When you upgrade an ESXi host, vSAN is upgraded automatically. After upgrading all the ESXi hosts, upgrade the vSAN cluster objects such as vSAN on-disk format and vSAN HCL DB.

Note:

The disk format upgrade is optional. If you use a previous disk format version, your vSAN cluster continues to run smoothly. For best results, upgrade the latest on-disk format that provides the complete feature set of vSAN. For more information, see About the Virtual SAN Disk Format.

Procedure

  1. (Optional) Upgrade the vSAN Disk Format Using vSphere Client.
  2. Update vSAN HCL DB. For instructions, see KB 54945.

Results

vSAN disks are upgraded successfully.
