hello,
i had the same problem, i fixed it with a little startup script.
First try to:
Reboot the HP - UX machine. (keep ur storage running)
then it wont find the Fibre Channel Disks.
Try just an IOSCAN.
and then look with ioscan -funC disk if the Storage Disks are available.
If they are available after a ioscan and you are able to do a vgchange -a y vgxx, just put a little script in your /sbin/rc3.d/
i called it S101ioscan_startup.sh -->
ioscan > /dev/null
vgchange -a y vgxx > /dev/null
and then link this file to /sbin/init.d
then try a reboot and look if the discs are available.
it tryed it often and it works all the time
sorry for my bad english i hope you are able to understand everything.
have a nice day..
msd
Thx for your reply, but my problem is that if the disk system is powered on when I power on the server or reboots the server then no disks is found at the disk system. Not even after an ioscan. But if I power off/on the disk system while the server is on and performs an Ioscan after then all disks are found.
It's very strange but could it be some cofiguration files that are faulty?

LEARN ABOUT ULTRIX
reboot
reboot(2) System Calls Manual reboot(2)
Name
reboot - reboot system or halt processor
Syntax
#include <sys/reboot.h>
reboot(howto)
int howto;
Arguments
howto The howto argument is a mask of options passed to the bootstrap program.
The bits of howto are:
RB_HALT
the processor is simply halted; no reboot takes place. RB_HALT should be used with caution.
RB_ASKNAME
Interpreted by the bootstrap program itself, causing it to inquire as to what file should be booted. Normally, the system
is booted from the file "xx(0,0)vmunix" without asking.
RB_SINGLE
Normally, the reboot procedure involves an automatic disk consistency check and then multi-user operations. RB_SINGLE pre-
vents the consistency check, rather simply booting the system with a single-user shell on the console. RB_SINGLE is inter-
preted by the init(8) program in the newly booted system. This switch is not available from the system call interface.
Only the superuser may a machine.
Description
The system call reboots the system, and is invoked automatically in the event of unrecoverable system failures. The system call interface
permits only RB_HALT or RB_AUTOBOOT to be passed to the reboot program; the other flags are used in scripts stored on the console storage
media or used in manual bootstrap procedures. When none of these options (for example, RB_AUTOBOOT) is given, the system is rebooted from
file in the root file system of unit 0 of a disk chosen in a processor-specific way. Normally, an automatic consistency check of the disks
is then performed.
Return Values
If successful, this call never returns. Otherwise, a -1 is returned, and an error is stored in the global variable errno.
Diagnostics
The call fails under the following condition:
[EPERM] The caller is not the superuser.
