Description: Severity: Critical -- failure or failure imminent. A drive enclosure transceiver error has been detected. The handle field contains the WWN of the drive enclosure containing the Drive Enclosure Environmental Monitoring Unit. This problem was detected by the Drive Enclosure Environmental Monitoring Unit located in the drive enclosure 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 and denclNum fields.
• If denclNum is equal to 99, the location is unknown. Note that the content of the rackNum field 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 and 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 rackNum field will not be valid until a future release. The location of the transceiver (1 through 4) is identified in the alarmErrorCode.field.en field as follows:

• 1 = Transceiver 01
• 2 = Transceiver 02
• 3 = Transceiver 03
• 4 = Transceiver 04

The transceiver error condition is described by the content of the alarmErrorCode.field.ec field as follows:

• 1 = The transceivers on this link are not the same type or they are incompatible with the drive enclosure I/O module. This error prevents the controller from establishing a link with the enclosure drives and eliminates the enclosure dual-loop capability.
• 2 = The transceiver can no longer detect a data signal. This error prevents the controller from transferring data on a loop and eliminates the enclosure dual-loop capability.
• 3 = The system has detected an FC-AL bus fault involving a transceiver. This error prevents the controller from transferring data on a loop and eliminates the enclosure dual-loop capability.
• 4 = The transceiver that was previously in this location has been removed.
• 5 = The transceiver in the specified location has detected invalid Fibre Channel characters.

The enclosures array shows the drive enclosures available on the Fibre Channel loop pair (0 = Loop A, 1 = Loop B) identified in the loop 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.
