How To Move OCR and Vote Disks to Different ASM Disk Groups


Generally, for the Oracle Cluster Registry and Vote Disks, the disk group where the database files are stored is used in RAC Systems.

The need to move OCR and Vote disks to different ASM disk groups arises because we don’t want to be affected by the i / o load in the databases, or we want them to be included in safer disks.

You can follow the steps below to move.
