Entering the DUMP Utility and Starting the System

A procedure for performing a dump and booting a system includes the following steps:

1. Mount a tape on the tape drive.

2. Soft reset the system using the access port method, boot from the primary path, and

enter the DUMP command at the ISL prompt.

NOTE If you have a 99X system, you must transfer to the service processor before

you can soft reset the system.

CAUTION Do not issue the RS command from the console or push the RESET button on

the front panel. Hard resetting the system initiates a destructive processor

self-test that invalidates dump data.

CAUTION There will be a one- to two-second delay between typing TC and getting the

message Processor Dependent Code (PDC) revision X.X. During this

time no keys should be pressed on the console.

The system prompts for a user identiﬁcation string and for the correct date and time

shortly after receiving the DUMP command. The user can enter up to 80 characters,

which can later be displayed by DAT when analyzing the dump. There is a 60-second

timeout on this prompt. Once a key is pushed on the console keyboard, the timeout is

aborted and a carriage return is required to continue with the dump. If a key is not

pushed within 60 seconds, the prompt times out, and the dump proceeds with a blank

user dump ID in the label. If the date and time are correct, press

Return at the date

prompt. If the date or the time are incorrect, respond as requested with the correct date

and time in 24-hour format.

NOTE The DUMP procedure shown in Example 3-7 was performed on an N-Class

system. The procedure assumes that autoboot is enabled. Make necessary

adjustments to the procedure if autoboot is disabled on your system.

Sequences from other installations may vary.
