Restore and recovering a rac database

Hi,

I need to restore a RAC database and usually i do the restore and recovery by starting only 1 instance. However i would like to know if i can take advantage of 2 nodes to speed up the restore/recovery and will this approach work and is suggested or not? At a high level, my restore and recovery looks as below.

Please let me know

1. catalog the rman backups

2. start both the db instances with cluster_database set to true

3. restore controlfiles

4. Mount the instances Restore/recover as below

set echo on

connect target /

run {

ALLOCATE CHANNEL C1 DEVICE TYPE DISK CONNECT sys/password@node1_alias;
