Re: Veritas CFS or QFS ? Which for High Hybrid Transaction Load Benchmark on RAC with Solaris 10/Oracle 10g ?

Simply use rman to restore your datafiles to raw volumes.

The most min-downtime solution is;
build a standby on the raw volume on rac, do a switch over, and your databsae is running in rac mode within 10 minutes.

You can take anytime you desire to make your standby database onto the raw volume.
