Hi Frank
I always found it better to do a fresh 11i install. Follow these steps (assuming that Oracle and database/s are in their own VGs) - this list is NOT exhaustive (!) and I can't comment on WebSphere, although I assume you can re-install with ServiceGuard:
- Take a backup first!!
- Un-trust the system (if applicable)
- Backup the following files/directories:
/etc/cmcluster
/etc/oratab /etc/motd /sbin/init.d /usr/local/bin
/etc/rc.config.d /var/spool/cron/crontabs /etc/passwd /etc/group
/etc/hosts /etc/profile /etc/fstab /etc/inetd.conf /etc/ftpusers
/etc/networks /etc/pfs_fstab /etc/resolv.conf /etc/nsswitch.conf
/etc/services /etc/exports /var/adm/cron/cron.allow /var/adm/inetd.sec
- Get a print out of 'vgdisplay -v' & 'ioscan -fnC disk' and lssf all device files for each VG, just in case the device files change after the install and you then have a record of which hardware paths exist for each VG.
- Export all volume groups with vgexport options -s -p -m -f -v (see man page).
- Install the OS (to a spare disk if possible).
- Install SG/WebSphere (same version) for 11i.
- Restore and/or merge the files you backed-up earlier.
- Re-import the VGs (use the correct options for ServiceGuard cluster VGs).
- If the device-files have changed, you may need to alter the cluster lock device in the SG configuration. Hopefully they will stay the same.
- Re-trust the system (if applicable).
- SG should be operational without further intervention.
Hope this helps as a starting point, it is only intended as a general procedure and works for me, your set-up may be different - Keith
