Can't access external disk after reboot

hoff · #1 (**permalink**) 09-11-2008

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
/Hoff
