Chapter 8 Virtual Host Bus Adapters (vHBAs) 169
LUN Masking
Logical Unit Number (LUN) masking is an authorization feature that makes LUNs
available to some vHBAs but not to others. When you apply a LUN mask to a
vHBA, only that one vHBA on the host can detect the LUNs.
The standard location to configure LUN masking is on the disk array itself. In
OVN’s implementation, the Oracle Fabric Interconnect configures LUN masking in a
centralized SAN location—the vHBA (not the disk array):
