Getting "(2106) Disk storage server is down" on all MSDP clients after upgrade to 7.6.0.2 from 7.5.0.6

Turned out to be a polling problem. Learned that if you have more than one media server credentialed for the storage pool (for failover) and the media server that hosts the storage pool goes offline (like for an upgrade), the client will choose another media server to check to see if the storage pool is up. If the media server is across the WAN and does not respond quick enough, it marks the storage pool as offline which is what was happening to us.
So I should have deselected all but the storage server under Credentialed servers for the upgrade.
