i am getting the following error can anybosy tell what could be the cause

# vgcreate /dev/vgboot /dev/dsk/c3t2d0
vgcreate: Cannot open the control file "/dev/vgboot/group":
No such device

[Torsten. · Accepted solution]

you need to create the "group" file first.

e.g.

mknod /dev/vgnew/group c 64 0x0z0000

where z is the number of your vg

Why you are creating a "vgboot"?

Before you create a VG you have to create the group file with mknod with the directory as the vgname.
So in your case
mkdir /dev/vgboot
mknod /dev/vgboot/group c 64 0x??0000
where ?? is the free number from your available vg which you can find by doing ll /dev/vg*/group
the run the vgcreate command

If you have more then one unix server, I would make sure to try and pick a group number that isn't used on on of your systems.

# ll /dev/vg* | grep group | sort -n
