Dont worry about "could not stat /dev/dsk/c0t0d0 " - this is most probably your DVD-ROM drive.

Did you replace c20t0d6 recently ? can you post the output of the following command ?

# diskinfo /dev/rdsk/c20t0d6

# echo "0x2008?4D" | adb /dev/dsk/c20t0d6

Thanks Sundar.
I didn't replace c20t0d6 recetnrly
# diskinfo /dev/rdsk/c20t0d6
SCSI describe of /dev/rdsk/c20t0d6:
vendor: COMPAQ
product id: HSV110 (C)COMPAQ
type: direct access
size: 524288000 Kbytes
bytes per sector: 512

# echo "0x2008?4D" | adb /dev/dsk/c20t0d6
2008: 0 0 0 0

I have used SAM to output some info as below:

vg06 LVM 16 of 409536 1 1

vg08 LVM 0 of 511920 1 1

view more infomation:
Disks - Status : Failed

The disk c20t0d6 doesnt seem to have any LVM header.

I think the forum will need some background on how you got here before anyone can give you some constructive feedback.

What prompted you to do the vgscan ?

P.S: though it is kind of you to assign points promptly, it may be misleading since you haven't got the solution to your problem as yet !!

Hi sundar

vgscan info i have listed at the top, "Physical Volume "/dev/dsk/c20t0d6" contains no LVM information" .
in /dev/vg08 dir on LV info
# ll /dev/vg08
total 0
crw-r----- 1 root sys 64 0x080000 Feb 26 12:01 group
doen't like other vg
# ll /dev/vg06
total 0
crw-r----- 1 root sys 64 0x060000 Mar 20 2005 group
br--r----- 1 root sys 64 0x060001 Mar 20 2005 lveva6
cr--r----- 1 root sys 64 0x060001 Mar 20 2005 rlveva6

#vgdisplay -v /dev/vg08 just list PV no LV info and PV Status is "unavailable". How to avilale it?

I didn't see any lv info in vg08, I think maybe the lv be del, as you know this server's admin was no longer in office, couldn't contact hime, so I try to lvcreate a new lv for vg08 and vg09 (vg09 couldn't access ...by vgscan info). but system respond:lvcreate: The logical volume "/dev/vg08/lvsys8" could not be created: No such device or address.

And Vg09, have /dev/vg09 dir but no any lv info in its dir, vgscan could not list it?

how to fix it, sorry too many erro and info.

I have used #vgcfgrestore to restore the config to the c20t0d6. the PV status become "available", I could re-create a lv for the vg but create lv have some problems, I have create a new thread named "logical volume problmes" list detail output and my questions, hope could get your experts's support.
thanks
