All I have Citrix Data Store residing on 2 SQL Cluster nodes (Microsoft Server Cluster). Citrix Data Store resides in SAN volume. I do have a SAN Maintenance so I need to shutdown the 2 SQL Server nodes. Can anybody provide the procedure of shutting down the SQL nodes? Does Cluster Service need to be stopped prior to shutdown on both the nodes.. Is there any priority in shutting down both servers? If so while turning on the 2 Servers after maintenance where the Cluster Service needed to be started from? Can any one comment on this ..
