Can't access external disk after reboot
Hi,
I have an HP RX4640 running HP-UX 11iv3 with two internal disks and its connected to a HP disk system 2400 with fibre cable.
If the storage system is online before the server is on then the server can't find the disks. And I get the following error messages:
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c4t0d0"
cgchange: Couldn't activate volume group "/dev/vg01", Quorum not present, or some physical volume(s) are missing.
vgchange: Couldn't query physical volume "/dev/dsk/c4t0d0"
vgchange: Couldn't query physical volume "/dev/dsk/c4t1d0"
vgchange: Couldn't query physical volume "/dev/dsk/c4t2d0" etc...
The volume group is not activated
The path of the physical volume refers to a device that does not exist, or is not configured in the kernel.
If I power off/on the DS2400 when the server is online and performs an ioscan -fnC disk, then it finds the disks and I am able to activate the volume group.
When I look in /etc/fstab the mounting point is missing but it didn't help to add this.
Really could use some help before I begin to reinstall HP-UX
Thx in advance

LEARN ABOUT ULTRIX
reboot
reboot(8) System Manager's Manual reboot(8)
Name
reboot - automatic reboot procedures
Syntax
/etc/reboot [ -n ] [ -q ]
Description
The ULTRIX system is booted by loading a kernel image, usually into memory at location zero and transferring to zero. Because the system
is not reenterable, the kernel image must be read in from disk each time the system is bootstrapped.
When the reboot of a running system is desired, is normally used. If there are no users, can be used. The command causes the disks to be
synced, and then a multiuser reboot is initiated. The system is booted and an automatic disk check is performed. If the procedure suc-
ceeds, the system is then brought up for the users.
The system will reboot itself after a power failure or after a crash, provided auto-restart is enabled on your system. A consistency check
of the file systems will be performed and, unless the check fails, the system will resume multiuser operations.
Options
-n Prevents the disks from being synced.
-q Reboots quickly and ungracefully, without shutting down running processes first.
