5. Choose a unique minor number for the new group file in sequential order (for example, when
existing volume groups are vg00-vg05 and the next group name is vg06, use minor number 06
for the vg06 group file).
The minor numbers are hexadecimal (for example, the 10th minor number is 0x0a0000).
6. Use mknod to create the group file for the new directory. Specify the volume group name, major
number, and minor number. The major number for all group files is 64.
Example
In this example: group name = vg06, major number of group file = 64, minor number of existing
group file = 06 (which must be unique for each volume group), and c = character.
# mknod /dev/vg06/group c 64 0x060000
:
7. Create the volume group.
To allocate more than one physical volume to the new volume group, add the other physical
volumes, separated by a space.
Example
# vgcreate /dev/vg06 /dev/dsk/c6t0d0
Volume group "/dev/vg06" has been successfully created.
Volume group configuration for /dev/vg06 has been saved in
/etc/1vmconf/vg06.conf.
For Logical Unit Size Expansion (LUSE) volumes that contain more than 17 OPEN-8/9 LDEVs or
more than 7043 MB (OPEN-8/9*n-CVS), use the
of the vgcreate command. See
If you need to delete a volume group, use the vgremove command (for example, vgremove
/dev/vgnn). If the vgremove command does not work because the volume group is not active,
use the vgexport command (for example, vgexport /dev/vgnn).
8. Use the vgdisplay command to verify that the new directory was created.
