Chapter 4: Restoring System Software

Using a Disaster

Recovery Tape

This section contains:

■ Introduction, 4-3

■ Prerequisites, 4-4

■ Material Required, 4-4

■ The Disaster-Recovery Process, 4-4

Introduction

Use of these instructions can be avoided by maintaining

system recovery tapes for your system(s).

A disaster recovery tape can be used to restore a system

when a system recovery tape is not available.

If a disaster recovery tape is used, you will be required

to re-establish both the /etc/bootptab and

/hp3070/diagnostics/th1/config files. If these two

files are not available (from a backup source), it will

likely be necessary to contact your Agilent systems

engineer (SE) to re-establish them.

CAUTION

✸

In the case of a system disaster, the cost and time

required to obtain an Agilent SE could be avoided

if you maintain a separate backup of the

/etc/bootptab and

/hp3070/diagnostics/th1/config files.

However, the need for a separate backup of these

two files should be eliminated by following a

practice of maintaining system recovery tapes for

your system(s); if you maintain system recovery

tapes, use of a disaster recovery tape should never

be necessary.

Disaster-recovery tapes are available from Agilent.

They are manufactured to bring a 3070 system to a

specific working revision of 3070 software.

Use these instructions if a system recovery tape does not

exist AND either:

■ A system disaster has occurred such as a disk

crash OR

■ A replacement disk drive has been installed.
