Adding new disks to a nonstandard mirrored system
CentreVu CMS Release 3 Version 8 Disk-Mirrored Systems
A "nonstandard" disk drive addition is one that cannot take advantage of
advanced features of the olds setup scripts because the disk
configuration is not standard. The procedure is as follows:
1. Turn off CMS. (From the command line, enter the cmsadm or
cmssvc command, and select the cms_run option. When the run
option menu displays, select Turn off cms.)
2. Halt the system by entering the following command:
# /usr/sbin/shutdown -y -g0 -i0
3. 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 hardware installation or maintenance and
troubleshooting document for your platform and version of CMS.
4. Reboot the system by entering the following command:
ok boot -r
5. Determine the total amount of disk space available to /cms by
entering the following command:
# df -k /cms
The system responds by displaying file system information for /cms.
For example:
Filesystem
/dev/md/dsk/d21
Check the response. Look for the "avail" figure for /cms (shown as
"yyyyyy" in the example above). Record that figure here:
/cms "avail" figure: ______________________
6. Partition the new disks. Follow the instructions in
with the format command" on page
before continuing.
