Adding a host of an existing type using lsfinstall
Compatibility
notice
lsfinstall is not compatible with clusters installed with lsfsetup. To add a
host to a cluster originally installed with lsfsetup, you must upgrade your
cluster.
1 Verify that the host type already exists in your cluster:
a Log on to any host in the cluster. You do not need to be root.
b List the contents of the LSF_TOP/6.0 directory. The default is
/usr/share/lsf/6.0. If the host type currently exists, there will be a
subdirectory with the name of the host type. If it does not exist, go to
“Adding a host of a new type using lsfinstall” on page 77.
2 Add the host information to lsf.cluster.cluster_name:
a Log on to the LSF master host as root.
b Edit LSF_CONFDIR/lsf.cluster.cluster_name, and specify the
following in the Host section:
i The name of the host.
ii The model and type, or specify ! to automatically detect the type or
model.
iii Specify 1 for LSF server or 0 for LSF client. For example:
Begin Host
HOSTNAME model type server r1m mem RESOURCES REXPRI
hosta ! SUNSOL6 1 1.0 4 () 0
hostb ! SUNSOL6 0 1.0 4 () 0
hostc ! HPPA1132 1 1.0 4 () 0
hostd ! HPPA1164 1 1.0 4 () 0
End Host
c Save your changes.
3 Run lsadmin reconfig to reconfigure LIM.
4 Run badmin mbdrestart to restart mbatchd.
5 Run hostsetup to set up the new host and configure the daemons to start
automatically at boot from /usr/share/lsf/6.0/install:
# ./hostsetup --top="/usr/share/lsf" --boot="y"
6 Start LSF on the new host:
# lsadmin limstartup
# lsadmin resstartup
# badmin hstartup
7 Run bhosts and lshosts to verify your changes.
