No action required. As the disks are partitioned and the system 
files are copied to the disk, the progress gauge is updated to 
indicate the progress of the installation, and takes about 40 
minutes to reach 100%. At that point the progress window 
disappears. A console window appears in the upper left corner 
of the screen and the installation continues. The remainder of 
the installation can take several hours, depending upon the

Step 11: Complete 
the OS installation

This procedure completes the operating system installation.
Step 12: Alter the 
tape configuration 
file (
Enterprise 
3500 only)
3
If you are running on a Sun Enterprise 3500 platform, you must alter the 
/kernel/drv/st.conf file so the operating system recognizes the 3500’s 
8mm tape drive. To accomplish that, do the following steps:
1. Start an editor such as vi or the CDE Text Editor, and load the 
/kernel/drv/st.conf file.
2. Find the #tape-config-list= 
line. It should be in the vicinity of 
line number 40.
3. Insert, immediately before that line, the following:
4. Save the file and exit the editor. Task Action Result

Restoring specific files from a CMSADM backup62
Restoring specific files from a CMSADM backup3
To restore specific files from CMSADM backup tapes, enter the following 
commands at the system prompt (for example):
(where 
 is the full path name of the file to be restored)
Note the device name in the example 
(/dev/rmt/0c). That name is usually 
correct. Some other device name may be required, however, depending 
upon the drive’s SCSI ID and compression capability. Tape device names 
are as follows:
/dev/rmt/0
The internal, noncompressing tape drive (14-GB, 
8-mm drive) with the lowest target address.
/dev/rmt/1
The external, noncompressing tape drive (QIC-150 
or 5-GB, 8-mm drive) with the second lowest target 
address.
/dev/rmt/0c
The internal, compression-capable tape drive 
(usually a 14-GB or 40-GB) with the lowest target 
address.
/dev/rmt/1c
The external, compression-capable tape drive 
(either a QIC 2.5-GB or a 14-GB tape drive) with 
the second lowest target address. #cd/
# cpio -icmudv -C 10240 -I /dev/rmt/0c -M “Please 
remove the current tape, insert tape number %d, and 
press ENTER”

Adding new disks to a standard mirrored system63
Adding new disks to a standard mirrored system3
The procedure in this section adds new disks to a system that is already 
mirrored. In order to use this procedure, your assigned boot disks must 
be the same as those assigned during a factory installation of disk 
mirroring. If your boot disk assignments differ from the standard factory 
arrangement (see the table immediately below), you must add the disks 
using the procedure in “Adding new disks to a nonstandard mirrored 
system” on page 66. 
New 
Enterprise 3000 internal disks are “hot swappable,” meaning they 
can be inserted into a running system. The operating system, however, 
will not recognize the new disks until the system has been rebooted.
1. Enter the command:
Examine the output for the status of each metadevice. (It’s indicated 
in the Status:.... 
line.) All metadevices must have a status 
of okay 
before you may proceed. Do not attempt this 
procedure while any metadevice is resynching or needs 
maintenance.
2. Do a CMSADM backup. For detailed instructions, see the Lucent 
Technologies Administration or Upgrades document for your version 
of CMS.
3. Turn off CMS:
a. Enter a cmsadm 
or cmssvc 
command.
b. Select the cms_run
 option.
c. Select the Turn off cms
 option.
4. Halt the system:
5. Install the new disk drives by plugging them into the appropriate 
empty drive slots. Follow the instructions you received with the disk 
drives or with your basic system, or see the Lucent Technologies 
installation or maintenance document for your version of CMS.Boot-Disk Assignments for Factory-Installed Mirroring

Adding new disks to a standard mirrored system64
6. Reboot the system and log in as the root user:
7. Partition the new disks by following the instructions in “Partitioning 
disks with the format command” on page 76.
8. Check disk space by entering a df -k 
command. For example:
Record the 
avail figure for /cms here: ______________________
9. Create new versions of the setup files by entering the following 
commands:
 and  represent the device names of the 
disk drives added (remember that in a mirrored system, disk drives 
are always added in pairs). For example:
10. Load the file 
/etc/opt/SUNWmd/md.tab.new into an editor and make 
certain it names all
 of your disks, including the ones you just added. 
(For an example of the md.tab file format, see “Examples of valid 
system files” on page 79.)
11. Save a copy of the existing 
md.tab file by entering the following 
command:
12. Replace the existing 
md.tab file with the one you created in Step 10: ok boot -r
