Adding new disks to a standard mirrored system		65

13.Add the new disks to the existing metadevices by entering the following command:

# olds -mirrored -setup <newdisk1> <newdisk2>

(where, again, <newdisk1> and <newdisk2> are the device names of the disks you have added).

The system responds with the following:

Warning: Current Disk has mounted partitions.

device: c0t6d0	will not be		used
. . .
d19: component	is attached
d20: component	is attached
. . .
d21: submirror	d20	is attached
Success, growing		d21
Success, the	capacity of		the /cms mirror has increased.
#

14.Restart CMS by entering the cmsadm or cmssvc command and selecting the cms_run option. When the run option menu displays, select start cms.

15.Check the available disk space by entering a df -kcommand. For example:

# df -k
Filesystem	kbytes	used	avail capacity		Mounted on
/dev/md/dsk/d13	772038	538683	156155	78%	/
/proc	0	0	0	0%	/proc
fd	0	0	0	0%	/dev/fd
/dev/md/dsk/d21	3059955	192497	4967458	7%	/cms

Compare the avail figure for /cms to the figure you recorded in Step 8; it should show an increase roughly equal to one-half of the total capacity of the drives added.
