Adapter driver installation verification

Problems with adapter operation may be due to improper hardware or software installation,
incompatibility between the adapter and your host system, unsupported SFPs installed on the
adapter, improper cable connected to the fabric, or the adapter not operating within specifications.
Determine if problems may exist because of these factors by reviewing your installation with
information in the Brocade Adapters Installation and Reference Manual listed in

Cables that are not rated or compatible with adapter port speeds. Refer to cable specifications
in the Brocade Adapters Installation and Reference Manual.
Faulty switch or adapter SFPs. Verify if an SFP is the problem by connecting a different link to
the adapter port or, if convenient, replace the cable with a cable of known quality. If the errors
or invalid data on the link still indicate a cable problem, the SFP may be faulty. Try replacing the
SFP.
SFP issues on the adapter or switch. For example, the SFP may not be compatible with the
adapter, but is compatible with the switch, or vice versa. SCSI retries and time-outs determine
communication between the adapter and storage. Dropped packets cause time-outs, and
packets can drop because of SFP issues. Run the BCU port -stats command to display port
statistics, and look for errors and dropped frames.
