vgcreate issue (hlp plz)

[meekrob]

Hi All,

i am trying to create a new volume group "vgtest" via SAM on HP-UX 11iv1.

However, vgtest failed to create with the following message:

vgcreate: Minor number of /dev/vgtest/group is not unique.

/dev/vg01/group has the same minor number.  ((see attachment))

In addition, do also note the output of the below commands:

#kmtune | grep maxvgs    --->  it outputs "10"

#ls -l /dev/*/group

crw-r-----      1      root    sys    64    0x000000   ...........   /dev/vg00/group

#strings /etc/lvmtab

/dev/vg00

/dev/dsk/c2t2d0

VG00 is the only Volume Group present on that system.

Any suggestion would be much appreciated.

looks like you missed a couple of preliminary steps:

•mkdir /dev/<vgname>
•mknod /dev/<vgname>/group c 64 minor#

Hello Donna,
but as i mentioned that i was tryin to vgcreate using SAM. Isn't supposed that SAM will do that automatically?

[donna hofmeister]

one would think.  however when things "gang aft agley an' lea'e us nought but grief an' pain" it's time to do it by hand,

vgcreate: Minor number of /dev/vgtest/group is not unique.

/dev/vg01/group has the same minor number.




You probably have a previous vg01 in the lvm config backup files - please check.

Hello Torsten,
how could i check it?
vg00 is the only volume group available on that machine.
Even i tried to create (from SAM) other volume groups with different names (for testing) however, im gettin the same result.

[Torsten.]

What is in /etc/lvmconf ?

[meekrob]

#more /etc/lvmconf outputs the following:

vg00.conf
vg00.conf.old
vg01.conf
vg01.conf.old

[Torsten. · Accepted solution]

Move away

vg01.conf
vg01.conf.old

and try again - it should work now.

[meekrob]

after removing both files, i am still getting same result and vgcreate is still failing

@ Donna, i could go with this option by creating the volume group via command line interface, however, i need to create that volume group on an already configured LUN accessible by FC60 and im not too familiar with FC60 thats why im creating it via SAM. How could i know which physical disks (and their relative paths) map to that LUN?

Any help is much appreciated.
