After restarting the ESXi host that housed my VCSA the datastore that contained the vCenter VM was missing from the web UI. The disk still shows up but rescanning and refreshing does not mount the datastore.
The datastore is backed by a VMFS partition on the same disk as the ESXi installation. Was not able to find any snapshots of the VMFS. Running:
ls -lisa /vmfs/devices/disks/
I can see both the disk and a mapping for the partition.
partedUtil getptbl /dev/disks/naa.5000c5003b6c54af
Shows no issues with the partition table.
Only clue I can find is in the vmkernel.log.

Somewhat of a VMWare newbie, any suggestions for where I should go from here?
