Hi Friends,
We have a server with node cluster. Resource group is active on primary node and offline on 2nd node. We use IPAT with aliases. My problem is that I have uninstall the cluster and configure the system as standalone system with same service IP.
Following is the configuration.
oslevel -s
5300-08-05-0846
HAcmp version 5.4 SP4
Application : SAP
Ifixes :
ID STATE LABEL INSTALL TIME ABSTRACT
=== ===== ========== ================== ======================================

4 S IZ39386 09/26/09 07:48:41 INCORRECT ERROR BY START_SERVER
5 S IZ38630 09/26/09 07:49:04 EVENT FAILS WHEN CLUSTER SVCS STOPPED
6 S IZ37919 09/26/09 07:49:30 IZ37919 IZ37462 IZ31367 HA541 SP4
How should I proceed?
I have chalked out the following plan
1) Stop the Cluster on both the nodes.
2) *Remove the cluster configuration on both the nodes :
Smity hacmp > Extended Configuration > Extended Topology Configuration
> Configure an HACMP Cluster >Remove an HACMP Cluster
3) Uninstalling the cluster
smitty install
Software Maintenance and Utilities
Remove Installed Software
F4
and select all HACMP related software (look for cluster)
4) Configure the etherchannel with service IP as in normal standalone system
5) Set autovaryon on all vg's to yes:
chvg -an vgname (to be Auto Varyon after system reboot)
6) Set automount on all filesystem to yes, so that filesystem get mounted after reboot:
chfs -A yes /filesystem
Another question that I have is, do i have to remove the ifixes before unistalling the cluster ?
I have never done the uninstallation of hacmp and I am bit tense as its one of our production system. Please suggest the correct steps for uninstalling the HACMP and running the system as standalone server serving through service ip. Its bit urgent thats why I am posting in all forums... sorry for this..
Thanks & Regards,
