4.1.3.10 Removing physical volumes from a physical volume group
Only scratch tapes which do not contain any valid logical volumes can be removed,
unless the physical volumes have been reorganized prior to doing this (flag is set).
● The form and detailed information are provided in the section “Physical Volume Opera-
tions » Erase Physical Volumes” on page 226.
The following information must be specified:
– the VSN of the first physical volume
– the physical volume group
– the number of physical volumes
– flag for switching on/off a preceding reorganization
The physical volumes are then removed from the CentricStor pool. They are no longer
used and can be removed from the library.
4.1.3.11 Removing physical volume groups
Physical volume groups which have been made known to the system with the “Distribute
and Activate” function can be removed from the “Physical Volume Groups” form (see
page 181). However, this is possible only if the following prerequisites are satisfied:
– The physical volume group concerned may no longer be linked to a logical volume
group.
– The physical volume group may not contain any physical volumes.
The two physical volume groups BASE and TR-PVG cannot be removed.
1. Select the physical volume group to be removed in the list.
2. Click on the “To Be Deleted” button (see page 183) and select “YES”.
3. Click on the “OK” button.
