6.5 Replacing Fibre Channel HBAs in the Application
Processor
6.5.1
Overview
Depending on the number of shelves and the type of VTL configuration, the Application
Processor will be populated with up to five fibre channel HBAs. The following diagram shows
the FC HBA population for a two shelf system: two FC HBAs are used for host connections and
one FC HBA is used for a connections to the two shelves. Note that your fibre card
configuration may vary from the following diagram depending on the number of shelves
installed in the cabinet. Refer to DOC00482 for other FC HBA configurations.

6.5.2
Fibre Channel HBA Enumeration in the OS
When you populate the HBAs in the Application Processor, the operating system will discover
and enumerate the HBA ports with values from 100 to 109. The host connections will be the
highest enumeration values while the shelf connections will be the lowest enumeration values.
For example, if you have a
two-shelf
system with
three HBAs
with dual ports in the application
processor, the ports connected to the shelves will be enumerated as 100 and 101 and the ports
connected to the four hosts will be 102, 103, 104 and 105. If you have add another HBA for a
three-shelf system
(f
our HBAs
), the shelf port connections will be 100, 101, 102 and 103 while
the host connections will be 104, 105, 106 and 107.
