vgscan error

[Michael Steele_2]

OK, I don't see c2t0d0 in your ioscan. Here's what you pasted in:


# ioscan -funC disk

/dev/dsk/c3t2d0 /dev/rdsk/c3t2d0



So this looks like a typo or no one ever ran lvlnboot -r, -s, -b, or -d. So please paste in your make boot procedure as well as this pvdisplay:

pvdisplay -v /dev/dsk/c2t0d0

Why doesn't this show up in ioscan? Is this part of an array?

[James R. Ferguson]

Hi (again):

Well, this is strange. The Technical Knowledge Base has one reference that I can find; document #KBRC00011792.

The description of the problem seems to match yours.

Regards!

[Michael Steele_2]

Wow Jim, KBRC00011792. That's a good one.

The problem is very similar, but the solution is most unclear. What is an ENF patch, who is computer associates and what is the TNG product??

And, I am not dealing with any volume groups other than vg00.



quote----------------

This problem was solved by installing an ENF patch from Computer Associates for
the TNG product. After the patch is installed, relink libc.2 and reboot.

For further information see CA Issue # 12138274 about broken link for libc.2.

You wrote

vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c2t0d0":


The device file "/dev/dsk/c2t0d0" is in your configuration - this is wrong. It has to be "/dev/dsk/c2t0d0s2", since this is Itanium.

Please post

# lvlnboot -v

# strings /etc/lvmtab

Post error messages also, if you get any.

Michael Steele,

It shows up in ioscan:

In what configuration? Do you mean in /etc/lvmtab?
I realize Itanium deals with the "*s2" disks,
but I never did anything with /dev/dsk/c2t0d0. I was careful to work with /dev/dsk/c2t0d0s2.
That is surely the crux of the matter.



# lvlnboot -v
lvlnboot: Couldn't query physical volume "/dev/dsk/c2t0d0":
The specified path does not correspond to physical volume attached to
this volume group

# strings /etc/lvmtab

[Torsten.]

# strings /etc/lvmtab
/dev/vg00
/dev/dsk/c2t1d0s2
/dev/dsk/c2t0d0

^^^^^^^^^^^^^^^

Here it is!

and this is wrong!

Do a vgreduce!

[dictum9]

# vgreduce /dev/vg00 /dev/dsk/c2t0d0
vgreduce: Couldn't query physical volume "/dev/dsk/c2t0d0":
The specified path does not correspond to physical volume attached to
this volume group

[Torsten.]

# vgreduce -f vg00

should work.

If vg00 is OK now, we will check the other config.

[dictum9]

Torsten-,

Wow, it worked! No more errors in either vgscan or vgdisplay.

Repair done, please do the following steps.....:
1. save /etc/lvmtab to another file
2. remove /etc/lvmtab
3. use vgscan(1m) -v to re-create /etc/lvmtab
4. NOW use vgcfgbackup(1m) to save the LVM setup




# strings /etc/lvmtab

[Torsten.]

This is what I expected.

You used on one command the wrong device file without s2, this happened to me too.

Now you should check the LVM config on this disk and later start over with the mirroring process. Do not import the disk.

Finally post

# lvlnboot -v

# vgdisplay -v vg00

if you are in doubt.

[Torsten.]

Don't forget to do these steps first:

Hi Torsten!

Very well done! "...the problem is sometimes inside the system, sometimes in front of ..." :-))

/* NO POINTS PLEASE */

Regards!

...JRF...

[Torsten.]

Thank you James.

The question is, how often the problem is touching the keyboard... ;-)

Last week I missed one time the "s2" too while mirroring, the result was strange, but things like this are easy to remember.

[dictum9]

# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:

Swap: lvol2 on: /dev/dsk/c2t1d0s2
Dump: lvol2 on: /dev/dsk/c2t1d0s2, 0

[Torsten.]

Well done etc.

Now follow this procedure to mirror to a second disk:
