currently available for package switching. However, you should not try
to restart HP Serviceguard, since data corruption might occur if another
node were to attempt to start up a new instance of the application that is
still running on the single node. Instead of restarting the cluster, choose
an appropriate time to shutdown and reboot the node, which will allow
the applications to shut down and then permit HP Serviceguard to
restart the cluster after rebooting.
Disabling identd
Ignore this section unless you have a particular need to disable identd.
You can configure Serviceguard not to use identd.
CAUTION This is not recommended. Consult the white paper Securing
Serviceguard at http://docs.hp.com -> High Availability ->
Serviceguard -> White Papers for more information.
If you must disable identd, do the following on each node after installing
Serviceguard but before each node re-joins the cluster (e.g. before issuing
a cmrunnode or cmruncl).
For Red Hat and SUSE:
1. Change the server_args parameter in the file
/etc/xinetd.d/hacl-cfg
from:
server_args = -c
to
server_args = -c -i
2. Change the server_args parameter in the
/etc/xinetd.d/hacl-probe file to include the -i
For SUSE this would be changed from:
server_args = -f /opt/cmom/log/cmomd.log -r /opt/cmom/run
to
server_args = -i -f /opt/cmom/log/cmomd.log -r
/opt/cmom/run
