Hi Raghu,

There is a disk /dev/dsk/c3t5d0 which is configured in a vg and is not accessible. check the /etc/lvmtab file "strings /etc/lvmtab" and see which is the vg this disk belongs. This disk may be faulty and you may have to replace the disk. also do a ioscan on the system and check if you are able to see the disk as claimed. Do a diskinfo on the disk "diskinfo /dev/rdsk/c3t5d0" and do a pvdisplay "pvdisplay -v /dev/dsk/c3t5d0". Are you able to get all this info. If not, then either the disk is missing or it is faulty.

hope this helps.

Regds

On this server I only have one valum " vg00"
ioscan shows the disk is claimed,
#strings /etc/lvmtab
/dev/vg00
/dev/dsk/c2t6d0
/dev/dsk/c1t6d0
/dev/dsk/c3t5d0
#diskinfo /dev/rdsk/c3t5d0
SCSI describe of /dev/rdsk/c3t5d0
vendor: HP
product id: DVD-ROM 304
type: CD-ROM
Size: 458736 Kbytes
bytes per sector:2048
#pvdisplay -v /dev/dsk/c3t5d0
pvdisplay: Warning: couldn't query physical volume "/dev/dsk/c3t5d0":
The specified path does not correspond to physical volume attached to
this volume group
pvdisplay: Couldn't query the list of physical volumes.
pvdisplay: Couldn't retrieve the names of the physical volumes

pvdisplay: Cannot display physical volume "/dev/dsk/c3t5d0".
********************
when do a #pvdisplay -v /dev/dsk/c3t5d0- there is an error. is this means the disk may be bad?.

Looks like go got a DVD/CDROM into the vg.
May be a recent hardware upgrade was the culprit.

copy the /etc/lvmtab to /etc/lvmatb.old
#vgscan /dev/vg00
This will create a good lvmtab file.
