Hi RAC-DBAs,
installing the Oracle Clusterware CRS 10.2 on SLES10 with its multipath devices can be tricky.
Background: The tool formatting the OCR disks, clsfmt.bin, is buggy concerning multipath / device mapper devices and you will see root.sh fail and clsfmt spit out errors like:
clsfmt: Failure trying to resize OCR file from ... bytes to ... bytes clsfmt: Received unexpected error 4 from skgfifi
Oracle Patch Set 10.2.0.3 or one-off patch 4679769 from Oracle Metalink fixes this, but during install with runInstaller you are bound to the install kit 10.2.0.1 AND you cannot apply a patch before a product is fully installed. Subsequently, the root.sh fails and you have to clean up the mess manually and format the disks manually. I did not want do do so, I solved this problem in this way:
- downloaded Patch 4679769
- extracted it
- started runInstaller
- performed full configuration and install tasks until the point root.sh has to be executed. Left the message open.
- copied the clsfmt.bin from patch 4679769 directory to $ORA_CRS_HOME/bin on all nodes
- started root.sh (ran successfully)
- finished runInstaller as desired
Oracle Support approved this way on November 14th, 2007 in a service request.
Note: Please don’t forget to comment out the LD_ASSUME_KERNEL stuff in vipca and srvctl scripts on SLES10. Repeat this step after applying the 10.2.0.3 patchset.
Have always a good uptime, yours
