I wanted to import a VG, then this message appeared. What can I do ???
Would a "vgcfgrestore" help ???
Pls help me! I need fast help ?

Seems that there are no LVM info on that disk. Are you 100% sure it should be?
A vgcfgrestore will (only) restore the LVM header on the disk. If that's all that's missing you are OK. If there was no lvols on the disk you have a disk with a LVM hearder and nothig else. It there where som other data/fs on the disk you have probably lost it. You could try a fsck on it in case it was a hole disk HFS.
You may also have a faulty disk.

You need to restore the VGRA onto c16t5d4..

# vgcfgrestore -n /dev/vgXX /dev/rdsk/c16t5d4

Hi,

Seeing your are importing, are you sure that you have the right disk? If you are not sure you can use the preview method to find out.

# vgimport -v -p -m mymapfile /dev/myvg /dev/dsk/cxtydz

When disks are connected to another system most of the time they do not end up with same naming convention.

when I try "vgcfgrestore -n vgxxx /dev/rdsk/cYXtABdZZ", I get this error:
vgcfgrestore: Volume group "/dev/vgxxx" does not exist in the "/etc/lvmtab" file.
vgcfgrestore: IO error on Physical Volume device /dev/rdsk/cYXtABdZZ

so what else could solve the problem ?

There are 2 completely different scenarios here - be sure you are doing the correct one!!

The first is if this disk was mirrored and you then replaced it with a new blank disk - then you can use vgcfgrestore to incorporate it back into an existing volume group (the same one it was in before).

OR

If this disk came from another server or used to have volume group data on it, then you use vgimport to bring it into a volume group so you can mount its logical volumes. To do this you must create the volume group first before you try to import it;
mkdir /dev/vgXX
mknod /dev/vgXX/group c 64 0x0?0000
(where ? is a unique number - check other /dev/vg??/group files first)
then you can try vgimport on that disk. If it comes back and says no vg info on it then the disk is blank - you have the wrong disk.

Be sure you attempt the correct scenario or else you may end up wiping the disk!!

Please give us some more information. Where does this disk come from? Another system, exported on this or a spare disk. Why do you want to import it? (Not just creata a new VG and lvols.)
If you want to import it you have to have VG to import it to like Stefan suggests.

Yes I know.
I tried "vgimport -v -m vgxxx.map -f vgxxx.infile vgxxx "
But just this happened.

Beginning the import process on Volume Group "vgxxx".

I start to get confused ?!
I really don't know waht else I coukd try.

Was this disk previously attached to a different system? If so, are you sure that you have the correct disk device name?

Elif,

There is nothing else you can try. Your disk is blank. Sorry. Only possibility is if you have the wrong disk ?

Hi Elif,

Let me start it again ;-)

There are few doubts.
1. Do you really want to do a vgimport or you want to create a new Volume group? This question might sound stupid but still..

2. Is your server on which you want to import this disk a part of a cluster ?

3. Was it a part of some mirror disks set ?

4. And by the way did you try using 'sam' for importing ?

Because then all of us can then start giving solution according to the situation.

Hi Elif,

As the message says, there is no VG/LV info on this disk to import. Seems like an unused disk.

Hope this helps.

Hi Elif:

I agree with Stefan, you don't have any LVM information on the disk. One way to prove this is to look at the VGID (Volume Group ID). If the disk in question belongs or belonged to a volume group on *any* server you will have a non-zero VGID. Do this:

# echo 0x2010?2X|adb /dev/dsk/c16t5d4|awk '{print tolower($2 $3)}
