Indicates a data comparison fault. For 3.5x
version software (and later), the system
automatically adapts for data mismatches
and unequal hard disk capacity. The system
attempts a disk mirror rebuild.
The system continues to operate. Nortel
recommends that you perform the following:
•
Examine the status report to determine
which hard disk has the smaller capacity.
•
Replace the smaller hard disk (primary
master or mirror master) with a new hard
disk of the correct size. Equipment
provided by Nortel assures correct hard
disk capacity requirements.

•
Drives are not in mirror mode.
•
Missing or bad hard disk (1 or both).
•
Occurs on newly installed RAID card
or hard disk (first 10 min). SSM
begins mirror process — no action
required.
•
SSM determined BCM is not
initialized (core software, WAN,
MSC).
Immediate action required:
•
Check the RAID operational status.
•
Check hard disk power and data
connections.
•
Replace the hard disk if required.
•
Initialize the BCM system.
