Firmware/Driver upgrade to support >8 luns on HDS 9960 array

[John Tyler]

Our local HDS guy mentioned that HP is releasing a HP/Ux 11 patch or driver upgrade to eliminate the 8 LUN limitation when connected to HDS 9900s.

Has anyone heard about this or confirm this information.

Our plan to buy a couple of N-class servers is on hold since our storage is Hitachi only and i hate to create huge luns just to fit disk requirement within 8 luns.

Ven,

We have inquired with HP about this issue and an EMC Symmetrix. We were told by HP that the LUN field in the OS is a 3 bit number, so you can only have 8 Luns per target. However, if you are running 11i (maybe even 11.0) with certain patches AND on a superdome, then you can have 16.

When I talked with HP about this a couple of months back, the backline engineer didn't see this changing soon.

What I've been told is that there is a firmware upgrade to the HDS box to allow > 8 LUNs. I understand that it is now available.

Good luck.
