Adding new disks to a standard mirrored system 3
The procedure in this section adds new disks to a system that is already
mirrored. In order to use this procedure, your assigned boot disks must
be the same as those assigned during a factory installation of disk

arrangement (see the table immediately below), you must add the disks
using the procedure in “Adding new disks to a nonstandard mirrored
system” on page 66.
