Global Logical Volumes
Specific host mapping cannot be carried out for global logical volumes.
A global logical volume can be converted to a private logical volume.
This will remove the global volume from the ports, that it has been mapped to and
with that from all the hosts that are logged into those ports. The 'Modify/Delete
Volume' screen allows a user to convert a volume from private to global or vice-
versa.
NOTE: Global Volume Mapping overrides Private Volume Mapping!
Assume the following scenario:
Private volume LV1 mapped to host 1 at LUN 0 with port 1A enabled.
Global volume LV2 mapped to LUN 0 for port 1A.
Host 1 logged into port 1A.
In this scenario host 1 will not see private volume LV1 at LUN0 as the global
volume mapping has precedence.
The following table gives an explanation of the Private Logical Volumes Mapping table:
