How to force a crash dump

[ISS Unix Admin]

I need to test the crashdump & savecrash configurations.

How can I force a crashdump on an L-2000/2/440?

Thanks

If you go into the GSP area of the system, somewhere in there is an option for TOC.

First be REAL SURE you want to do this, as theres's not much difference between doing this and just pulling out the mains lead.

Go to the console and press CTRL-B

Assuming no user accounts have been set up in the GSP just hit return twice to skip the login.

AT the GSP prompt enter TC

I seem to remember it will check you are sure you want to proceed.

Some older systems (e.g. D class) also have a 'Transfer of Control' button on the back - can't remember ever seeing one on an L or N class though.

Before you do this GET A FULLBACKUP OF THE SYSTEM!

Heaven forfend that you do this and find that your system will not pass muster with fschk. This could lead to a reload and if your backup tapes are missing a days worth of data.............well, is your resume up to date?

One more thing.....

It IS under GSP on the L-class and the difference between RS and TC is as follows:

RS wipes RAM clean before rebooting
TC preserves RAM for saving to tape

use the wrong one and wave bye-bye to the contents of your memory.
