I encountered an issue today while trying to check available disks from cluster storage by doing add disk, after verifying disks killed add disk window in cluster instead of clicking cancel button. After add disk window was killed it still added available disks to the cluster , removed newly added disks from the cluster which caused all cluster disks to go offline and then come online one of the disks which was added had binary files of SQL server.
Did anyone encounter this kind of situation in the past? Until today i was thinking killing a window is like closing it but was surprised to see killing a window in fact did what it should be doing when we accept by clicking OK button.
This is windows 2008 cluster with windows 2008 OS and SQL 2008 R2.
