Planning Considerations for Fibre Channel Topologies

—

When using inband director or switch management, either (or

both) of the FMS or OSMS features can be enabled. When

either (or both) features are enabled, the director or switch can

be set to open systems or FICON management style.

Upgrade fabric elements to a common feature set -

Ensure a

common set of PFE-keyed optional features (refer to

Optional

Feature Keys

) is installed on each fabric element. This reduces

errors due to director or switch incompatibility. In addition, the

SANtegrity Binding feature (with

Enterprise Fabric Mode

enabled)

is required to support FICON cascading.

Logically assign ports -

To organize devices into manageable

groups for zoning, director or switch ports should be logically

assigned to FCP port groups and FICON port groups. Although

FICON devices can be zoned by device WWN, they must also be

assigned logical port addresses that correspond to the port

addresses configured by the attached host HCD. FICON devices

must be attached to these assigned ports. In addition, PDCM

arrays affect port connections at the hardware level, so a range of

port addresses must be established for FCP device use, and a

separate range of port addresses must be established for FICON

device use. FCP ports should always be configured to allow

communication with each other but disallow communication

with FICON ports, and vice versa.

Configure FICON cascading -

Configure and enable FICON

cascading for all fabric elements. Refer to

FICON Cascading Best

Practices

for instructions. As part of this step, ensure the

SANtegrity Binding feature key is installed and

Enterprise Fabric

Mode

enabled for all directors and switches.

—

In conjunction with the SANtegrity Binding feature (fabric

and switch binding), consider enabling port binding from a

director or switch’s Element Manager application. Port

binding explicitly defines (by WWN or nickname) the device

allowed to attach to a Fibre Channel port and provides

additional security when logically allocating ports to FCP and

FICON groups. Although this process creates additional

configuration overhead, port binding is useful for

implementations that require protection from accidental

misconfigurations.
