Are you using PowerPath or native MPIO?

We have several VIO server running on both CLARiiON (CX3 & CX4) and Symmetrix (DMX3) using PowerPath with no problems. We configure VIO identical to AIX and everything just 'works'.

vxdisk list communicates with the kernel devices to get the list of disk drives/luns available to the server. If that takes a long time to finish the list, then I'd look in to the following things first

->Check the output of powerpath & see if there
->Check for filesystems issues
->Check the device messages, dmesg, log messages
->Check for Vertias log messges

We are using MPIO.

We were told to use Failover Mode 3 in our VIO environment. Told it handles NDU Upgrades better. We however don't have veritas in our environment and are using Powerpath as well. So not sure if that mode takes those things into account or not.

Hey hersh. Thanx for the reply. Can you tell me who you mean by "we were told"? Was it EMC support, was the suggested Failover Mode in any form of a document you could share?

On PowerLink look for Knowledgebase article emc99467 - this lists the different settings for all the operating systems. See the attached PDF,

Can I say Kelleg told us? Thanks for the doc, it is nice having everything consolidated into one.

In case you are still curious, I believe it was our local support team that did the digging for us.
