• I have a Group of two EqualLogic PS4210, one in building A (in Storage Pool A) and another in building B (in Storage Pool B).
• The volumes are Synched Replicated between Storage Pool A and Storage Pool B.
• Clients connect to volumes using the EqualLogic Group IP address.

Issue

1. I Sync Alternative the volumes from Storage Pool A to Storage Pool B – all is fine with the volumes.
2. The firmware of the switch in building A is upgraded, where the EqualLogic is connected to, then the switch is rebooted.
3. When the switch is rebooted the devices connecting to the volumes now located in building B get disconnected!

Questions

1. Should I be doing something else to the EqualLogic devices before performing maintenance on switches where the EqualLogic devices are connected to?
2. Is there a document explaining the limitations of Synched Replication\ best practice?
3. Am I doing something wrong? Group configuration \ limitation of Synched Replication

Thanks
