HACMP two-node cluster with two SAN storages mirrored using LVM

HACMP two-node cluster with mirrored LVM.

HACMP two-node cluster with two SAN storages mirrored using LVM. Configured 2 disk heartbeat networks - 1 per each SAN storage. While performing redundancy tests. Once one of SAN storage is down - cluster is going to ERROR state. What are the guidelines to configure heartbeat network in such environment.Configured 2 disk heartbeat networks - 1 per each SAN storage. While performing redundancy tests.

Hi The problem resolved. I can't post URLs here (due to limitations) so copy pasting whole discussion.1) You were right and I had a problem with one of volume groups logical volumes not fully mirrored
2) In general HACMP expects that mirrored volume group that is being varied to have Mirror Pool Strictness to be set as Superstrict
3) In case its not set as it there is a need to set Force varyon volume groups on Resource group start
