Background: In the operation manual, the chapter about disk mirroring of the N2000 BMS
V200R008 only describes how to perform disk mirroring with two disks on Solaris 8 OS. It does
not describe how to perform disk mirroring with four disks.
The N2000 BMS V200R011 provides scripts for mirroring the first and second disks to the later
two disks on Solaris 10 OS. But how can you mirror the first disk to the second one and the
third disk to the fourth one?
This case describes how to perform disk mirroring flexibly.
Note: This case considers the SUN V440 as an example and describes how to perform disk
mirroring with four disks to separately mirror the used disks (disks and ) to disks and . Close the
N2000 BMS and the Sybase database, install the disk mirroring software — DiskSuite4.2.1, and
then run the disk mirroring scripts.
Section 1 Mirroring Partitions
Run the root@N2000Server # df -k command to query partitions. The partitions are as follows.
Filesystem
/dev/dsk/c1t0d0s0 37183076 18469581 18341665 51% /
/dev/dsk/c1t0d0s3 10327372 6231083 3993016 61% /opt

Note: The first disk has three partitions. Root partitions /, opt/, and /export/home are installed
