Check partition information:
fdisk -l /vmfs/devices/disks/naa.xxxxxxxxxxxx ESXi has a built-in recovery tool that can restore a VMFS partition table if the VMFS superblock is intact. Method A: Using partedUtil restore First, check if a VMFS volume is detectable: recover vmfs partition table
esxcfg-storage -r vim-cmd hostsvc/datastore/reload Check mounted datastores: Now create partition: VMware Virtual Machine File System
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. failed resizing operations
Now create partition:
VMware Virtual Machine File System (VMFS) is a high-performance cluster file system designed for storing virtual machine files, including disks, snapshots, and configuration data. The partition table on a VMFS datastore is a critical component that defines where the VMFS volume begins and ends on the physical LUN or disk.
