Description: Severity: Critical -- failure or failure imminent. A drive enclosure power supply is improperly installed or missing. This could affect the drive enclosure air flow and cause an over temperature condition. The operational power supply will automatically shut down after a short period of time, thereby disabling the drive enclosure. This condition remains active until either the problem is corrected, or the operational power supply shuts down, whichever occurs first. 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 affected power supply (1 or 2) is identified in the alarmErrorCode.field.en field. 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.
