Restoring a snapshot
Prerequisites
Perform the following steps for before restoring a read/only snapshot:
Ensure that you stop all the Remote copy groups before initiating a snapshot restore operation.
Ensure that you dismount the database ASM disk groups from one or more cluster nodes. Also, ensure that you drop the disk groups from one of the cluster nodes server if ASM is in use when you do not select the Automate Restore option.
Ensure that you unmount all the database file systems from the database server if they are on file systems. For example,
# umount /oradata
- Ensure to export the database volume groups from the database server if volume groups are in use. For example, for Linux logical volume groups:
# lvchange -an /dev/rh6lvm-data/lvol0 # lvchange -an /dev/rh6lvm-data/lvol1 # vgexport rh6lvm-datavg
Ensure that you remove the volumes exported as physical Raw Device Mapping from Oracle server for databases with volumes exported as physical RDM.
