RE: Attaching Hitachi HUS VM to IBM i LPARs -- MIDRANGE-L

Thanks Roberto, can you give me a reference what manual you found this in? I've been researching VIOS since this topic came up here and I have not found anything that discusses this yet.

Thanks
Dana

No, you do it this way:

Hitachi LUNS = 0 1 2 3 4

Dual VIOS redundantly connected to HITACHI sees LUNS 0 1 2 3 4 (important that the hdisks be configured as the manual says for Dual Vios, otherwise failover and load balancing fail due to LUN lock).

Dual VIOS present the same disks to each partition via vSCSI adapters.

IBM i sees both adapters and sees the 2 paths to each disk.

That's how i have it set up on a client, and that was how i read the manual, but let's wait for Sue or the Dr to be sure. Also, i'm not sure why they say IBM i 7.1, last i read it was IBM i 6.1.1 or later.

Best Regards,

Roberto

There was an update to this doc dated 05/14. Probably hasn't changed
much since John got his copy. I'm curious though, it says:

5) Dual VIOS with IBM"i" for v7.1.0 and above & VIOS 2.2 and above is
supported.
6) Virtual SCSI or vSCSI virtualization is supported.
7) We do not support vFC/NPIV with IBM"i" clients due to 520 block size.

So without NPIV, Dual VIOS would just let IBM i mirror two (sets) of
vSCSI disks?

Thanks John, that was my suspicion. I'll see if there's an update to
that doc...

I did setup our IBM I servers to use Hitachi storage and prior to
setup I contacted them in 2011 to make sure I could use their storage
arrays. They sent me a document titled: IBM I Support Document 03_25_11.pdf.
In that document it said: We do not support vFC/NPIV with IBM i
clients due to 520 block size. You may have to contact Hitachi to
find out of that has changed in the past 3 years. I ended up setting
up vSCSI as vSCSI virtualization is supported by Hitachi with a VIOS.

Subject: Attaching Hitachi HUS VM to IBM i LPARs

Our company currently uses Hitachi HUS VM for storage for AIX LPARs.
Now we are looking at a new P8 machine(s) to replace a boxes that
houses a total of 10 IBM LPARs and the question came up, why don't we
use storage in the Hitachi subsystem for this new box. The official
Hitachi line is that HUS VM supports storage as presented to VIOS, but I can't find any
confirmation that it supports NPIV to LUNs to IBM i LPARs. In addition,
since the Hitachi subsystem here already has replication set up to our DR
site, we could discontinue using iTERA for replication. Has anyone here
used Hitachi storage to attach to IBM i and/or with replication? Any
experience to share?

Thanks
Dana
