We have a drive that is not failing over to the other node. I have not found any articles pertaining to this. If I disconnect the drive in Snapdrive 6.0.2 (as long as I dont delete the LUN) will the data still be available when I reconnect it? Is there another solution to this issue?
There could be connectivity issues, cluster resource problems, and many other reasons that could be causing this problem. Are you getting any errors when you do the failover?
Disconnecting the LUN should not cause any data loss but you'll need to use caution if there is an application or users writing to the LUN. I strongly suggest opening a ticket with support so they can have a look at the environment to see if there are any problems.
