1. Initial Diagnosis: Identify the Problem Before attempting recovery, determine the exact state of the datastore.
# List available partitions partedUtil get /dev/disks/naa.600xxxx partedUtil set /dev/disks/naa.600xxxx 1 0xFB 0 104857600 Reload partition table partedUtil fix /dev/disks/naa.600xxxx 3. Advanced Recovery (VMFS Metadata Repair) 3.1 Check & Repair File System (Read-Only First) From ESXi shell (requires SSH): recovery vmfs datastore
esxcli storage filesystem list | grep unmounted esxcli storage filesystem mount -l "DatastoreName" When restoring from a storage snapshot to the same host that sees the original LUN: recovery vmfs datastore
# Check filesystem (no repair) voma -m vmfs -f check -d /dev/disks/naa.600xxxx:1 recovery vmfs datastore
