You need to know exactly which disk device corresponds to the missing datastore.
Immediately stop all I/O to the affected storage. Do not try to create a new VMFS datastore on the same disk, as this will overwrite the data.
VMFS is a clustered file system. The partition table, typically using a GUID Partition Table (GPT) format, contains crucial data about the structure of the LUN (Logical Unit Number) or local disk. If this table is gone, the ESXi host sees the disk as empty or unformatted. Accidental deletion: Using fdisk or partedUtil incorrectly.
Once the partition table is written:
partedUtil setptbl "/vmfs/devices/disks/naa.600508b1001c..." gpt "1 2048 5860527932 fb00"
ls /vmfs/devices/disks/
The documentation could be improved, but the support team was responsive and helped me through the process.
esxcli storage filesystem list
fdisk -l /vmfs/devices/disks/naa.xxxxxxxxxxxx
Example output: 60801 255 63 976773168
Use partedUtil setptbl to create a new GPT table.
If VMware native methods fail, specialized tools can scan raw disk for VMFS signatures.
