Re: MPIO for Linux OES Cluster server...

I just wasted three days or so on this. What you use depends
on the EVA model and VCS software level.

If you are running VCS 4.x on the EVA 3000/5000 or have
an EVA 4000/6000/8000, you can run the device-mapper
MPIO driver within SLES 9 SP3 (which comes with OES SP2).
In the latter case, look for the HP document "Device Mapper
Configuration Guide for HP Arrays".

If you have an EVA 3000/5000 with VCS 3.x, you will need to
run the QLogic 8.01.03 failover driver. This is because, at this
VCS level, the array is active-passive, which is not supported
by the device mapper Multipath software in the kernel. Look
for the HP document "Using the QLogic HBA driver for
single-path or multipath failover mode on Linux systems".
Warning, I got it going, but the driver parameters aren't close
to what is documented.
