another volume group.

greater than the maximum capacity allowed. See
B - Disk array device emulations.
Verify that the capacity of the volume group is not less than
the total capacity of the partitioned logical volume.
Verify that the character-type device file is entered correctly
with newfs (for example, /dev/vg01/r/vo/x).
Verify that the host was restarted correctly.
Verify that the file system attributes are correct.Verify that
the auto-mount information in the /etc/checklist (/etc/fstab)
file is correct.
Reboot the host.
