Diagnostics and Troubleshooting Reference Manual – Virtual SAN Taking one last view from the vSphere client, this time of the physical disks, a Lost Communication operation state against the disk in question is displayed. It is also beneficial to use the CLI in these situations, as additional information can be gleaned. esxcli vsan storage list - unknown This first ESXCLI command lists the storage on the host but the last entry in this truncated list displays a lot of unknowns. # esxcli vsan storage list naa.600508b1001cadff5d80ba7665b8f09a Device: naa.600508b1001cadff5d80ba7665b8f09a Display Name: naa.600508b1001cadff5d80ba7665b8f09a Is SSD: false VSAN UUID: 5209c0c3-2143-7031-b404-060642590295 VSAN Disk Group UUID: 52e4dd37-f670-2125-2a4b-14eb7a0a6140 VSAN Disk Group Name: naa.600508b1001c40e393b73af79eacdcde Used by this host: true In CMMDS: true Checksum: 108245589703025155 Checksum OK: true Emulated DIX/DIF Enabled: false Unknown Device: Unknown Display Name: Unknown Is SSD: false VSAN UUID: 5227c17e-ec64-de76-c10e-c272102beba7 VSAN Disk Group UUID: VSAN Disk Group Name: Used by this host: false In CMMDS: false Checksum: Checksum OK: false Emulated DIX/DIF Enabled: false . . Also note that the disk is no longer claimed by Virtual SAN as the In CMMDS: false indicates. This is the cluster monitoring and membership service, and Virtual SAN is no longer claiming it.

Diagnostics and Troubleshooting Reference Manual – Virtual SAN vdq –qH: IsPDL One other CLI command is the vdq command. This command has one very useful field in situations like this, and that is “IsPDL?”. It basically highlights if the device is in a state of PDL, or permanent device loss, which it is.
