I hope someone can help me here, we have bought a new QNAP SAN I want to connect to my VMware cluster but unfortunately my VMware servers cannot see the SAN. I have tested this QNAP on a standalone VMware server and it works no problem. The only difference is between the standalone server and the VMware cluster is we had a ISCSI MD3000 attached to the cluster which we had decommissioned. We followed this link http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1029786
to remove the MD3000. The VMware cluster is running our production servers and none of the servers in the cluster can be restarted any time soon.
If anyone can help me here that would be great!
