Introduction
The Sun Enterprise 450 and the Sun Fire V445, V880, and V890 DNCS
platforms support disk mirroring. Through disk mirroring, the DNCS
stores identical information across sets of hard drives. System
operators and support engineers who perform maintenance operations
on a Sun Enterprise 450 or the Sun Fire V445, V880, and V890 DNCS
may first be required to disable the mirroring functions on the DNCS.
Then, after the maintenance operations are complete, the mirroring
functions must be re-enabled.
