Re: vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c4t0d7":

hi


this means that /dev/dsk/c4t0d7 is not being sensed by the system.

do

#ioscan -fnCdisk
see if the disk /dev/dsk/c4t0d7 shows NO_HW

#diskinfo /dev/rdsk/c4t0d7
see if size shows 0 Kbytes.

see
using dd read the blocks from disk.

#dd if=/dev/rdsk/c4t0d7 of=/dev/null


see if that fails.


if the disk is failed which seems like that it has, you will need to replace that

Re: vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c4t0d7":

Since more than one disks failed, then if those failed disks are in SAN, it might be the connection of HBA to switch to SAN has problems. If they are internal disks then the system hardware has an issue.

It need more information to figure out the real reason for the failure.

Re: vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c4t0d7":

Hi


Tingli has made a valid point. These 4 disknames seems to be 4 paths of the same disk and the disk belongs to the VG /dev/vgmost which is showing Cur PV as 8 and act PV as 1 , that seems to be a part of /dev/vgmost.

Please use bdf and lvdisplay to see if all the LVs in the VG are mounted and intact.
from lvdisplay -v on all the LVs in the /dev/vgmost try to locate if the LVs had some extents on that PV /dev/dsk/c4t0d7.


Also might be that LUN has been deassigned from the Storage Side and is no more presented to the server.

This is so because this seems that all 4 paths are inactive, you can also check what is the status of the FC Interface , or this is a FC cable gone?

#ioscan -fnCfc
this shall show FC interfaces like /dev/fcd0 and /dev/fcd1
#fcmsutil /dev/fcd0
#fcmsutil /dev/fcd1

see that you can see Online and WWN N-port ID and Port ID.

Might be a broken cable also.

Will be good if you can post the O/Ps for

#ioscan -fnCdisk
#ioscan -fnCfc
#fcmsutil /dev/fcd0
#fcmsutil /dev/fcd1
#vgdisplay -v

Re: vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c4t0d7":

The disk is not getting sensed.

Cur PV 7
Act PV 6 <<==

Check the event.log for any error

/var/opt/resmon/log/event.log

Also provide the output of the following

# mv /etc/lvmtab /etc/lvmtab.working
# vgscan -pv
# mv /etc/lvmtab.working /etc/lvmtab

# ioscan -fnC disk
# strings /etc/lvmtab
