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..

volreattach
volreattach(8) System Manager's Manual volreattach(8) NAME
volreattach - Reattaches disk drives that have once again become accessible SYNOPSIS
/usr/sbin/volreattach [-rb] [accessname...] /usr/sbin/volreattach -c accessname OPTIONS
The volreattach utility has the following options: Calls the volrecover utility to attempt to recover stale plexes of any volumes on the failed disk. Performs the reattach operation in the background. Checks whether a reattach is possible. No operation is performed, but the name of the disk group and disk media name at which the disk can be reattached is displayed. DESCRIPTION
The volreattach utility attempts to reattach disks using the same disk group and media names they had before detachment. This operation may be necessary if a disk has a transient failure, or if some disk drivers are unloaded or unloadable when the Logical Storage Manager is started, causing disks to enter the failed state. If the problem is fixed, the volreattach command can be used to reattach the disks without plexes being flagged as stale, as long as the reattach happens before any volumes on the disk are started. The volreattach command is called from the voldiskadm menus as part of disk recovery. The volreattach utility tries to find a disk with a disk group and disk ID matching that of the disk(s) being reattached. If the matching disk is found, the reattach operation may still fail if the original cause (or some other cause) for the disk failure still exists. EXIT CODES
A zero exit status is returned if it is possible to perform a reattach. Otherwise, non-zero is returned. SEE ALSO
