@Bilal233, if no VMs are running on it then from the vSphere UI put the node in Maintenance Mode with 'No Action' option and then immediately take it out of MM.

Hi,

If you want to maintenance mode off, try below cli commands.

1. Check whether the host is in maintenance mode.
   esxcli --server=<server_name> system maintenanceMode get

Place the host in maintenance mode off.

esxcli --server=<server_name> system maintenanceMode set --enable false

Verify that the host is in maintenance mode.

esxcli --server=<server_name> system maintenanceMode get

@sunvmware1 , Unfortunately that won't actually work here - the host is not in ESXi/vSphere MM, that will just return 'false' when checked and setting this to false won't change anything.

@Bilal233 , aside from the MM/NODE_DECOM_STATE (which what I said above should fix without issues), I missed your point about it being isolated:

Was this host removed from the vSphere cluster?

Does it have a vsan-enabled vmk tagged and can vmkping the other nodes IPs from it?

Is the unicastagent list on it fully populated? (and do the other nodes have this nodes unicast entry)
