]DESCRIPTION
Remotely logs in to a lightly loaded host.
By default,
lslogin
selects the least loaded host, with few users logged in, and remotely logs in to that host using the UNIXrlogin
command.In a MultiCluster environment, the default is to select the least loaded host in the local cluster.
OPTIONS
-v
Displays the name of the host to which
lslogin
remotely logs you in.-m "host_name ..." | -m "cluster_name ..."
Remotely logs in to the specified host.
With MultiCluster job forwarding, when a cluster name is specified, remotely logs in to the least loaded host in the specified cluster, if the remote cluster accepts interactive jobs from the local cluster (see
lsf.cluster(5)
).-R "res_req"
Remotely logs in to a host that meets the specified resource requirement. The resource requirement expression restricts the set of candidate hosts and determines the host selection policy.
For a complete explanation of resource requirement expressions, see
lsfintro(1)
. To find out what resources are configured in your system, uselsinfo(1)
andlshosts(1)
.rlogin_options
Specify remote login options passed to the
rlogin
command.If remote execution fails,
lslogin
will log in locally only if the local host also satisfies required resources; otherwise, log in will fail.-h
Prints command usage to
stderr
and exits.-V
Prints LSF release version to
stderr
and exits.EXAMPLE
%
lslogin -R "select[it>1 && bsd]"
Remotely logs in to a host that has been idle for at least 1 minute, that runs BSD UNIX, and is lightly loaded both in CPU resources and the number of users logged in.

DIAGNOSTICS
Because
lslogin
passes all unrecognized arguments torlogin
, incorrect options usually cause therlogin
usage message to be displayed rather than thelslogin
usage message.[ Top ]
