Recover - Vmfs Partition Table

ls /vmfs/devices/disks/ Look for the affected LUN. It will look something like: naa.600601605a281b00c1d5b86c5a3be011

On ESXi:

Now create partition:

partedUtil set /vmfs/devices/disks/naa.xxxxxxxxxxxx 1 2048 976773167 AA31E02A-400F-11DB-9590-000C2911D1B8 0 Then rescan:

df -h /vmfs/volumes/ If the datastore shows but VMs are not visible, run: recover vmfs partition table

If the partition table becomes corrupted—due to accidental overwriting, failed resizing operations, controller issues, or human error—the datastore becomes inaccessible, and all VMs hosted on it appear lost. The good news: In many cases, without data loss.

List all storage devices:

vim-cmd hostsvc/datastore/info If automatic restore fails, you may need to manually recover the partition starting sector. Find the VMFS superblock offset VMFS superblock is typically located at sector 128 (1MB offset, 512-byte sectors). Use dd and hexdump :
