switches and EVA controllers. Whereas the dual HBA server has multi-path software that manages
the two HBAs and their connections to the switch (with the exception of OpenVMS and Tru64 UNIX

represents the fabric zone that must be established for the single path HBA server. Note that in
Figure 30 (page 114), servers with OpenVMS or Tru64 UNIX operating system should be zoned
with two controllers.
