Remove cluster configuration on all cluster nodes first (of course you can backup the cluster snapshot if you need it - rallback procedure

Uninstall all HACMP filesets (you can use PATH:

smitty install
Software Maintenance and Utilities
Remove Installed Software
F4
and select all HACMP related software (look for cluster)

You can list it before with "lslpp -l |gre cluster"


To keep system running you have to:

1. Permanently replace boot IP address with service IP address (smitty tcpip)

2. All shared VGs has to be set with:

chvg -an VGname (to be Auto Varyon after system reboot)

3. All filesystems resided on that VGs should be set to automounted after system reboot:

chfs -A yes /filesystem

4. Add yout start script (you was using it in Application Server in Cluster) to for example:

/etc/inittab


5. You can also unconfigure stby addresses and remove network cables from nodes which are not cluster now.

...an removing cluster configuration means:

smitty hacmp

Configure Cluster
Remove Cluster Definition

(on both nodes)
