Controlling Hosts
Controlling Hosts
Closing a host
Opening a host
Dispatch Windows
Hosts are opened and closed by an LSF Administrator or root issuing a
command or through configured dispatch windows.
Run badmin hclose:
% badmin hclose hostB
Close ...... 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.
Run badmin hopen:
% badmin hopen hostB
Open ...... done
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 dispatch windows:
1 Edit lsb.hosts.
2 Specify on or more time windows in the DISPATCH_WINDOW column.
For example:
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.
Logging a comment when closing or opening a host
Use the -C option of badmin hclose and badmin hopen to log an
administrator comment in lsb.events. For example,
% badmin hclose -C "Weekly backup" hostB
The comment text Weekly backup is recorded in lsb.events. If you close or
open a host group, each host group member displays with the same comment
string.
