Hi,
We have recently presented a couple of 1TB Netapp shared LUNs to ESXi5.0 hosts. Now one of the LUN is invisible from ESXi hosts in cluster, another LUN is fine which is from same storage igroup. As per my request, storage team have represented the LUN to ESXi hosts but no luck, they have confirmed that no issues at storage end..
We have identified that all paths for this LUN are in dead state, they are not coming to active state even after rescan HBAs (rescanned HBAs individually from ESXi as well) also rebooted the ESXi hosts but no luck.. When I tried to active the paths by command from ESXi, getting error like path or HBA busy..
We have only 10 LUNs in ESX farm out of 9 are in use. I think ESXi 5.0 have limit to 256 LUNs, 1024 paths and LUN size can be 64TB, so no issues in that aspect..
Please provide your inputs..
Regards,
Surendra
