Adding new disks to a nonstandard mirrored system

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	kbytes	used	avail	capacity	Mounted on
/dev/md/dsk/d21	xxxxxxxx	9	yyyyyy	0%	/cms

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 “Partitioning disks with the format command” on page 76. Double check the partitioning before continuing.
