I have an ESX server array that I had connected to four HP SAN boxes. Unfortunately, HP only sent me three certificates (and I lost track) so it was running with only 3 of the 4 boxes cert'ed. I have called up HP, we found the cert and now all 4 are properly certified. However, vSphere no longer shows the connection to the san array or even the iscsi storage adapter at all!
I have very important data on this san and I cannot wipe it and start fresh...but I'm not sure where to go from here. Any suggestions would be helpful. Thanks!
