Itanium or PA-RISC? Which model?

Basically, you must have access to the console of the server you're booting. After the hardware tests, you have a chance to stop the automatic reboot. It will display something like "press any key in 10 seconds to stop autoboot".

After that, you can use the commands of the BCH (Boot Console Handler) to select which media you wish to boot from.

To boot from a tape, the usual method is to first search for bootable devices. The command for that is "search" (you need to type just "sea"). It will produce a list of disk, tape and CD/DVD devices. A tape drive is listed as "sequential-access device".

The first detected bootable device will be given the shorthand P0, the next P1 and so on. For example, if P0 and P1 are the internal hard disks and P2 is the tape drive,
you can boot from the tape with command "boot p2". It can be shortened to "bo p2" if you don't want to type all of it.

thank you Matti Kurkela that was realy valuable informations but i need to now 1 more thing: the AUTOBOOT variable is set to YES, so does this variable affects interruptability of the boot sequance?

The answer is that it will not effect interupting the boot sequence!
