Oracle RAC backup and recovery Voting Disks

The Voting Disks file does not need to be backed up every day. Generally, backup is required in the following situations:

①: After Clusterware is installed.

②: After adding and deleting nodes in the cluster.

③: After the Voting Disk add or delete operation is executed.

Example of backing up voting Disk:

Environment:

[Oracle @ node2 ~] $ Uname-
Linux node2 2.6.18-164. el5 #1 SMP Tue Aug 18 15:51:54 EDT 2009 i686 i686 i386 GNU/Linux

SQL> select * from v $ version;
