Cluster Platform 15K/9960 System Recovery Disks

The recovery disks enable you to replace the factory-installed Cluster Platform 15K/9960 software environment on the management server in the event of a system disk failure.


Contents of the Recovery Disks

The Cluster Platform 15K/9960 system media kit contains a bootable CD and a recovery DVD that are used for restoring the system software. The DVD contains the following software:


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 Cluster Platform 15K/9960 System Site Planning Guide.

Your system configuration information must include the following:



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.




procedure icon  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 admin station as the superuser.

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

# telnet terminal_concentrator_name 5001

3. In the console window, press Ctrl+] to enter the telnet command mode, as indicated by the telnet> prompt.

4. Use the following command to access the OpenBoottrademark PROM prompt:

telnet> send brk

5. Insert the Installation CD into the DVD-ROM drive.

6. Boot the system from the CD:

ok boot cdrom

The system will prompt you for the Solaris installation information.

7. Press 1 for initial install.

8. Type Y to format the boot disk.



Code box showing the disk format prompt.

Caution - In this procedure, you are not performing a generic Solaris software installation. You must ensure that you format the boot disk properly. Do not accept the default formatting scheme.



The default root disk is /dev/dsk/c1t0d0.
The Solaris installer needs to format 
/dev/dsk/c1t0d0 to install Solaris.
 
WARNING: ALL INFORMATION ON THE DISK WILL BE ERASED!
 
Do you want to format /dev/dsk/c1t0d0?  [y,n,?,q]: y
 
NOTE: The swap size cannot be changed during filesystem layout.

9. Enter the swap slice size.

Enter a swap slice size between 352MB and 34729MB, default = 512MB [?] 1024

10. Press N when prompted to begin the swap slice at the beginning of the disk.

The Installer prefers that the swap slice is at the beginning of the
disk. This will allow the most flexible filesystem partitioning later in the installation.
Can the swap slice start at the beginning of the disk  [y,n,?,q] n

11. Press 1 when prompted to place the swap slice at cylinder 0.

WARNING: Placing the swap slice at a cylinder location other than cylinder 0 requires expert knowledge about disk layout. This choice may affect disk layout choices later in the installation.
 
Enter a starting cylinder between 0 and 24257, default = 0 [?] 1

12. Press Y to confirm the choices.

You have selected the following to be used by the Solaris installer:
 
        Disk Slice  : /dev/dsk/c1t0d0
        Size        : 1024 MB
        Start Cyl.  : 1
 
WARNING: ALL INFORMATION ON THE DISK WILL BE ERASED!
Is this OK  [y,n,?,q] y

The system is rebooted at this point. Then, the Solaris WebStart installation begins.

13. Answer the WebStart questions as in the following example.

Some of the information that appears between the user input lines have been left out to simplify the example.

Consult your network administrator about specifying a naming service. If you use a name service, you must modify the /etc/nsswitch.conf file on the management server so that "files" appears before any other name service.



Note - The two cluster nodes are automatically configured not to support a naming service. This default configuration avoids the need to rely on external services:

Enter 'y' to layout file systems on the specified disk.  This will erase all
existing data on the disk.  Enter 'n' to leave the disk unmodified.
   Layout file systems on disk c1t0d0 (bootdisk) (y/n) [y]? y
Layout file systems on disk c1t1d0 (y/n) [n]? n
 
The Solaris Installer is determining size requirements based on your choices, please wait...
The swap partition was not created on the first available cylinder. This is
required for autolayout. Manual layout of the filesystems is required. This
layout must be done on the cylinder level.

Completing the Recovery Process

After the management server software image is restored, you must configure the system to match your environment. Refer to the Cluster Platform 15K/9960 System Installation Guide for information on how to customize the management server.
