l The optical fiber is improperly connected or the optical fiber is faulty.
l The rate of the FC HBA card on the AS is inconsistent with that of the FC host port in the
storage system.
Fault Diagnosis
You can determine the cause for the fault through the following procedure:
l Cause 1: The optical fiber is improperly connected or the optical fiber is faulty.
1. Log in to the ISM to query whether the corresponding host port is normally connected,
or observe whether the link indicator of the corresponding FC host port in the storage
system is normal.
2. If the corresponding FC host port is not connected on the ISM or the link indicator is
off, you can determine that the optical fiber is improperly connected or the optical
fiber is faulty.
l Cause 2: The rate of the FC HBA card on the AS is inconsistent with that of the FC host
port in the storage system.
1. Query the rate of the FC HBA card on the AS.
2. In the navigation tree, choose the storage device whose FC host port is to be viewed.
3. On the menu bar, choose Configuration > FC Host Port Management... to go to
the FC Host Port Management interface.
4. Query the rate of the FC host port in the storage system that connects to the AS.
5. If the rate of the FC HBA card is inconsistent with that of the FC host port, you can
determine that the rate of the FC HBA card is inconsistent with that of the FC host
port in the storage system.
Procedure
l Cause 1: The optical fiber is improperly connected or the optical fiber is faulty.
1. Insert and remove the optical fiber again or replace the optical fiber by a new one.
2. The link indicator of the FC host port is on. Available links are displayed on the ISM
and the storage services are normal.
l Cause 2: The rate of the FC HBA card on the AS is inconsistent with that of the FC host
port in the storage system.
1. Adjust the rate of the FC HBA card to be consistent with that of the FC host port.
2. Available links are displayed on the ISM and the storage services are normal.
