Hello all! There is smth more to the item. I've used two VIOs for a single shared disk. I've removed reserve_policy for the shared disk on these two VIO-s and created LVM group on that disk. One node (node1) can see the disk from the VIO1 and the other node (node2) sees the same disk from the VIO2. Than I do "varyoffvg" one the active node and my LVM cluster group is switching over to the second node. No problems! The same thing happens when rebooting "active" VIO . (The only thing is about rootvg on the nodes - if you get your root disks from VIO you must sync your rootdg after VIO reboot)
So I don't see any problem if reserve_policy is set to no_reserve on the both VIO-s Regards, Pavel
