Escalating the Shutdown Operation

If you choose the ORDERLY or ABORT option, you can escalate the shutdown

operation by pressing the Break key and then specifying a faster option.

For example, if you specify ORDERLY, but find that you require a faster shutdown, you

can press the Break key and then specify either the ABORT option or, for fastest

shutdown, the IMMEDIATE option, as shown in this example:

= SHUTDOWN2, MODE ORDERLY Shutdown begins.

You decide to escalate the

shutdown operation, so you press the

Break key.

= The PATHCOM prompt returns.

= SHUTDOWN2, MODE IMMEDIATE You specify the SHUTDOWN2, IMMEDIATE

command for the fastest shutdown

possible.

= Once the shutdown operation completes,

the PATHCOM prompt returns.

You can also specify a TIMEOUT option that helps you escalate SHUTDOWN by

returning the PATHCOM prompt within a specified time period. This command

specifies a five-minute timeout option:

= SHUTDOWN2, MODE ORDERLY, UNTIL TIMEOUT 5 MINS

If the shutdown operation has not completed after five minutes, the PATHCOM prompt

returns while the shutdown operation continues.

The TIMEOUT option is especially useful if you want to escalate the shutdown

operation from within a command file or TACL routine.

Monitoring Shutdown Status

You can monitor the status of the shutdown in one of two ways:

•

Include the STATUS AGGREGATE option in your SHUTDOWN2 command, as

shown in this example:

= SHUTDOWN2, MODE ORDERLY, STATUS AGGREGATE, UNTIL TIMEOUT

5 MINS

The STATUS AGGREGATE option tells PATHCOM to display shutdown status

every 20 seconds until shutdown completes or until the TIMEOUT option (if

specified) expires.

Note. Pressing the Break key does not affect the execution of the shutdown process. It simply

returns the PATHCOM prompt to your terminal so that you can enter other commands: for

example, STATUS PATHWAY or a more forceful SHUTDOWN2 option. For more information,

see Using PATHCOM During Shutdown on page 2-21.
