Doing a CMSADM backup on a mirrored system

This section describes how to perform a traditional CMSADM backup on a mirrored system.

Step 1: Print the vfstab file

NOTE:

Mirroring is intended as a way to minimize data loss should a system crash occur, not as a way to avoid backing up data. Mirrored systems must be backed up just as often as unmirrored systems.

Print out the contents of the vfstab file before beginning the backup. You will need the information in that file to restore files from the backup tape.

To print the vfstab file, do the following:

1. Enter the following command:

# lp /etc/vfstab

Step 2: Run the backup

2.Retrieve the printout and save it. You will need it again when the backup finishes.

1.At the system console, log in as root.

2.Verify that the computer is in a Solaris multi-user state (a run level of 2 or 3) by entering a who -rcommand. The system responds by listing the run level and date. For example:

#who -r

. run-level 3 Feb 2 16:52 3 O S

#

If the system is in some other run level, reboot and log in again as the root user:

#/usr/sbin/shutdown -y -g0 -i6

. . .

<hostname> login: root

password: <password>

. . .
