trying to enable, disable, and force down a node

Use

state

and

session

fields to modify the state of a node. You can specify either

user-up

or

user-down

for the state.

user-enabled

and

user disabled

for the session.

A node becomes Offline/Enabled (red diamond) by PATCHing

'{"state":"user-down"}'

.

'{"state":"user-up"}'

to bring it up (green circle).

A node becomes Available/Disabled (black circle) by patching

'{"session":"user-disabled"}'

. Again,

'{"session":"user-enabled"}'

will bring it back alive.

If you patch both in one shot, i.e.,

'{"state":"user-down", "session":"user-disabled"}'

, the node status becomes Offline/Disabled (black diamond).

See also K12213214: Overview of colored status icons in the Configuration utility for the meanings of the states.

Additional info: You can get the available values for a parameter from

tmsh

. Just type the command halfway-through, and TAB. e.g.,

[root@ltm1213A:Standby:Changes Pending] config  tmsh
root@(ltm1213A)(cfg-sync Changes Pending)(Standby)(/Common)(tmos) modify ltm node sat state [TAB]
Values:
  user-down   user-up

I hope this would help.
