In Oracle Database 10g Release 1 the OCR and Voting device are not mirrored within Oracle,hence both must be mirrored via a storage vendor method, like RAID 1.Starting with Oracle Database 10g Release 2 Oracle Clusterware will multiplex the OCR and Voting Disk (two for the OCR and three for the Voting).Please read Note:279793.1 and Note:268937.1 regarding backup and restore a lost Voting/OCR and FAQ 6238 regarding OCR backup.
