariion didn't work.
I had missed attaching the file with IOscan o/p.

Re: Problem in identifying Disks with Lun ID
scsimgr -p get_attr all_lun -a device_file -a wwid -a
this will show the wwid for each disk as well as its state.

Re: Problem in identifying Disks with Lun ID
Any other way to identify. I think there is some connection with cXtYdZ/hw_path with LUN-ID. But its too tricky.
Can anyone explain on the formula/calculation part to deduce cXtYdZ to Lun id. That will be of greate help.

Druva

see Tostern's post.
0/2/0/0.97.4.19.0.1.0 LUN 8
====================^
Take the last "0" and convert into 3 digit binary:
000
then take the "1" and convert too:
0001 000 ==> 0001000bin = 8 dec
This is decimal 8 = LUN 8.

Re: Problem in identifying Disks with Lun ID
if you have inq on your hpux server this may or may not work for you but you could try ./inq -shark_wwn (since shark is ibm)
not sure what ibm's storage tool would be but most storage types have a tool to find wwid's of luns. (inq-EMC, xpinfo-HP, lunstat-hitachi)

Re: Problem in identifying Disks with Lun ID
I couldn't find 'inq'. I am going to raise case with IBM, since DS 8k is a IBM storage, hopefully IBM will have a answer.
