Issue/Introduction
Symptoms:
After a RAID rebuild following a disk failure, you may experience these symptoms:
VMFS datastore is missing
VMFS datastore cannot be accessed or browsed
Virtual machines are showing as Inaccessible
Virtual machines cannot be powered on
Resolution
When a RAID rebuild takes place, the physical ID of the LUN may change, which causes the ESX/ESXi host to detect the LUN as a snapshot.
To resolve this issue:
Resignature (or force mount) the LUN, see
Troubleshooting LUNs detected as snapshot LUNs in vSphere (1011387)
