Detect disk on SAN Hitachi

[Claude Lanouette_1]

Hi,

I just install HP-UX 11i v26 and we have 2 HBA card connect to a Hitachi SAN and we create 90 LUN and i see only 30 LUN (disk) in SAM.

What i need to do to see all disk?

Wow - 11i v26 !!!
I only know v1, v2 and v3
;-)

How about "ioscan" - does it show more?
Did you check the LUN presentation and zoning?

I din't see more with ioscan, i see 41 disk in SAM and 82 with ioscan.

How i can check the LUN presentation and zoning.

The current list of 81 is probably a multi-path ( 41 * 2 ).

90 luns created total ? wow.


As you are approaching the 90 range and 41 are being seen, I might start to suspect some HBA, FA, masking limitation.

As you are asking how to check zoneing etc, I assume you did not set any of this up. Start talking with your storage admin. They should be responsible for helping known array limitations and respective OSs.

I agree with Tim - ask your SAN/Storage admins. I'm sure they can help you.

I will check with my SAN admin but HP-UX 11iv2 suppose to support just at 1536 Lun's
