Restore to Rac Database

 Dear All,

I have an Exadata Marchive X2-2, Half Rack.

I have one database TEST with 4 instances(TEST1,TEST2,TEST3,TEST4).

I have backup database using scrip as below:

$rman target /

RAMN>CONFIGURE CONTROLFILE AUTOBACKUP ON;

RAMN>CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/u01/BAK/%F';

RAMN>CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/u01/BAK/%U' MAXPIECESIZE 2000 M;

RAMN>CONFIGURE DEVICE TYPE DISK PARALLELISM 16 BACKUP TYPE TO BACKUPSET;

RAMN>BACKUP AS COMPRESSED BACKUPSET DATABASE PLUS ARCHIVELOG;

=====================

Alfter backing up database to disk already. I drop it.

Is it posible to restore from backup to Rac Database with 4 instances(TEST1,TEST2,TEST3.TEST4) ?
