3. Install the new disk drives in the upper drive bay. The illustration 
below shows where to install the new drives.

4. From the ok
 prompt, do a reconfigure boot by entering the following 
command:
______________________________________________________
ok boot -r
______________________________________________________
5. Log in as 
root.
6. Enter the following command:
______________________________________________________
#ls -l /dev/dsk/c2t6d0s0
______________________________________________________
The system should respond with a line similar to the following:
______________________________________________________
lrwxrwxrwx 1 roor roor 50 Nov 16 08:58 
/dev/dsk/c2t6d0s0 -> ../../devices/sbus@3,0 
/SUNW,fas@3,8800000/sd@6,0:a
______________________________________________________
Notice that c2t6d0s0 is pointing to sd@6,0:a, indicating that the CD-
ROM drive is now on controller 2.
Step 3: Install the 
mirror disks on an 
Enterprise 3000 
system
2
Do this step only if you have an Enterprise 3000 system.
Install the new disk drives, which will form the mirror, into the empty slots 
reserved in step 1. Follow the procedure in the “Add a Disk Drive” 
subsection in the Lucent Technologies hardware installation or hardware 
maintenance manual for your version of CMS. DO NOT PARTITION THE 
DISKS JUST YET; that happens next.
Step 4: Partition the 
mirror disks
2
Partition the newly installed disks using the format
 command. If you 
have an 
Enterprise 3500, make certain that the new drives are named 
using “c1,” as c1t4d0 or c1t5d0.
The procedure is as follows:
1. Enter: #format
A menu of disks displays. You are asked to select one.
2. Enter the menu number of the new disk to be partitioned.
The format>
 prompt displays.
3. Enter:format> partition
The partition> 
prompt displays.

4. Enter:partition> print
The partition table displays and the partition>
 prompt returns. 
Compare the display to the 
Partitioning table below to see whether 
you need to re-partition the disk. You probably will need to re-
partition.
5. Enter the number of the partition to be reconfigured.
The system begins a series of prompts for partitioning information. 
Answer according to the CMS version and disk type you are 
partitioning (see the 
Partitioning table below).
Repeat this task for each partition on the disk.
6. Enter:partition> print
The partition table displays and the partition>
 prompt returns. 
Compare the display to the 
Partitioning table to make certain you 
have repartitioned the disk properly. If not, repeat step 5.
7. Enter:partition> label
The system responds Ready to label disk, continue? Partitioning (Note: Never change the default size of the 
overlap slice!)

10. To select the next disk to be partitioned, enter:format> disk
and return to item 2.
If you have finished partitioning all the new disks, enter: format> q
and continue with the next step.
Step 5: Create the 
state database 
replicas
2
1. Alter your path by entering the following commands:
2. Create two state database replicas on slice 1 of boot disk 2:
(where 

 is the target number of boot disk 2)
3. Verify that the replicas were created by entering the following 
command:
The system lists the state database replicas currently on the system. 
The following sample output shows two replicas on c0t2:
Make sure the list includes the two replicas you just created.
Step 6: Create the 
md.tab table entries2
1. Make copies of essential system files by entering these commands:
2. Edit 
/etc/opt/SUNWmd/md.tab and insert entries for the root and 
/cms metadevices. If your system is running CMS load r3v6aj.c or 
later, you must also create a section for the 
swap metadevice. # export PATH=$PATH:/usr/opt/SUNWmd/sbin:/olds
# metadb -a -c3 -f /dev/rdsk/

#metadb -i
flags first blk block count
a u 16 1034 /dev/dsk/c0t2d0s1

# cp /etc/opt/SUNWmd/md.tab /etc/opt/SUNWmd/md.tab.orig
# cp /etc/vfstab /etc/vfstab.orig
# cp /etc/system /etc/system.orig

How to upgrade an Enterprise platform to disk mirroring19
The root metadevice definitions go into the #metaroot section, 
which you must create for the occasion; d20 goes into the #/cms 
section, which already exists in the file. The swap metadevice 
definitions go into the #swap section which, like #metaroot, must 
be created for the occasion.
The lines you add must be in the following general format:
d<
x> 1
d is the metadevice name. 
 denotes the total number of disks named in the line.
1 
 indicates one disk with the device name . You 
should have recorded the device names on page 13
. 
The pattern 1 (space) 
 repeats until all disks in the 
metadevice have been named. The d12 entry must specify one disk; 
the d20 entry must specify the same number of disks as the existing 
d19 entry. If your system has two disks in slots 0 and 1 and you are 
adding a two-disk mirror in slots 2 and 3, for example, you would 
add the 
md.tab lines shown in boldface in the following sample: 
-------- /etc/opt/SUNWmd/md.tab - EXAMPLE ONLY --------------
.
.
.
#metaroot
d11 1 1 c0t0d0s0
d12 1 1 c0t2d0s0
d13 -m d11
#/cms

d15 1 1 c0t0d0s4
d16 1 1 c0t2d0s4

-------------------------------------------------------------
3. Save the /etc/opt/SUNWmd/md.tab file and quit the editor.

Step 7: Set up the 
mirrors for the 
root 
file system2
Set up the mirrors for the root file system with the following steps:
1. Activate metadevice d11:
2. Activate metadevice d13:
3. Activate metadevice d12:
4. Attach d12 to d13:
5. Verify that root is set up and resynching:
Check the State:
 lines in the output list. They should read either 
Okay
 or Resyncing
. If they do, then everything is fine. If they 
indicate any other status, something has gone wrong with the setup: 
discontinue the upgrade and telephone the Lucent National 
Customer Care Center (1.800.242.2121) or contact your Lucent 
representative or distributor.# metainit -f d11

6. Edit 
/etc/vfstab. The relevant portion of the file looks like this:
----------------- /etc/vfstab ----------------
...
/dev/dsk/c0t0d0s4 - swap - no -
/dev/dsk/c0t2d0s4 - swap - no -
--------------------------------------------------
Do the following steps to modify the file:
a. Copy the 
c0t0d0s4 entry and insert the copy on the succeeding 
line. 
b. Comment out the original entry by inserting a pound sign at the 
beginning of the line. 
c. Alter the copy by:
1. replacing 
c0t0d0s4 with d17
2. adding md/ after the dev/
d. Immediately after the line just added should be a line naming 
the secondary boot disk. Comment out that line by inserting a 
pound sign at the beginning of the line.
When you have finished 
a through d, the relevant lines of the 
file might look something like this:
----------------- /etc/vfstab ----------------
...
#/dev/dsk/c0t0d0s4 - swap - no -
/dev/md/dsk/d17 - swap - no -
#/dev/dsk/c0t2d0s4 - swap - no -
----------------------------------------------
e. Save the file and quit the editor.
7. Set up the swap space by entering the following command:
# swap -a /dev/md/dsk/d17
#

Step 9: Set up the 
/cms mirror2
1. Edit /etc/vfstab. Copy the d19 entry to the succeeding line. Then 
comment out the original and change “d19” to “d21”. For example: 
---------------- /etc/vfstab - EXAMPLE ONLY -----------------
...
#/dev/md/dsk/d19 /dev/md/rdsk/d19 /cms ufs 2 yes -
/dev/md/dsk/d21 /dev/md/rdsk/d21 /cms ufs 2 yes
-------------------------------------------------------------
2. Save the /etc/vfstab file and exit the editor.
3. Alter your path: 
4. Activate the new metadevice (d20):
5. Verify that d20 is active:
6. Initialize the newly created mirror (d21):
7. Attach the new metadevice (d20) to the newly created mirror (d21):
8. Reboot the system by entering the following command:# export PATH=$PATH:/usr/opt/SUNWmd/sbin:/olds
# metainit d20
d20: Concat/stripe is set up
#
# metastat d20
d20: Concat/Stripe
