ESXi tagging a volume as a snapshot after a SAN change.

When the partition table is lost but VMFS signature remains:

If the partition table is intact but the datastore is missing from the inventory: vmware recovery vmfs partition

VMFS is a high-performance cluster file system designed specifically for virtual machines. It allows multiple ESXi hosts to read and write to the same storage simultaneously. When a partition goes "missing," it is rarely the data itself that has vanished. Usually, the issue lies within the partition table (MBR or GPT) or the VMFS metadata. Common reasons for partition loss include:

Use vicfg-cfgbackup to save your ESXi host configurations. ESXi tagging a volume as a snapshot after a SAN change

Accidentally deleting a datastore or local partition.

Identify the device path (e.g., /vmfs/devices/disks/naa.600... ). When a partition goes "missing," it is rarely

VMware Virtual Machine File System (VMFS) is a high-performance cluster file system used by ESXi hosts to store virtual machines, templates, and ISO files. Accidental deletion, partition table corruption, or metadata damage can render a datastore inaccessible. This paper outlines diagnostic steps and recovery methods for VMFS partitions, focusing on software-based approaches.

Recovering a VMFS partition is possible in most accidental deletion or partition table corruption scenarios. The first step is always to stop writing to the disk. Native ESXi commands ( esxcfg-volume , partedUtil , vmkfstools ) often succeed. For complex metadata damage, Linux‑based vmfs‑tools or commercial software provides a second line of defense.
