Installation 43

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 –s and –e physical extent (PE)

parameters of the vgcreate command. See

“LUSE device parameters”

(page 68).

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.

9. Use vgdisplay –v to verify that the volume group was created correctly.

The –v option displays the detailed volume group information.
