Finding out Lun information on lscfg -pvl

[tristezo2k]

I am very new to AIX, so sorry if I am badly mistaken.
As pointed out on
thread52-1546169
it seems that the LUN number/info is contained on the lscfg output.
However, I can not match my EMC SAN info with the output.
For instance:

# lscfg -pvl hdisk28
hdisk28 U7311.D20.102660B-P1-C03-T1-W5006048AD531D1E6-L17000000000000 MPIO Other FC SCSI Disk Drive

Manufacturer................EMC
Machine Type and Model......SYMMETRIX
Part Number.................
ROS Level and ID............35373733
Serial Number...............156D8000
EC Level.....................T..M
FRU Number..................@0
Device Specific.(Z0)........000004328F00000A
Device Specific.(Z1)........U
Device Specific.(Z2)........
Device Specific.(Z3)........
Device Specific.(Z4)........T..T
Device Specific.(Z5)..........

The information stays much the same for all disks on the same HBA but the L17000000000000 changes like
hdisk26 U7311.D20.102660B-P1-C03-T1-W5006048AD531D1E6-L0
hdisk27 U7311.D20.102660B-P1-C03-T1-W5006048AD531D1E6-L10000000000000
hdisk28 U7311.D20.102660B-P1-C03-T1-W5006048AD531D1E6-L17000000000000

The information I was given is:
New LUN FA path and HEX/DEC
06C0 07c1 10c1 LUN=10/16
06C2 07c1 10c1 LUN=11/17
06C4 07c1 10c1 LUN=12/18
06C6 07c1 10c1 LUN=13/19

06C8 07c1 10c1 LUN=14/20
06C9 07c1 10c1 LUN=15/21
06D6 07c1 10c1 LUN=16/22
06D8 07c1 10c1 LUN=17/23
and those three LUNs shoud be on that table.
Any help would be greatly appreciated.

Sebastian

If it's an EMC storage you probably have powerpath installed.
Try "powermt display dev=all", it should give you more information.

You should have an EMC tool/command called inq, which will give you the info your after.

The first 2 digits after the L should be the HEX LUN number for these type of LUNs, but try and verify this with the EMC tools or drivers as described above.

[tt]
L0 => LUN 00
L1000000000000 => L1 000000000000 => LUN 01
L10000000000000 => L10 000000000000 => LUN 10 = 16(dec)
L17000000000000 => L17 000000000000 => LUN 17 = 23(dec)

HTH,

Thanks for your help!
As p5wizard pointed out, those are the LUN numbers.
My mistake.
No powerpath installed on the VIO.
Not sure if inq is installed on the server.
Will check it tomorrow.

The Symmetrix Volume Id is embedded within the VPD Serial Number field.

lscfg -vl hdiskNNN |grep "Serial Number" | tail -1 | cut -c39-41

In the example you have shown the physical volume "hdisk28" is actually Symmetrix volume x6D8.

This is my understanding of the "current" VPD listing (AIX5L & AIX61) - it may change in later verions of AIX or the EMC ODM kit.

HTH.
