APPLIES TO:
Oracle Database - Enterprise Edition - Version 11.2.0.1 and later
Information in this document applies to any platform.
GOAL
Consider a 11.2 Grid Infrastructure with CLUSTER setup having OCR ,Vote File and ASM SPFILE on a diskgroup. Under certain circumstances you may wish to rename that diskgroup.
"renamedg" utility can be used to rename of the diskgroup when the diskgroup is dismounted.
But since the diskgroup contains OCR and Vote File we need to use an intermediate diskgroup for storing OCR and Vote File temporarily while renaming the actual diskgroup.
SOLUTION
Basic Steps to rename the diskgroup :
\1) Create a temporary diskgroup (TEMP) with suitable redundancy for OCR and Vote files.
\2) Move OCR and Vote file from
\3) Change ASM SPFILE location from
\4) Restart CRS in all Nodes to Startup CRS using New SPFILE from
\5) Dismount the OLD diskgroup in all cluster nodes that is not used by CRS.
