Changes for HP-UX 11i Version 1.5

The major changes to system crash dump functionality in HP-UX 11i

Version 1.5 are largely internal and do not affect the user-level interface:

❏ The boot loader passes user boot arguments through, unchanged, to

the kernel, where they are parsed. Accordingly, the dump/crash path

handles user boot arguments affecting dump device conﬁguration,

initializes, at boot-time, certain dump-related data structures, allows

for user config(1M)-time and run-time conﬁguration of dump devices

and selection of memory to be dumped, and explicitly passes any

information necessary for the taking of a crash dump to the dump

application.

❏ Dump support is currently available for the Qlogic and LSI SCSI

controllers only.

❏ There is currently no dump support for:

• IDE (you can’t dump to the CD read/write device or the LS-120

ﬂoppy device)

• Fibre Channel

• dump-to-tape
