Hi2all!

I have strange problem, using 2 vios scenario and one client partition. On client I see two disks using same PVID, but on different paths, and can not get it to failover when vios 1 is rebooted or turned off.

Client:
root@hostname #lspv
hdisk0 00c5d3402e990f5c rootvg active
hdisk1 00c5d3402e990f5c rootvg active

root@hostname #lspath
Enabled hdisk0 vscsi0
Enabled hdisk1 vscsi1

root@hostname #lscfg -vl vscsi0
vscsi0 U9117.MMA.655D340-V4-C143-T1 Virtual SCSI Client Adapter
root@hostname #lscfg -vl vscsi1
vscsi1 U9117.MMA.655D340-V4-C144-T1 Virtual SCSI Client Adapter

both VIOS:

When it's working correctly, you don't see two disks, you see a single disk with two paths.

I'm not sure from the information you've provided what is incorrectly defined, but failover isn't designed to work the way you have it configured.

You'll need to provide more info, like lsdev, maybe lspath, lspv, lsmap from both VIO servers.

Also, what's the back-end storage? Although lsdev should show us that.

Could you provide us in addition :

lscfg -vl hdisk0
lscfg -vl hdisk1

Thanks guys, most of the commands you asked for, I wrote in last post.
Anyway, I mapped new disk and migrated the data over, so the problem is solved (for now).
