Identifying the HP EVA LUNs on HP-UX 11iv3
Yesterday’s post about CLARiiON reminded me a similar issue I observed when the storage array is an HP EVA. If you ask for the disk serial number with scsimgr you always get the same number, in fact this number is the serial of the HSV controller.
The key to match your disk in the HP-UX host with the LUN provided by the EVA arrays is the wwid attribute of the disk.
root@ignite:/ # scsimgr get_attr -D /dev/rdisk/disk10 -a wwid SCSI ATTRIBUTES FOR LUN : /dev/rdisk/disk10 name = wwid current = 0x600508b40006cb700000600008bb0000 default = saved = root@ignite:/ #
If you look for this value in Command View will see that is the same as the World Wide LUN Name and the UUID.
### UPDATE ###
Thanks to my friend Jean and to Greg who reminded me that like Greg said in his comment is much easier to match the Word Wide LUN Name with the evainfo tool. Thanks to both of you :-)

Where can I get EVAinfo? Like Greg said EVAinfo is distributed on the HP StorageWorks Storage System Scripting Utility CD (SSSU) since 8.0 version. Unfortunately I couldn’t find, yet, a public download URL but the CD is distributed with the hardware so if you own an EVA is probably you already have the media.
Thanks to Jean, man it seems that I owe you more than a couple of beers ;-D, here it is the URL of the CD. You will find the EVAinfo utility inside the HP StorageWorks Command View SSSU v9.2 software ISO.
