Cluster loses the reservation of the disk and fails.
Cluster requires a manual restart of the cluster service and manually brings the
drives back online.
Solution
To overcome the disruption of cluster service during the repair of the ISLs:
1. Access the management appliance at the destination site (site that was originally
the primary site) and disable access to the cluster nodes for any of the disks that
were failed over.
2. Repair the ISLs.
The EVA storage units will begin merging log data and negotiating state.
3. Re-present the failed over disks to the cluster nodes.
NOTE: To minimize disruptions to the cluster, determine a good maintenance time to
move the failed disks back to their original storage subsystem.
