vgchange: Warning: couldn't query physical volume "/dev/dsk/c8t0d1":The specified path does not correspond to physical volume attached to this volume group
When physical discs are formatted for LVM they are given a unique identity. This error message is usually because the unix device path points to a physical disc which is not the one expected. You have this error for all the non-system discs.

Until you can see all 32 discs in ioscan with their correct device addresses there is nothing sensible you can do with unix LVM commands.
If you have two SANs, is one of them dead?

We are assuming throughout that this is a standalone system which was previously working and suddenly failed, and which has no shared disc paths to another server. (I think that vbe has this idea in post #6).

@ vbe, they are on EVA storage which does the Raid 5.
It's a single server, acting as a test server for the company, the try applications here before going live on the development servers.

@ methyl, the weird thing is that I only have 16 disks in the EVA, it's weird that it shows 32. All 16 disks of these VGs (vgdvqatr, vgr3dev0, vgr3qas0 and vgr3trn0) appear in the ioscan output and are the same mount points in the table and in the (old saved) bdf output.

There are 5 servers connected to this EVA, and they are functioning properly.

Below the output of cat /etc/fstab

Code:

And cat /etc/lvmrc output

Code:

# /etc/lvmrc
#
# This file is sourced by /sbin/lvmrc. This file contains the flags
# AUTO_VG_ACTIVATE and RESYNC which are required by the script in /sbin/lvmrc.
# These flags must be set to valid values (see below).
#

#
# The activation of Volume Groups may be customized by setting the
# AUTO_VG_ACTIVATE flag to 0 and customizing the function
# custom_vg_activation()
#

#
#       To disable automatic volume group activation,
#       set AUTO_VG_ACTIVATE to 0.
#

AUTO_VG_ACTIVATE=0

#
#       The variable RESYNC controls the order in which
#       Volume Groups are resyncronized. Allowed values
#       are:
#               "PARALLEL"      - resync all VGs at once.
#               "SERIAL"        - resync VGs one at a time.
#
#       SERIAL will take longer but will have less of an
#       impact on overall I/O performance.
#

#
#       Add customized volume group activation here.
#       A function is available that will synchronize all

#       This routine is only executed if AUTO_VG_ACTIVATE
#       equals 0.

Its not weird that it shows 32 if you have 2 controllers that can see the same disks using 2 separate paths... If this is your case then one controller is dead or faulty or the connections... ( could be on EVA side also... but here I am not much of help never had EVAs used only clarrion (once) and HDS systems...)


A mistake not to do in your case is to use vgscan ( you are doomed if you did...) for you have fancy vg and specially lvol names!!! and I suppose you have no vg map files...)

start by a simple ioscan then:
Code:
ant:/home/vbe $ ioscan -funC ctl

                           /dev/rscsi/c2t7d0
ctl       3  0/0/2/1.7.0    sctl   CLAIMED     DEVICE       Initiator

                           /dev/rscsi/c13t0d0

                           /dev/rscsi/c7t7d0
ctl       6  0/6/0/1.7.0    sctl   CLAIMED     DEVICE       Initiator
                           /dev/rscsi/c8t7d0
ctl       9  0/7/0/0.1.196.255.0.0.0  sctl   CLAIMED     DEVICE       HITACHI OPEN-V
                           /dev/rscsi/c15t0d0

so that we can see what controllers you have...

None of the controllers is down, I already checked on the EVA Command View.

Below is an output of ioscan -fnC disk of another server connected to this EVA, it shows 16 disks as well, and this server works perfectly.

Just noticed your in your lvmrc you are not using auto_activate_vg but have a custom: vg activation, do you know the reason? Have you seen the sequence order you are to respect ?
Code:
custom_vg_activation()
{
# e.g. /sbin/vgchange -a y -s
# parallel_vg_sync "/dev/vg00 /dev/vg01"
# parallel_vg_sync "/dev/vg02 /dev/vg03"
/sbin/vgchange -a y
parallel_vg_sync "/dev/vgr3dev0 "
parallel_vg_sync "/dev/vgr3qas0 "
parallel_vg_sync "/dev/vgr3trn0 "
parallel_vg_sync "/dev/vgr3trn1 "
parallel_vg_sync "/dev/vglunsap /dev/vgdvqatr"
return 0
}

What do you have in /etc/lvmconf?
Do you have any output with this:
ioscan -funC fc ?
