Host Status
Host status describes the ability of a host to accept and run batch jobs in terms of
daemon states, load levels, and administrative controls. The
bhosts and lsload
commands display host status.
bhosts
Displays the current status of the host:
bhosts -l
Displays the closed reasons. A closed host will not accept new batch jobs:
% bhosts
HOST_NAME STATUS JL/U MAX NJOBS RUN SSUSP USUSP RSV
hostA ok - 55 2 2 0 0 0
hostB closed - 20 16 16 0 0 0

STATUS Description
ok Host is available to accept and run new batch jobs.
unavail Host is down, or LIM and sbatchd are unreachable.
unreach LIM is running but sbatchd is unreachable.
closed Host will not accept new jobs. Use bhosts -l to display the reasons.
unlicensed Host does not have a valid license.
Closed reason Description
closed_Adm An LSF administrator or root explicitly closed the host using badmin
hclose. Running jobs are not affected.
closed_Busy The value of a load index exceeded a threshold (configured in lsb.hosts,
displayed by bhosts -l). Running jobs are not affected. Indices that exceed
thresholds are identified with an asterisk (*).
closed_Excl An exclusive batch job (i.e., bsub -x) is running on the host.
closed_Full The configured maximum number of running jobs has been reached.
Running jobs will not be affected.
closed_LIM sbatchd is running but LIM is unavailable.
closed_Lock An LSF administrator or root explicitly locked the host using
lsadmin limlock. Running jobs are suspended (SSUSP). Use
lsadmin limunlock to unlock LIM on the local host.
closed_Wind Host is closed by a dispatch window defined in lsb.hosts. Running jobs are
not affected.
