If a job already exists that references a reservation with the specified name, an
error message is returned: The specified reservation name is referenced by a
job.
Modify an advance reservation
1 Use brsvmod to modify reservations. Specify the reservation ID for the
reservation you want to modify. For example, run the following command to
extend the duration from 6:00 a.m. to 9:00 a.m.:
brsvmod -e "+60" user1#0
Reservation "user1#0" is modified
Administrators and root can modify any reservations. Users listed in the
ResourceReservation section of
lsb.resources, can only modify reservations
they created themselves.
Using brsvmod to modify advance reservations
Use brsvmod to make the following changes to an existing advance reservation:
◆ Modify start time (postpone or move closer)
◆ Modify the duration of the reservation window (and thus the end time)
◆ Modify the slot numbers required by the reservation (add or remove slots with
hosts)
◆ Modify the host or host group list (add or remove hosts or host groups)
◆ Modify the user or user group
◆ Add hosts by resource requirement (-R)
◆ Modify the reservation type (open or closed)
◆ Disable the specified occurrences of a recurring reservation
For example, assume an advance reservation is the box between the time t1 and t2,
as shown in the following figure:
