Backing up/restoring the SMC Functions of the System Management Console

4.5.2 System drive

4.5.2.1 Backing up the system drive of the SMC

This section describes how to back up offline.

When the system drive is backed up, all data saved on the hard disks which are installed in

the SMC is transferred onto DAT data cartridges.

With this procedure, you can back up the data stored on all hard disks. This procedure is

particularly useful for exchanging a faulty hard disk, since you can transfer all data backed

up on the data cartridges onto the new hard disk. The system then regains the configuration

which was valid at the time the backup was created.

This process, during which the data on all hard disks is written onto data cartridges, takes

approximately one hour. All console functions are deactivated whilst the data is being

saved.

The volume of data to be saved is so large that only DDS4 data cartridges (150 m)

should be used.

Before you start the backup, check the amount of data stored on the hard disk.

To back up the data on the system drive, you will need:

– One DAT data cartridge, DDS4, 150 m

– The CD-ROM (1 of 2) with the Solaris software for the SMC

Proceed as follows to create a backup of the system drive:

1. Log on at the SMC as root.

2. Switch to OBP mode by entering the following command:

SMC# /usr/sbin/shutdown -g0 -y -i0

3. Insert the Solaris CD-ROM in the CD-ROM drive.

4. Insert a data cartridge in the DAT drive. Check beforehand that the cartridge is not write-

protected, i.e. that the write protection slider is set at “writeable”.

5. Start Solaris in single-user mode from the CD-ROM:

ok boot cdrom -s
