Maintaining Mirrored Systems	CentreVu CMS Release 3 Version 8 Disk-Mirrored Systems
Adding new disks to a standard mirrored system		64

6.Reboot the system and log in as the root user:

ok boot -r

. . .

<hostname> login: root

password: <password>

. . .

#

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 -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	2867458	7%	/cms
#

Record the avail figure for /cms here: ______________________

9.Create new versions of the setup files by entering the following commands:

#cd /olds

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

<newdisk1> and <newdisk2> represent the device names of the disk drives added (remember that in a mirrored system, disk drives are always added in pairs). For example:

#olds -mirrored -mk_files c0t10d0 c0t11d0

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:

#cp /etc/opt/SUNWmd/md.tab /etc/opt/SUNWmd/md.tab.mirror

12.Replace the existing md.tab file with the one you created in Step 10:

#cp /etc/opt/SUNWmd/md.tab.new /etc/opt/SUNWmd/md.tab
