One thing I would recommend is to add additional LUN's for voting disk
and OCR. In the past we did not mirror ocr or voting disks, and this
has been found to be a mistake so we changed our standard build policy
to include these mirrors. Make sure to have at least 2 LUN's for voting
disk, and 2 LUN's for OCR and mirror then via Oracle. Each uses less
than 1gb of space (usually less than 100mb each but we provision at 1gb
as that is the minimum size for LUN's for our SAN).
And to reiterate what others have said- hardware mirroring / raid is
faster than software mirroring.
