I have upgraded on host from ESXi 4.xx to version 5 but two of the luns are now not found (SBD partitions). Could someone please confirm my threory or point me in the right direction.
On upgrade to ESXi does it change the configuration of the shared vmdk. Am I having issues with the mapping (Virtual disk ‘Hard Disk 3’ is mapped direct-access LUN that is not accessible) because the other host has not been upgraded ESXi 5 yet and the clustered VM has the vmdk in use??
