Clustered Database Software 1.0 Recovery Disks

The recovery disk enables you to replace the factory-installed Clustered Database software 1.0 software environment on the management server in the event of a system disk failure.

Contents of the Recovery Disks

The Clustered Database software 1.0 media kit contains a bootable CD and a recovery DVD that are used for restoring the system software.

Note - You must also use the recovery DVD from the hardware media kit.

The DVDs contain the following software that is installed on the management server:

Solaris 8 10/01 operating environment

Solaris DiskSuite 4.2.1 software with patches

Sun Cluster 3.0 software with the appropriate patches

Solaris JumpStart software environment

Sun Management Center 3.0 update 4 with help desk

Sun Component Manager software

SunRay Server 1.3 software

AnswerBook2 1.4.4 software

Apache 1.3 server software

Enterprise Services Explorer 3.5

Before You Use the Recovery Disks

Before you attempt to restore the management software environment, you must know your system configuration information and the state of your system backups. For information about the configuration, refer to the site-planning guide or installation guide for the hardware.

Note - When you installed the management server for the first time, you should have created a back-up copy of the /jumpstart/Files/JumpStart.conf file. After you recover the management server, you must install the backup copy of the /jumpstart/Files/JumpStart.conf file to restore the system variables.

Using the Recovery Disks

This section includes procedures for recovering the management server. The recovery disks are intended only for recovering from a disaster. Do not use the recovery disks for installation and configuration of the management server or cluster nodes.

Caution - Initiate a recovery only at the direction of technical support. Because the recovery results in a generic, unconfigured system, you must restore all site-specific configuration files from backup data.

To Use the Recovery Disks

The following procedure contains examples of the output from the recovery scripts. Certain values such as IP addresses and host names are examples only. Your system will have different values.

1. Log in to your administration station as superuser.

2. Use the following command to access the management server console through the terminal concentrator:

# telnet terminal_concentrator_name

3. Press Return when you are prompted for the escape character.

4. Enter the Annex port name or number.

5. In the cluster console window, press Ctrl+] to stop the cluster nodes.

6. Use the following command to access the OpenBoot trademark PROM prompt:

telnet> send brk

7. Insert the bootable installation CD into the DVD-ROM drive.

8. Boot the system from the CD:

ok boot cdrom

You will see the following output.
