This post validated Oracle note Doc ID 1589394.1.This note outlines the steps to move 12c GIMR (Grid Infrastructure Management Repository) to a different shared storage. In my environment I am using a 2 node system.  I am moving the GI Management Repository to Different Shared Storage +FASTDISK. This example is using version 12.1.0.2.

Take a backup:

[oracle-00.qa.alinafe.net:oracle:+ASM2:$~]:/u01/app/12.1.0/grid_1/bin/oclumon dumpnodeview -allnodes -v > GI_MoveBackup

1. Stop and disable ora.crf resource.

On each node, as root user:

[oracle-00.qa.alinafe.net:oracle:+ASM2:$~]:/u01/app/12.1.0/grid_1/bin/crsctl stop res ora.crf -init
[oracle-00.qa.alinafe.net:oracle:+ASM2:$~]:/u01/app/12.1.0/grid/bin/crsctl modify res ora.crf -attr ENABLED=0 -init

[oracle-01.qa.alinafe.net:oracle:+ASM2:$~]:/u01/app/12.1.0/grid_1/bin/crsctl stop res ora.crf -init
#[oracle-01.qa.alinafe.net:oracle:+ASM2:$~]:
/u01/app/12.1.0/grid_1/bin/crsctl modify res ora.crf -attr ENABLED=0 -init

#2. Issue the DBCA command to delete the management database

#As Grid User, locate the node that the Management Database is running by executing:

#[oracle-01.qa.alinafe.net:oracle:+ASM2:$~]:
/u01/app/12.1.0/grid/bin/srvctl status mgmtdb
Database is enabled
Instance -MGMTDB is running on node oracle-test01

[oracle-01.qa.alinafe.net:oracle:ASM2:$~]: /u01/app/12.1.0/grid/bin/dbca -silent -deleteDatabase -sourceDB -MGMTDB

#3B. For 12.1.0.2 only:

#a. As Grid User on any node execute the following DBCA command with the desired <DG Name>:

[oracle-01.qa.alinafe.net:oracle:+ASM2:$~]: /u01/app/12.1.0/grid/bin/dbca -silent -createDatabase -sid -MGMTDB -createAsContainerDatabase true -templateName MGMTSeed_Database.dbc -gdbName _mgmtdb -storageType ASM -diskGroupName +FASKDISK -datafileJarLocation /u01/app/12.1.0/grid/assistants/dbca/templates -characterset AL32UTF8 -autoGeneratePasswords -skipUserTemplateCheck
