guest100, hmmm, I see you're right. That ability to specify a dump number doesn't exist on HP-UX and I never noticed it on Solaris. On both OS's I do restores the way I said, I fsf first to the proper file then do the restore.
Severd_Nerd, I don't understand at all what you are talking about.

Hi all,
Sometimes, when I reboot my AIX server, my tape drive /dev/rmt# assignments change. This creates some tedious TSM work prior to and after a reboot of the server.
Is there a way to ensure that the /dev/rmt# assignments come up the same every time?
Thanks (5 Replies)

siglongjmp
LONGJMP(3) Library functions LONGJMP(3)
NAME
longjmp, siglongjmp - non-local jump to a saved stack context
SYNOPSIS
#include <setjmp.h>
void longjmp(jmp_buf env, int val);
void siglongjmp(sigjmp_buf env, int val);
DESCRIPTION
longjmp() and setjmp() are useful for dealing with errors and interrupts encountered in a low-level subroutine of a program. longjmp()
restores the environment saved by the last call of setjmp() with the corresponding env argument. After longjmp() is completed, program
execution continues as if the corresponding call of setjmp() had just returned the value val. longjmp() cannot cause 0 to be returned. If
longjmp is invoked with a second argument of 0, 1 will be returned instead.
siglongjmp() is similar to longjmp() except for the type of its env argument. If the sigsetjmp() call that set this env used a nonzero
savesigs flag, siglongjmp() also restores the set of blocked signals.
RETURN VALUE
These functions never return.
CONFORMING TO
POSIX
NOTES
POSIX does not specify whether longjmp will restore the signal context. If you want to save and restore signal masks, use siglongjmp.
longjmp() and siglongjmp() make programs hard to understand and maintain. If possible an alternative should be used.
