partedUtil set /dev/disks/naa.YOUR_DISK_ID 1 128 <end_sector> FB 0 Then rescan and mount. If native tools fail, use a Linux VM with the corrupted disk attached (physical RDM or passthrough).
voma -m vmfs -f fix -d /vmfs/devices/disks/naa.YOUR_DISK_ID -f fix can cause data loss if the corruption is severe. 5. Recover Without VOMA (Manual Partition Repair) Sometimes the partition table is corrupt but VMFS data remains. a) Identify partition start sector Use fdisk or partedUtil :
esxcfg-datastore -m "/vmfs/devices/disks/naa.YOUR_DISK_ID:1" "DatastoreName" voma is the primary tool for VMFS repair. recover vmfs datastore esxi 5
ls /vmfs/devices/disks/ Check if VMFS volume is mounted:
esxcfg-datastore -l List VMFS volumes and their partitions: partedUtil set /dev/disks/naa
partedUtil get /dev/disks/naa.YOUR_DISK_ID Look for VMFS partition type ( FB ). If partition table lost, recreate first partition starting at sector 128 (typical) or 2048 with VMFS type:
esxcfg-datastore -u "DatastoreName" Mount: ls /vmfs/devices/disks/ Check if VMFS volume is mounted:
vim-cmd hostsvc/storage/refresh Unmount first:
