316 Implementing an Open IBM SAN
A check mark in the box allows a host access to a LUN, or clear the box if you
want to restrict access as described in , “Setting up a Virtual Private SAN” on
page 303. Figure 4-50 shows the host plymouth with access to assigned LUNS
17 to 24, and the NT host FIBRE1 is now set with access to LUNs 25 to 30.

Once you select Apply Changes and then Close, the new settings will be in
effect. For Windows NT to recognize the new devices, it will have to be restarted,
so that it will do a rescan.
The SWITCH entry in the VPS database does not require any check marks to be
set. Because the WWN of the host is known, and the switch WWPN is known,
LUN access is accomplished through the switch as if it was transparent.
Note: LUN access is not only affected by the VPS and Zoning with the SAN
Data Gateway, there is also Zoning within the IBM SAN Fibre Channel Switch.
Be aware of the zone settings within the IBM SAN Fibre Channel Switch
