Cleanup Failed CRS Install on HP-UX Itanium

Since we had to do this several times, the following is how to cleanup after a failed CRS Install on HP-UX Itanium. (Refer to MetaLink Note: 239998.1). There were problems with the rootdelete.sh and rootdeinstall.sh scripts so we always had to cleanup the failed install manually:

1. srvctl stop nodeapps -n (we didn't have to do this because our failed installs never got this far).
2. As root:
3. rm /sbin/init.d/init.cssd
4. rm /sbin/init.d/init.crs
5. rm /sbin/init.d/init.crsd
6. rm /sbin/init.d/evmd
7. rm /sbin/rc2.d/K001init.crs
8. rm /sbin/rc2.d/K960init.crs
9. rm /sbin/rc3.d/K001init.crs
10. rm /sbin/rc3.d/K960init.crs
11. rm /sbin/rc3.d/S960init.crs
12. rm -Rf /var/opt/oracle/scls_scr
13. rm -Rf /var/opt/oracle/oprocd
14. rm /etc/inittab.crs
15. cp /etc/inittab.orig /etc/inittab
16. If they are not already down, kill the EVM, CRS, and CSS processes.
17. rm -Rf /var/tmp/.oracle
18. rm -Rf /tmp/.oracle
19. remove the ocr.loc file
20. rm -Rf /* CRS Install Location */
21. De-install the CRS home in the OUI
22. Clean out the OCR and voting files with dd commands Example:
23. dd if=/dev/zero of=/dev/rdsk/voting bs=8192 count=2560
24. dd if=/dev/zero of=/dev/rdsk/ocr bs=8192 count=12800
25. rm -Rf /app/oracle/oraInventory

Once those are done, you can restart the OUI install of Clusterware at the very beginning. Oracle has also just released a new cleanup utility for failed CRS installs here is the link:

The new script didn't work for us either. Of course, I didn't try it after our system admins removed ServiceGuard so it may work now.
