Severity: Critical -- failure or failure imminent. A drive enclosure blower is not operating properly. This could affect the drive enclosure air flow and cause an over temperature condition. 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 dencl_num field as follows: <UL><LI>If dencl_num is less than 99, the location is as indicated by the content of the rack_num and dencl_num fields. <LI>If dencl_num is equal to 99, the location is unknown. Note that the content of the rack_num field is undefined in this case. <LI>If dencl_num 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 rack_num and dencl_num 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. </UL>Note that the content of the rack_num field will not be valid until a future release. The location of the affected blower (1 or 2) is identified in the alarm_error_code.field.en field. The cause of the improper operation is described by the content of the alarm_error_code.field.ec field as follows: <UL><LI>1 = The blower is operating at a speed that is outside of the Drive Enclosure Environmental Monitoring Unit specified range, possibly because of a bearing problem. <LI>2 = The blower is operating at a speed that is significantly outside of the Drive Enclosure Environmental Monitoring Unit specified range, possibly because of a bearing problem. <LI>3 = The blower has stopped. NOTE: The other blower (if operational) now operates at high speed and is a single point of failure. A single blower operating at high speed can provide sufficient air flow to cool an enclosure and the elements for up to 100 hours. However, operating an enclosure at temperatures approaching an overheating threshold can damage elements and may reduce the MTBF of a specific element. Hewlett-Packard therefore recommends immediate replacement of the defective blower. <LI>4 = The power supply reported an internal blower error. </UL><P> 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.dencl_num field as follows: <UL><LI>If enclosures.dencl_num is less than 99, the location is as indicated by the content of the enclosures.rack_num and enclosures.dencl_num fields. <LI>If enclosures.dencl_num is equal to 99, the enclosures array entry is not used. Note that the content of the enclosures.rack_num field is undefined in this case. <LI>If enclosures.dencl_num 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.rack_num and enclosures.dencl_num 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. </UL>Note that the content of the enclosures.rack_num field will not be valid until a future release.
