How to upgrade an Enterprise platform to disk mirroring 12
Increasing system
capacity
2
If you intend to increase your system capacity as well as mirror your
system, first install the new disks needed to increase capacity. For
instructions, see the documentation that came with the new drives or the
appropriate Lucent Technologies installation documents. After the system
capacity has been increased, and it has been verified that the system
works correctly, you may then install disk mirroring. You must make
certain the basic system works before you try to mirror the disks.
Step 1: Identify
mirror devices
2
1. Check the number of new disks to be installed as the mirror.
There should be as many new disks to be installed as there are old
disks already on your system. That keeps the same system capacity
and makes the two submirrors the same size.
2. Next you must identify the device names for your mirrored system
and record them in the
Device/Metadevice Names
table on the next
page.
If you have an
Enterprise
3500 system, the device names have
already been identified and recorded for you in the
Enterprise
3500
table. Here’s how you identify the device names for an
Enterprise
3000 system:
a.
Identify the secondary boot disk and record the device
names.
Find the first empty slot in your system. Whatever slot you find
will hold the secondary boot disk. Then record the following
device names for that disk:
●
Record the slice 0 device name as submirror 12.
●
Record the slice 3 device name as disk 1 of submirror 20.
●
If your system is running load r3v6aj.c or later of CMS—
you can find out by executing a
pkginfo -x cms
command—record the slice 4 device as submirror 16.
Example: If the first empty drive slot in your system were
slot 2, you would record the following values in the table:
Submirror d12
Device Name
. . .
Submirror d20

boot disk (2):
