Dumping System Memory and Secondary Storage

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.

Execution of this command irrecoverably halts all system processing and

I/O activity and restarts the computer system.
