Logical Unit Masking
Logical Unit (LU) Masking gives the ability to assign access policies to a Logical Unit restricting
access to specific host servers through a controller port. This is opposed to “Open Access” where
the Logical Unit is accessible to all hosts connected to the port.
When the LU Masking feature is installed, access to specific hosts can be created through either
the Command Line Interface by specifying the host’s World Wide Port Name (WWPN) as the
optional “host ID” argument or through the web management interface’s Access Policy Wizard.
With LU Masking available, the wizard will show the WWPNs of connected hosts in its
“
Available
” policy tree (see Figure 35). The wizard also gives the ability to create host ID
aliases.
