How to move ASM spfile to a different disk group [ID 1082943.1]
Goal
The goal is to move ASM spfile from one disk group to another.
During initial ASM setup the spfile might have been created in a default disk group (e.g. DATA). The requirement is now to move the ASM spfile to another disk group.
According to Oracle ASM documentation it should be possible to use 'asmcmd spmove' command to move ASM spfile:
Oracle Database Storage Administrator's Guide 11g Release 2 (11.2)
Section ASMCMD Instance Management Commands
spmove
Purpose: Moves an Oracle ASM SPFILE from source to destination and automatically updates the GPnP profile.
But an attempt to move the ASM spfile fails as follows:
$ asmcmd spmove +DATA/asm/asmparameterfile/REGISTRY.253.715881237 +PLAY/spfileASM.ora
ORA-15032: not all alterations performed
ORA-15028: ASM file '+DATA/asm/asmparameterfile/REGISTRY.253.715881237' not dropped; currently being accessed (DBD ERROR: OCIStmtExecute)
Solution
To move ASM spfile to another disk group, either make use of intermediate pfile:
1.Create intermediate pfile from the current spfile
2.Create spfile in a new disk group from the intermediate pfile
3.Restart the HA stack to verify that ASM starts up fine with moved spfile
4.Remove the original spfile
or use 'asmcmd spcopy' command
1.Copy spfile with -u option - to update GPnP profile in RAC environment
2.Restart the HA stack to verify that ASM starts up fine with copiedspfile
3.Remove the original spfile
This is an example of moving ASM spfile in a single instance environment, by making use intermediate pfile
1. Create intermediate pfile from the current spfile
$ sqlplus / as sysasm

Verify that the new spfile is being used

The use of new spfile can also be verified with asmcmd as follows:
$ asmcmd spget
+PLAY/asm/asmparameterfile/registry.253.715963539
4. Remove the original spfile
$ asmcmd rm +DATA/asm/asmparameterfile/registry.253.715881237
And this is an example of moving ASM spfile with 'asmcmd spcopy'
1. Copy spfile with -u option - to update GPnP profile in RAC environment
$ asmcmd spget
+DATA/asm/asmparameterfile/registry.253.722601213
$ asmcmd lsdg

$ asmcmd spcopy -u +DATA/asm/asmparameterfile/registry.253.722601213 +PLAY/spfileASM.ora
2. Restart the HA stack to verify that ASM starts up fine with copiedspfile
$ crsctl stop has
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on '<server>'
...
CRS-4133: Oracle High Availability Services has been stopped.
$ crsctl start has
CRS-4123: Oracle High Availability Services has been started.
$ asmcmd spget
+PLAY/spfileASM.ora
3. Remove the original spfile
$ asmcmd ls -l +DATA/asm/asmparameterfile
Type Redund Striped Time Sys Name
ASMPARAMETERFILE UNPROT COARSE JUN 25 10:00:00 Y REGISTRY.253.722601213
$ asmcmd rm +DATA/asm/asmparameterfile/registry.253.722601213
NOTE: The disk group that holds ASM spfile has to have COMPATIBLE.ASM value of 11.2 or higher.
