The setup is HP C-Class 8x BL480 Blades w/QMH2462 dual port hba going out via 2 VC_FC Interconnects. Egress Ports connect one each to 2 gps uplink to two MDS9509 Switches vsan 200 on switch A and vsan 400 on switch B. NPIV is enable on each switch. Both VSANs have single initiator zones configured for each Blade host with EVA5000 Vdisk storage luns selectively presented to Blades. Pair Windows 2003 EE running MSCS Active/Passive Cluster - 3 Luns are Cluster Disk Resources presented to cluster nodes. Luns presented to hosts appear and are available, however when Active or Passive is rebooted when host comes back up shared LUN is no longer showing up in Disk Manager or presented to host. If Cisco MDS9509 F_Port which is connected to HP Blade VC_FC Module is "shut/No Shut" or disabled then re-enable LUNS appear or are again presented to rebooted host.
Has anyone seen this problem?? Cisco Switches are running O.S. 3.2.1a per HP Blade Compatibility list.
