Creating Logical Volumes - HP XP7 Configuration Manual

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.
9. Use vgdisplay
displays the detailed volume group information.

# vgdisplay
