How To Recreate The Disk Group Containing OCR and Voting Disk If It's Not Mounting In Exadata (Doc ID 1384922.1)

Last updated on NOVEMBER 05, 2015

Applies to:

Oracle Exadata Hardware - Version 11.2.0.1 and later
Information in this document applies to any platform.

Goal

If the diskgroup SYSTEMDG is not mounting (because of multiple disk failures) then following procedure can be used to recreate this diskgroup.

This procedure should be followed if you are NOT able to mount the SYSTEMDG diskgroup even with FORCE option.


Sometimes if one of the disk is missing then diskgroup will not mount and will give error regarding missing disk but if all other members are available then we can mount the diskgroup with FORCE option and later drop the missing disk. Once the disk is replaced we can add this missing disk again to diskgroup.
