330 HSG80 Users Guide
Figure 312 LUN Presentation Using Unit Offset on a Per-Host
Basis
Assigning Access Paths
The HSG80 subsystem allows the user to specify unit access privileges
to limit host access. This feature is defined on a unit-by-unit basis.
You can enable host access to a unit by mapping the unit accessible
through the specified host paths. (A path is the logical connection
between the host and the controller.) The path is referenced by the
name attached to the logical connection. Once the unit is set for access
through a path, the access privilege is defined.
Paths may be automatically added to the system through the host fibre
channel login process or manually with the ADD command. See
Appendix B, CLI Commands, for more information about this
procedure.
Note Even when hosts are automatically entered, user intervention is
still recommended to set a meaningful connection name.
