Two additional pieces of information that I forget to mention. After the
SUSE 9 guest is re-IPLed, the volume group can most of the time be
activated by entering a "vgchange -ay" command. Occassionally this does
not work and we have issue a "config" command that will rebuild the
links and then the "vgchange"
Thanks, Bob

Subject: Re: fcp disk under SUSE9
We use FCP with SLES 9 all the time.
Is your disk on two paths? If so, then you also need to have MPIO
installed and running. (multipathd and boot.multipath)
You ran mkinitrd and zipl, but did you notice if they were successful?
Is /boot on its own disk? Is it mounted RW? Is the underlying minidisk
RW?
You said that you have to define the vol group manually. That's how we
always do it: pvcreate, vgcreate (or vgextend), and lvcreate (or
lvextend).
I recommend that you NOT partition a SAN volume intended to be used as a
PV. (ie: pvcreate /dev/sda instead of pvcreate /dev/sda1) But I don't
think that is your problem. More inclined to think there is a hardware
problem, but how then does SLES 10 cope?
I hope this helps.
