Adding new disks to a standard mirrored system
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 mirroring. If your boot disk assignments differ from the standard factory 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.

New Enterprise 3000 internal disks are “hot swappable,” meaning they can be inserted into a running system. The operating system, however, will not recognize the new disks until the system has been rebooted.
1.Enter the command:
# /usr/opt/SUNWmd/sbin/metastat
Examine the output for the status of each metadevice. (It’s indicated in the Status:.... line.) All metadevices must have a status
of okay before you may proceed. Do not attempt this procedure while any metadevice is resynching or needs maintenance.
