Chapter 4. Implementing the SAN Data Gateway 305
Setting host access to LUNs
To view and set host access to particular LUNs, access the Virtual Private SAN
Access Settings by selecting Controls -> Access Options -> Virtual Private
SAN. This window will show all the hosts that have registered to the Gateway.
To allow a host to access a particular LUN, place a check mark in the row that
corresponds to the host. To disable access, the square must be clear, without a
check mark. The check mark is toggled on and off by clicking in each square.
Figure 4-38 provides an example of LUN masking.
Figure 4-38 Setting LUN masking
The host plymouth has access to LUNs 17 to 24 but does not have access to
LUNs 25 to 30. Conversely, the host at the top has access to LUNs 25 to 30, but
does not have access to LUNs 17 to 24. Using the scroll bar on the bottom, we
can scroll through all 255 available LUNs in the SAN Data Gateway, and enable
or disable access by adding or clearing the check mark. The scroll bar on the
right-hand side allows us to scroll through the different hosts. In this example,
there are only two hosts, but there can be several more.
