Note: RAID disk mirroring takes up to 3 hours to complete. The BCM system continues
to operate normally during the disk mirroring process. However, because disk mirroring
occupies computing resources, Nortel recommends that you perform disk mirroring during
a period of low call traffic.
Note: If this is the first time installation of the RAID configuration, both primary and
mirror Status LEDs are green.
