Selected system administrator activities Partitioning on the basis of volume groups
4.1.3.4 Adding physical volumes to a physical volume group
Only physical volumes contained in the physical library may be specified.
● The form and detailed information are provided in the section “Physical Volume Opera-
tions » Add Physical Volumes” on page 223 .
The following information must be specified:
–
the VSN of the first physical volume
– an entry specifying whether the header of the added volume should be uncondi-
tionally overwritten with a CentricStor header
– the physical volume group (see section “Adding a physical volume group” on
page 66 )
– the number of physical volumes
– the type of physical volumes
The physical volumes are then incorporated in the CentricStor pool.
4.1.3.5 Assigning an LVG to a PVG
● The form and detailed information are provided in the section “Physical Volume Opera-
tions » Link/Unlink Volume Groups” on page 221 .
The following elements must be selected:
–
the logical volume group
– the physical volume group (original)
– a second physical volume group (copy, only applies for “Dual Save”)
The logical volume group is then assigned to the selected physical volume group(s).
4.1.3.6 Removing an assignment between an LVG and a PVG
Before executing this function, all logical volumes must be removed from the logical
group.
● The form and detailed information are provided in the section “Physical Volume Opera-
tions » Link/Unlink Volume Groups” on page 221 .
The following elements must be selected:
–
the logical volume group
– the physical volume group
The original physical volume group must be set to ’-unlinked-’. If a Dual-Save LVG
exists, the physical Dual-Save PVG must also be set to '-unlinked-'.
The assignment between the logical and physical volume groups is then removed.
