Setting up LUN security

The storage array administrator must configure the storage array so that other hosts cannot access the array LUNs intended for use by Data ONTAP.

About this task

The concept of LUN security is similar to zoning except that LUN security is set up on the storage array. LUN security keeps different servers from using each other's storage on the SAN. LUN security might also be referred to as LUN masking.


  1. Set up LUN security on the storage array.
  2. Create host groups, or the equivalent, for the Data ONTAP system.
    The term host group is used on some storage arrays to describe a configuration parameter that enables you to specify host access to specific ports on the storage array. Different storage arrays use different terms to describe this configuration parameter. Each storage array vendor has its own process for creating a host group or the equivalent.
