Netra Proxy Cache Server User's Manual

Appendix A System Recovery

This chapter specifies the procedure for recovery should the hard disk from which you boot fail. You need the Netra Proxy Cache recovery CD to complete the recovery procedure. This CD is shipped with the Netra Proxy Cache product.

Note -

A nearly indispensable aid to the recovery of a Netra Proxy Cache Server is the backup diskette you were instructed to create in the Netra Proxy Cache Server Configuration Guide. If you do not have such a diskette, you can still recover, but you must repeat some of the configuration steps described in the Netra Proxy Cache Server Configuration Guide.

The installation program on the recovery CD performs the following steps:

Installs the Solaris operating environment

Formats your hard disks and installs the partition map appropriate for a Netra Proxy Cache Server

Installs the Netra Proxy Cache product packages

Package Restoration

To Restore the Solaris Operating Environment and Netra Proxy Cache Packages

Replace the hard disk, following the procedure specified in the Netra Proxy Cache Server Service Manual.

Ensure that you have a terminal connected to your Netra Proxy Cache Server, as described in Appendix A of the Netra Proxy Cache Array Configuration Guide or Netra Proxy Cache Server Configuration Guide.

With your Netra Proxy Cache Server connected to both service and control networks, power up your server.

Insert the Netra Proxy Cache recovery CD in the server's CD drive.

Send the RS232 break signal to obtain the ok prompt.

For tip use:
```
<return>~#
```
For telnet, use Ctrl-]. For other programs, use the appropriate break signal.

At the ok prompt, enter:

ok boot cdrom

The Solaris boot process starts. The following prompt is displayed:

Please confirm that you want to reinstall Netra Proxy Cache 1.0.
This will ERASE ALL EXISTING DATA on the system. 

Answer yes, no or quit: y

Enter y to the preceding prompt.

The entire process takes about an hour. The process completes when the server returns to the ok prompt.
