configure APA while MC SG is running
We have HPUX 11.31 installed on HP BL860c (Blade) series hardware.
We have configured Service Guard before APA configuration. Now we are facing problem in configuring APA. When we try to create a Link aggregate from SMH, it says that the link is used by MC/SG.
Please suggest, what approach should be considered while configuring APA if the MC/SG us running.

Re: configure APA while MC SG is running
If you want to configure APA on LAN cards which is used by MCSG, you need to configure APA first and then MCSG.
which mode of APA you are going to configure??
I don't find any benift if you configure LAN monitor. More over, I don't believe ,it is recommended.

Re: configure APA while MC SG is running
I know that we should go for APA then MCSG, but the thing is we cannot roll back the MCSG config. We need to take some way inbetween.
We need to configure LAN_MONITOR mode as redundant cables are across switches and can work only in failover mode. So "MANUAL" mode (used for Load balancing) is useless.

Re: configure APA while MC SG is running
it is possible, but you have to take down time to do this
by doing this:
#vi /etc/rc.config.d/hp_apaconf
#vi /etc/rc.confog.d/hp_apaportconf
#vi /etc/rc.config.d/netconf
for example
lan[1]=lan900
#cmhaltcl -f
unplumb the current lan card
#ifconfig lan(x) unplumb
#/sbin/init.d/hpapa start
#/sbin/init.d/net stop
#/sbin/init.d/net start
#netstat -in
then add entry to
#vi /etc/cmcluster/cmcluster.ascii
for example
NODE_NAME amdb01
NETWORK_INTERFACE lan900
STATIONARY_IP 10.4.102.11
NETWORK_INTERFACE lan4
copy thi file to all nodes
and then apply below comand to all nodes
#cmapplyconf -C /etc/cmcluster/cmcluster.ascii
and then,
# cmruncl
