Installing ITO Agents on the Managed Nodes
General Installation Tips for Managed Nodes
if [ $? -ne 0 ]; then
INTERFACE=`/usr/sbin/cluster/utilities/clgetif -a $BOOT_IP`
fi
if [ “$INTERFACE” != ““ ];
then
#IP has changed, set IP alias again on interface with SERVICE_IP
/usr/sbin/ifconfig $INTERFACE $ALIAS_IP alias
fi
The ALIAS_IP variable should contain the same IP address that was
used for the installation of the ITO agent. Remember to change the
ALIAS_IP variable if you copy the shell script to other nodes in the
cluster. This script gets service and boot IP addresses for the local node
and sets the IP alias on the interface where either of the two was found.
In addition, the script can be used as the post-event script for the
following HACMP events:
• acquire service address
• release service address
• swap adapter
Use the SMIT screens by entering the following command in a shell:
smit hacmp . Then select Cluster Configuration -> Cluster
Resources -> Change/Show Cluster Events . Next, select the
appropriate option from the list and fill in the Post-event Command
field. You can put the shell script in the following directory:
/usr/sbin/cluster/local .
Note that from time to time entries like this will appear in the file:
/var/lpp/OV/log/OpC/opcerror :
WARNING opcmsga (Message Agent)(8028) [genmsga.c:535]:
Communication failure to message receiver: Connection
request rejected (dce/rpc).Buffering messages.(OpC30-3)
These entries may safely be ignored. Messages are not lost: they are sent
to the ITO server after communication is re-established. This usually
takes no more than a few seconds.
Installing AIX HACMP Agents
The installation process is straightforward and does not differ from the
installation of the ITO agents on any other computer running AIX, with
the exception of the following:
• the IP alias address must be used as the IP address for the host on
which the ITO agent is to be installed.
