Mark,

Did you install by any change cluster on this server, check a file in /dev/slvmvg file, this file will have a same major no like lvm, so this may cause a problem. So move that file and try running vgscan to solve this problem.

There are a number of causes, from changed VGID numbers on some of the disks to bogus lvols or other junk files in the volume group. You can usually fix this by rebuilding lvmtab:

mv /etc/lvmtab /etc/lvmtab.old
vgscan -v
vgchange -a y

That should clear up the corruption in lvmtab.

There did exist a vg "/dev/"
and it is same as vg00. I don't know what cause this, maybe someone do the wronge configuration.

/dev/vg00
/dev/dsk/c1t2d0
/dev/dsk/c2t2d0
/dev/
/dev/dsk/c1t2d0
/dev/dsk/c2t2d0

Mark,
I am confused ! Did you read the links I provided ?

The second link in my answer details:

mv /etc/lvmtab /etc/lvmtab.old
vgscan -a

Which you awarded 10 points to in a number of other answers, but my answer was worth
less than
"1-3: The answer didn't really help answer my question, but thanks for your assistance!"

I provide links in my answers, so people can see the various ways the problem may be resolved, giving you more than one solution.

Mark.

Pete,
thanks for the link! I agree that harassing posters for points is wrong, I was only wondering why my (problem resolving)answer at 12:02 was worthless, compared to same solution answers 20 minutes later.

I wondered whether my links had been read, which would have resolved the problem and closed the thread, saving people the effort to provide same solutions.

As I stated, I prefer to post the links, as normally more than one solution is proposed, which may be better suited to your individual fault.

Mark,
my sincerest apologies if you felt harrassed.
