Yes Alan, two diffrent DB2 instances and potentially two different
release (fixpack) for DB2 (one node active node with fixpak 8 and
other with fixpak 10).
I have two partition per node on SAN :
first partition mounted /opt/IBM/db2 (content /opt/IBM/db2, /var/db2
(symbolic link) and homedir for dasusr1)
second partition mounted /datainst1 (content homedir for db2inst1 et
db2fenc1 and the data for instance and databases).
I have sync on all node
And i have disable in /etc/inittab this line for HA environnement
fmc:2345:respawn:/opt/IBM/db2/V8.1/bin/db2fmcd #DB2 Fault Monitor
I will use the passive node if one (and only one) of active is fault
