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:

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 does not accept new jobs. Use bhosts -l to display the reasons.

bhosts -l

Displays the closed reasons (for details, see the bhosts command reference). A closed host does not accept new batch jobs:

lsload

Displays the current state of the host:

Status	Description
`ok`	Host is available to accept and run batch jobs and remote tasks.
`-ok`	LIM is running but RES is unreachable.
`busy`	Does not affect batch jobs, only used for remote task placement (such as lsrun). The value of a load index exceeded a threshold (configured in lsf.cluster.`cluster_name`, displayed by lshosts -l). Indices that exceed thresholds are identified with an asterisk (*).
`lockW`	Does not affect batch jobs, only used for remote task placement (such as lsrun). Host is locked by a run window (configured in lsf.cluster.`cluster_name`, displayed by lshosts -l).
`lockU`	Does not accept new batch jobs or remote tasks. An LSF administrator or root explicitly locked the host by using lsadmin limlock, or an exclusive batch job (bsub -x) is running on the host. Running jobs are not affected. Use lsadmin limunlock to unlock LIM on the local host.
`unavail`	Host is down, or LIM is unavailable.
