Disk Mirroring 343
Adding a Mirror Disk If your system uses a single disk, you can add a mirror disk. The disk you
add must have at least the same storage capacity as the disk in the
system. You must obtain a disk mirroring license to convert a single-disk
system to use disk mirroring. You need a Phillips screwdriver to complete
this process.
CAUTION: Adding a mirror disk involves a system database backup and a
system shutdown. 3Com advises that you add a mirror disk only during
non-business hours.
