Event Reporting: Templates and Codes 5–89
0C Both controllers in a dual-redundant configuration are attempting to use the same SCSI ID (either 6 or 7
as indicated in the event report).
The other controller of the dual-redundant pair has been reset with the “Kill” line by the controller that
reported the event. Two possible problem sources are indicated:
■ A controller hardware failure.
■ A controller backplane failure.
First, follow repair action 20 for the “Killed” controller. If the problem persists follow repair action 20 for
the “Surviving” controller. If the problem still persists replace the controller backplane.
0D The Environmental Monitor Unit has detected an elevated temperature condition. Check the shelf and its
components for the cause of the fault.
0E The Environmental Monitor Unit has detected an external air-sense fault. Check components outside of
the shelf for the cause of the fault.
0F An environmental fault previously detected by the Environmental Monitor Unit is now fixed. This event
report is notification that the repair was successful.
10 Restore on-disk configuration information to original state.
11 The Uninterruptable Power Supply (UPS) signaled a two minute warning (TMW) before it signaled AC line
failure. UPS signals will be ignored until this condition clears.
■ Repair or replace the UPS.
■ The communication cable between the UPS and PVA is missing or damaged. Replace the cable.
20 Replace the controller module.
22 Replace the indicated cache module or the appropriate memory DIMMs on the indicated cache module.
23 Replace the indicated write cache battery. CAUTION: BATTERY REPLACEMENT MAY CAUSE INJURY.
24 Check for the following invalid write cache configurations:
■ If the wrong write cache module is installed, replace with the matching module or clear the invalid
cache error via the CLI. Refer to
HSG80 Array Controller ACS Version 8.5 CLI Reference Guide for
more information.
■ If the write cache module is missing, reseat cache if it is actually present, or add the missing cache
module, or clear the invalid cache error via the CLI. Refer to
HSG80 Array Controller ACS Version 8.5
CLI Reference Guide
for more details.
■ If in a dual-redundant configuration and one of the write cache modules is missing, match write
cache boards with both controllers.
25 An unrecoverable Memory System failure occurred. Upon restart the controller will generate one or more
Memory System Failure Event Sense Data Responses; follow the repair action(s) contained therein.
