systemslab host reactivate

Description	Reactivate a draining or drained host, returning it to the scheduler.
Usage	systemslab host reactivate <UUID>

Description

The systemslab host reactivate command is the inverse of systemslab host drain: it lifts the cordon so the host can be scheduled experiment work again.

The transition depends on the host's current state:

Current state	Result
drained	Transitions to idle and rejoins the schedulable pool.
draining	Transitions back to busy, cancelling the pending drain while its current job keeps running.
any other state	Rejected with an error — only draining/drained hosts can be reactivated.

Reactivation takes effect immediately and takes no options — there is no --wait equivalent, because the host rejoins the scheduler as soon as the command returns.

Example

systemslab host reactivate 0194d39d-00d8-7fd1-5a72-1c3b7565ab66
