FCoE and Fibre Channel problems

•
If fabric offline counts increase and fabric maintenance is not occurring, this may indicate a
serious fabric problem. Refer to your switch troubleshooting guide to isolate and resolve the
problem.
Virtual devices not listed in name server
If virtual devices are not listed in the fabric’s name server, refer to the following descriptions of
possible causes and recommended actions to help resolve the problem.
Possible Causes:
•
Problem in the fabric or a protocol issue between the adapter and fabric.
•
NPIV is not supported or is disabled on the switch.
Action: Check virtual port statistics, such as FDISC sent, FDISC accept, and No NPIV support
statistics. Refer to
on page 71 for methods to display virtual port statistics.
Adapter not registering with the name server or cannot access storage
If the adapter is not registering with the name server or cannot access storage, refer to the
following descriptions of possible causes and recommended actions to help solve the problem.
1. Possible Cause: Adapter cannot log in to the name server.
Action: Display logical port statistics (refer to
on page 68 for details on
displaying these statistics). Check for increasing name server port login (NS PLOGI) error
rejects and unknown name server port login response (NS login unknown rsp). These errors
mean that the adapter most likely cannot log in to the name server.
2. Possible Cause: Adapter has a problem registering with the name server.
Action: Display logical port statistics (refer to
on page 68 for details on
displaying these statistics). Check for increasing errors of the following types. These indicate
that the adapter has a problem registering with the name server:
•
Name server register symbolic port name identifier (NS RSPN_ID) errors.
•
Name server register symbolic port name identifier response (NS RFT_ID rsp) errors.
•
Name server register symbolic port name identifier response rejects (NS RFT_ID rejects).
3. Possible Cause: Adapter has a problem querying the name server for available storage.
Action: Display logical port statistics (refer to
on page 68 for details on
displaying these statistics). Check for increasing name server get all port ID response (NS
GID_FT rsp), rejects (NS_GID FT rejects), or unknown responses (NS_GID FT unknown rsp).
This indicates that the adapter has a problem querying the name server for available storage.
FCoE link is down (CNAs only)
The FCoE link is down between the CNA and switch.
1. Possible Cause: The FCoE link is not administratively enabled.
Action: Determine if the link is enabled by entering the BCU port --list command. If the port is
administratively disabled, the “port state” field will show Disabled.
Action: Enable the port by entering the BCU port --enable <port_id> command.
