Re: vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c4t0d7":
Can you also please give these O/Ps
#strings /etc/lvmtab
#ioscan -fnCdisk
#vgdisplay -v /dev/vgmost
#vgcfgresore -l -n /dev/vgmost
#dd if=/dev/dsk/c4t0d7 of=/dev/null count=10000
Reason is that the VG /dev/vgmost is having Cur PV as 6 and Act PV as 7.
/dev/dsk/c4t0d7 belong to this VG.
Sorry for the inconvenience,
but please give the Above O/pS.
Regards

Re: vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c4t0d7":
As avinash says that vgcfgrestore can be done to bring back that /dev/dsk/c4t7d0 into the VG /dev/vgmost is correct.
i made a typo in the Earlier post.
That is
#vgcfgrestore -l -n /dev/vgmost.
this shows(lists) the disks(PVs) that are a part of the VG /dev/vgmost as per the VG Config File /etc/lvmconf/vgmost.conf.
From the O/ps sent this seems.
1)the disk /dev/dsk/c4t0d7 has the alternate paths as /dev/dsk/c6t0d7 /dev/dsk/c8t0d7 /dev/dsk/c10t0d7.
2)fcmsutil and the status of the other VGs tell that the FC card is working fine.
3)this is a 60 GB LUN assigned from the storage.
4)diskinfo and dd show that you can read and write to the disk as OK.
5)ioscan shows that the disk is available and CLAIMED.
6)strings /etc/lvmtab shows that the disk was configured as a part of the VG /dev/vgmost.
Are not you facing any issues with the other LVs of the VG /dev/vgmost?
If you are not facing any problem with the LVs of this VG (One PV gone entirely 60 GB in size and you are not having problems with the LVs in the VG!!.. might be there had been Mirrors of the LVs?
1) please run a lvdisplay -v on all the LVs of the VG /dev/vgmost and give the O/pS) Can you please try and give the O/Ps
2) #vgcfgrestore -l -n /dev/vgmost
try this one and also give the O/Ps
3) #pvdisplay -v /dev/dsk/c4t0d7.
Also check once from the Storage team if they have
4) misassigned this LUN also to some Other system.
5)ask them to check the health and assisnment of this LUN from the storage side.
6)or might be this was temporarily assigned from the storage to this server.
yes, the solution as suggested by Avinash is
vgcfgrestore -n /dev/vgmost /dev/rdsk/c4t0d7
but think once please check the above said information also.
7) Please check the Event Logs also at /etc/opt/resmon/log/event.log for any incident regarding to this LUN.
Please answer the Queries as asked as 1,2,3,4
5,6 and 7
@Avinah::: Close to becoming a Wizard... Advance Congrats..
Regards
Sujit

ioscan".
First check /etc/lvmtab with strings command.
Check the lvmtab entries are the same with error pv names.
If not same,
do take backup of "/etc/lvmtab" and do "vgscan".
check new lvmtab entry with strings command and compare new lvmtab with the old lvmtab.
Now try with vgdisplay or ioscan.
