Error while creating Volume Group

[Amod]

I am using HP-UX 11.11. When I am trying to create a VG using external disks it is giving me following error

# vgcreate /dev/vg01 /dev/dsk/c0t9d0
Increased the number of physical extents per physical volume to 17501.
vgcreate: Volume group "/dev/vg01" could not be created:
Inappropriate ioctl for device - the command was attempted on a
logical volume device rather than the control device.

Does anyone know the solution for this error ?

what does diskinfo -v /dev/rdsk/c0t9d0 says?

I assume you have done pvcreate

Hi,

#pvcreate -f /dev/rdsk/c0t9d0
#mkdir /dev/vg01
#cd /dev/vg01
#mknod group c 64 0x010000
#vgcreate vg01 /dev/dsk/c0t1d0

Hi,

#pvcreate -f /dev/rdsk/c0t9d0
#mkdir /dev/vg01
#cd /dev/vg01
#mknod group c 64 0x010000
#vgcreate vg01 /dev/dsk/c0t9d0

Have you created the /dev/vg01/group file with proper major and minor numbers.
The major number should be 64

Looks like the minor number for the volume group created is not correct.
you are using a number which is for a volume.
Use like

0x010000 for vg00
0x020000 for vg02,etc


Change it and it should work fine
Also make sure that they are unique taking into account of all the volume groups



Thanks

Thanks everybody

The problem was with 'group' file minor number. I corrected it and now I am able to create the VG.

Thanks,
Amod.
