Unable to create disk group in vSAN cluster - General vSAN error

Products

• VMware vSAN

Issue/Introduction

An attempt to create a disk group in vSAN fails with the following message:
Error: General vSAN error

Environment

vSAN

Cause

Disks are SED (Self-Encrypting Drive) locked as they were repurposed from a Nutanix HCI Cluster.

The following is repetitively logged in the /var/log/vmkernel.log for all the disks -->
####-##-##T##:##Z cpu##:#######)ScsiDeviceIO: ####: Cmd(0x45d941a6f0c8) 0x28, CmdSN 0x1 from world ####### to dev "naa.################" failed H:0x0 D:0x2 P:0x0 Valid sense data: 0x7 0x20 0x2

Sense data in the above message translates to the following:
0x7 - Data Protect
0x20 0x2 - Access Denied - No Access Rights
It indicates that ESXi is unable to read from the disk as its locked.

Resolution

Contact the hardware vendor to replace/repair the disks.
