Active Passive HP EVA on 11.31

[Dave Cast]

We have an Active-Passive EVA and I'm trying to present a lun from it to an 11.31 HPUX box. The 2 TB lun shows up in an ioscan, but I cannot create a VG in sam - it says 'unsuccessful'.....

I've had issues in reverse, I've presented luns from an Active-Active EVA to an HPUX 11.23 box before, once again the lun shows up - but you cannot create or do anything with it.

I've also noticed there seems to be a huge gap knowledge about this, HP techs onsite cannot answer such a question, and appear confused that I cannot do either. Surely someone must know?!

First of all it is very important to present a LUN in "hpux" mode (never default!) to a hp-ux host.


Active/passive EVAs are unsupported with 11.31, with 11.23 you need to use autopath/securepath.


Why not upgrading the EVA to active/active?

[Torsten.]

Well, you can adjust your system via scsimgr to use only a single path to a single controller of the EVA, but this is NOT what you really want to do!

Interestingly - and I did not notice this before - on our EVA 5000 there is NO OS choice when you create the Vdisk!

[Torsten.]

Maybe much too old?

What VCS version?

[Torsten.]

BTW, the os choice appears during vdisk presentation, not vdisk creation.

There are is not option while presenting a vdisk to choose what OS will be trying to use it. Hadn't noticed that before.

Sorry, this was not correct.

You need to select the host in HOSTS section (general tab), there you see/set the Operating System Type.

Must be HP-UX for HP-UX hosts.
