Increasing system capacity
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
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
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
boot disk (2): c0t2d0s0
Submirror d16 Device
(r3v6aj.c or later)
swap c0t2d0s4
. . .
Submirror d20
Device Names
CMS disk 1: c0t2d0s3
