Controlling Hosts
Hosts are opened and closed by an LSF Administrator or root issuing a command
or through configured dispatch windows.
Close a host
1 Run badmin hclose:
badmin hclose hostB
Close <hostB> ...... done
If the command fails, it may be because the host is unreachable through
network problems, or because the daemons on the host are not running.
Open a host
1 Run badmin hopen:
badmin hopen hostB
Open <hostB> ...... done
Configure Dispatch Windows
A dispatch window specifies one or more time periods during which a host will
receive new jobs. The host will not receive jobs outside of the configured windows.
Dispatch windows do not affect job submission and running jobs (they are allowed
to run until completion). By default, dispatch windows are not configured.
To configure disp atch window s:
1 Edit lsb.hosts.
2 Specify one or more time windows in the DISPATCH_WINDOW column:
Begin Host
HOST_NAME r1m pg ls tmp DISPATCH_WINDOW
...
hostB 3.5/4.5 15/ 12/15 0 (4:30-12:00)
...
End Host
3 Reconfigure the cluster:
a Run
lsadmin reconfig to reconfigure LIM.
b Run
badmin reconfig to reconfigure mbatchd.
4 Run bhosts -l to display the dispatch windows.
