Make sure that the source disk and destination disk have the same disk geometry.
Become superuser or assume an equivalent role.
Create the /reconfigure file so the system will recognize the clone disk to be added when it reboots.
# touch /reconfigure |
Shut down the system.
# init 0 |
Attach the clone disk to the system.
Boot the system.
ok boot |
Copy the master disk to the clone disk.
# dd if=/dev/rdsk/device-name of=/dev/rdsk/device-name bs=block-size |
if=/dev/rdsk/device-name |
Represents the overlap slice of the master disk device, usually slice 2. |
of=/dev/rdsk/device-name |
Represents the overlap slice of the clone disk device, usually slice 2. |
bs=blocksize |
Identifies block size, such as 128 Kbytes or 256 Kbytes. A large block size value decreases the time it takes to copy. |
For more information, see dd(1M).
Check the new file system.
# fsck /dev/rdsk/device-name |
Mount the clone disk's root (/) file system.
# mount /dev/dsk/device-name /mnt |
Edit the clone disk's /etc/vfstab to reference the correct device names.
For example, change all instances of c0t3d0 with c0t1d0.
Unmount the clone disk's root (/) file system.
# umount /mnt |
Shut down the system.
# init 0 |
Boot from the clone disk to single-user mode.
# boot diskn -s |
The installboot command is not needed for the clone disk because the boot blocks are copied as part of the overlap slice.
Unconfigure the clone disk.
# sys-unconfig |
The system is shut down after it is unconfigured.
Boot from the clone disk again and provide its system information, such as host name, time zone, and so forth.
# boot diskn |
Log in as superuser to verify the system information after the system is booted.
hostname console login: |
This example shows how to copy master disk /dev/rdsk/c0t0d0s2 to clone disk /dev/rdsk/c0t2d0s2.
# touch /reconfigure # init 0 ok boot # dd if=/dev/rdsk/c0t0d0s2 of=/dev/rdsk/c0t2d0s2 bs=128k # fsck /dev/rdsk/c0t2d0s2 # mount /dev/dsk/c0t2d0s2 /mnt # cd /mnt/etc # vi vfstab (Modify entries for the new disk) # cd / # umount /mnt # init 0 # boot disk2 -s # sys-unconfig # boot disk2 |
