• decomState: 0: This means that the node is currently not in maintenance mode.
• decomState: 4: This means that the node is currently entering maintenance mode.
• decomState: 6: This means that the node is currently in maintenance mode from a vSAN perspective.

• If ESXi from vCenter can enter maintenance mode (the option is available when right-clicking ESXi), try to enter and exit (or exit and enter) the maintenance mode.
• If this is unsuccessful, try to exit the vSAN maintenance mode by using the following command:

  • esxcli vsan maintenancemode cancel
