Security Functions

ETERNUS2000 possesses functions that allow numbers of volumes, that can be recognized by a server, to
be expanded or restricted by adjusting how the logical units (LUN) seen by the host correspond to the vol-
umes within the storage system.
"LUN mapping function" and "Host Affinity function" are available as security functions.
• LUN Mapping function
LUN mapping is used to set the relationship between the logical units (LUN) of the host and the vol-
umes of the device, on a per device port basis.
Figure 1.17 LUN Mapping function
By specifying different LUN mapping per port, it is possible to set the volumes that can be accessed for
each server.
