How to prevent loss of connectivity when using the 4XC7A14397 adapter

You can prevent loss of connectivity during a port failure by configuring your system with redundant paths to separate 4XC7A14397 HBAs.

The 4XC7A14397 HBA is a 4-port, 16 Gb FC adapter consisting of two 2-port pairs. The 4XC7A14397 adapter can be configured as target mode or initiator mode. Each 2-port pair is supported by a single ASIC (for example, Port 1 and Port 2 on ASIC 1 and Port 3 and Port 4 on ASIC 2). Both ports on a single ASIC must be configured to operate in the same mode, either target mode or initiator mode. If an error occurs with the ASIC supporting a pair, both ports in the pair go offline.

To prevent this loss of connectivity, you configure your system with redundant paths to separate 4XC7A14397 HBAs, or with redundant paths to ports supported by different ASICs on the HBA.
