Volume group "VolGroupSUN01" successfully created
This is correct?
When we umount the volume:
[root mezzicluslin02 ~]# umount /dev/VolGroupSUN00/LogVolSUN00
/home/SUNstorage
umount: /dev/mapper/VolGroupSUN00-LogVolSUN00: not mounted
umount: /dev/mapper/VolGroupSUN00-LogVolSUN00: not mounted

This is correct?
Kind regards,
