To back up the disk unit, use the dd(1M) command after booting from the Solaris OS CD/DVD.
If you are restoring, use the dd(1M) command after booting from the Solaris OS CD/DVD to
restore the disk unit.

It is recommended that you select the SCSI device with target ID 1 for Solaris OS installation. Before
selecting the disk to install Solaris OS, make sure it is connected to the SCSI adapter plugged into the PCI
slot of PCI0B. In this case, the device name of the system disk will be "c0t1d0" (obtained from the
controller number (0), target ID (1), and LUN number (0)). If you install Solaris OS to other than the disk
having the device name "c0t1d0", (especially, a disk having the controller number other than 0) take care to
carefully obtain the correct device name.
If applying the optional software that runs as part of the driver and file system from the system disk,
carefully follow the instructions and notes described in the manual of each option. For example, if you
configure disk mirroring using PRIMECLUSTER GDS, you must select the backup procedures described in
a. above, because the PRIMECLUSTER GDS driver does not exist in the CD/DVD files. In addition, if the
system disk contains a file system other than the ufs file system such as PRIMECLUSTER GFS, select the
backup procedures using the backup command provided in the file system or the dd(1M) command.

If you back up slice 0, it will only be possible to restore to a disk having the same physical
properties (such as disk space and a number of cylinders) as the original.
Disk partition information such as the size of each slice will not be backed up. You must record
the information separately.
The procedure divides the disk unit for back up, so it is only possible to restore to a disk having
the same physical properties (such as disk space and a number of cylinders) as the original.
