After rebooting several Virtual Connect Modules to test the failover behaviors I got myself in a situation in were the Virtual Connect Manager got completely unresponsive.

VMware vCenter Storage Views: Partial/No Redundancy
While exploring my software iSCSI initator environment I noticed that all my VM’s on every host are reporting a “Partial/No Redundancy”-status within the Multipathing Status even though I have Round Robin in place and thus 2 paths to the storage.

Lately we discovered some major problems with a couple of VM’s totally freezing for about 30 seconds, this problem seemed to only occur on several VM’s from one specific host, so time to do some research on this […]
