Get MPIO to work with Hitachi (HP XP) SAN by mrn
Posted: 24 Aug 06

Struggled with this for a while, but here's how I setup MPIO with a HP XP 12000 (Hitachi SAN)

odmget -qattribute=mpio_model_map PdAt > /tmp/odm.orig

cp /tmp/odm.orig /tmp/odm.modif

vi /tmp/odm.modif

change all occurances of HITACHI to HP<><><><><> where <> is a space

1,$s/HITACHI/HP     /g

odmadd /tmp/odm.modif


if you already have disks showing remove and re-run cfgmgr.

lsdev -l hdisk* > /tmp/disks

edit /tmp/disks and remove internal disks from file (hdisk0,1...)

for i in `cat /tmp/disks` ; do
rmdev -l $i -d

This method doesn't support load balancing (you'll have to get a copy of HDLM to do that)
Hope this helps
