eva4400 preferred path

Hello,

Not sure if this should be in SAN storage or not but here goes.

I have an eva4400 with 2 node HPUX 11.31 cluster.

Each node has a single dual port HBA.

The vdisks have been configured as "No Preference".

If i go through the the luns and split up the heavy users evenly across the controllers using Failover/Failback would this load balance the traffic?

Is this supported in 11.31?

Do i need do anything special to make this work and can i update it on the fly?

Thank you.

In 11.31, with the new I/O stack and persistent DSF's, the theory is that you should not have to manually manage the alternate paths. HP-UX is supposed to do everything for you automatically.
