Actions linked with “OK”
1. Before the PVG is linked, the logical volume size is checked: If the LV size is > 2 GB,
the capacity of the PVs already assigned must be twice as large as the LV size,
otherwise the assignment is rejected with the following message:
Attempting to link PVGs (<PVG1>,>PVG2>) to LVG (<LVG>): The capacity of
the PVs of PVG <PVG1> is too small
2. The actions entered at the graphical interface are resolved in one or more commands
to the PLM. A change in assignment leads to an “Unlink” followed by a “Link” with the
new PVG name.
The responses of the PLM, including any error messages, are displayed in an info box.
This box lists the results of all PLM commands that were initiated with “OK”.
Please note:
– After pressing “OK”, wait for the info box with the acknowledgments. The
action is not actually concluded until this box appears.
– Before logical volumes are linked again following an LVG Unlink, the LVG
must be linked to a (different) PVG.
If the LVG-PVG assignment is to be changed in exceptional cases, you can proceed as
follows:
1. Use the VLM command “Change Volume Group” to change the LVG association of
all logical volumes of the LVG.
2. Assign the now emptied LVG to a different PVG.
3. Reestablish the original assignment by issuing further “Change Volume Group”
commands.
