Command Reference Guide

Platform LSF Command Reference 159
Once a reservation is disabled for a period, it cannot be enabled; that is, the disabled
periods remain fixed. Before a reservation is disabled, you are prompted to confirm
whether to continue disabling the reservation. Use the
-f option to silently force the
command to run without prompting for confirmation; for example, to allow for
automating disabling reservations from a script.
rmhost [-n job_slots] [-m "host_name ... | host_group ..."] reservation_ID
Removes hosts or slots on hosts from the original reservation allocation. You must
specify either
-n or -m. Use -n to specify the number of slots to be released from
reserved hosts. Removing a host without
-n releases all reserved free slots on the
host. The new slot specification must be less than or equal to the actual reserved slot
number of the host.
You can only remove a whole host from a system AR.
How many slots or hosts can be removed depends on the number of slots that are
free as long as the reservation is active.
rmhost cannot remove more slots than are
free on the host. This applies to removing hosts on both one-time and recurring
reservations that are active. If you want to remove more slots from the reservation,
you must wait until running jobs finish or the reservation is inactive.
Options
-o Changes a closed advance reservation to open, or cancels an open reservation.
Changes the type of a reservation to be open or closed. If the reservation is open, all
jobs in the reservation become normal jobs, not subject to termination when the
reservation window closes. -on closes the reservation when it expires.
The running jobs of an open reservation are terminated when the reservation is
changed into closed. The termination times of running jobs of a closed reservation
are removed if the reservation is changed to open.
The termination time of running jobs is set by
mbatchd but checked by sbatchd.
Termination time is an absolute time based on master host, so all hosts in the cluster
should be synchronized with the local time on the master host. If sbatchd and
mbatchd are not synchronized, termination may not occur at the correct time.
-b begin_time | [+ | -]minutes
Replaces the begin time for a one-time reservation, or gives an offset in minutes to
the current begin time.
RESTRICTION: You cannot modify the begin time of an active reservation.
The begin time is in the form
[[[year:]month:]day:]hour:minute
with the following ranges:
◆ year: any year after 1900 (YYYY)
◆ month: 1-12 (MM)
◆ day of the month: 1-31 (dd)
◆ hour: 0-23 (hh)
◆ minute: 0-59 (mm)
