Description: Severity: Critical -- failure or failure imminent. A HSV110 controller has detected only one port of a Fibre Channel device. This Fibre Channel device has entered the Single Port on Fibre state which should be corrected as soon as possible. The identity of the Fibre Channel device is contained in the device field. The Fibre Channel port still able to communicate with the Fibre Channel device is contained in the cerpId field. The HSV110 controller internal Fibre Channel port number able to communicate with the Fibre Channel device is contained in the port field. The Fibre Channel port unable to communicate with the Fibre Channel device is contained in the missingCerpId field. The HSV110 controller internal Fibre Channel port number unable to communicate with the Fibre Channel device is contained in the missingPort field. The arbitrated loop physical address of the Fibre Channel device is contained in the alPa field. The location of the Fibre Channel device is determined by the content of the denclNum field as follows:

• If denclNum is less than 99, the location is as indicated by the content of the rackNum, denclNum, and bay fields.
• If denclNum is equal to 99, the location is unknown. Note that the content of the rackNum and bay fields is undefined in this case.
• If denclNum is greater than 99, the HSV110 controller does not have proof of the current location but the last known location is indicated by the content of the rackNum, denclNum, and bay fields. Subtract 100 from the content of those fields to determine the actual last known location. If there have been no configuration changes, the last known location values will be accurate. The identity contained in the device field should be used to confirm the last known location values.

Note that the content of the rackNum field will not be valid until a future release. Note also that in this case the content of the fedClass, and numTimes fields is undefined. The enclosures array shows the drive enclosures available on the Fibre Channel port identified in the cerpId field. The location of an available drive enclosure is determined by the content of the enclosures.denclNum field as follows:

• If enclosures.denclNum is less than 99, the location is as indicated by the content of the enclosures.rackNum and enclosures.denclNum fields.
• If enclosures.denclNum is equal to 99, the enclosures array entry is not used. Note that the content of the enclosures.rackNum field is undefined in this case.
• If enclosures.denclNum is greater than 99, the HSV110 controller does not have proof of the current location but the last known location is indicated by the content of the enclosures.rackNum and enclosures.denclNum fields. Subtract 100 from the content of those fields to determine the actual last known location. If there have been no configuration changes, the last known location values will be accurate.

Note that the content of the enclosures.rackNum field will not be valid until a future release.
