Troubleshooting Troubleshooting This section provides instructions on resolving common problems that may occur while replacing controllers or cache modules.
Troubleshooting Table 3: Resolving an Invalid Cache - Serial Number Mismatch Error Message Description/Instruction Message INVALID CACHE - Cache should be installed in controller serial number xyz %CER-HSG> This controller ( replacement ) has an invalid cache module %CER-HSG> cache modules inconsistent with mirror mode Resolution 1.
Troubleshooting After a SHOW THIS_CONTROLLER or SHOW OTHER_CONTROLLER command is submitted, the controller displays one or both of the following cache conditions: Cache: Cache is GOOD Mirrored Cache: Cache is FAILED Note: This condition cannot be resolved with the CLEAR OTHER_CONTROLLER INVALID_CACHE DESTROY_UNFLUSHED_DATA command. To resolve the error message, see Table 4 on page 54.
Troubleshooting Table 4: Resolving a Failed Cache Error Message (Event 1) Details Message %CER-Atop> This controller (replacement) has an invalid cache module Resolution Caution: If the cache has failed, disable mirrored cache to clear the failed condition. Since unmirroring a controller pair destroys all persistent reservation bits in the controllers, you must halt all host activity to this controller pair before proceeding.
Troubleshooting Table 4: Resolving a Failed Cache Error Message (Event 1) (Continued) Details Resolution (Cont’d) Caution: In step 8, you must break up mirrored cache. Before completing this step, note that breaking up mirrored cache configurations loses persistent reservation conditions on the units in these controllers. Before proceeding with this procedure, inform customers and your manager that you are about to break the mirror cache configuration. 8.
Troubleshooting Table 5: Resolving a Failed Cache Error Message (Event 2) Details Message Resolution %CER-Atop> This controller (replacement) has an invalid cache module Caution: If the cache has failed, you must disable mirrored cache in order to clear the failed condition. Because unmirroring a controller pair will destroy all persistent reservation bits in the controllers, you must halt all host activity to this controller pair before proceeding.
Troubleshooting Resolving Unexpected Bugcheck Condition Error Messages If the replacement controller restarts at the same time that Enter or Return is pressed to terminate FRUTIL on the operational controller, an unexpected bugcheck condition error message can occur. Note: This condition cannot be cleared with CLI commands.
Troubleshooting Table 6: Resolving an Unexpected Bugcheck Condition Error Message (Continued) Resolution Resolution (Cont’d) 6. Set the hardware version and manufacturing level by entering the following command: DANGEROUS X HARDWARE=xyz Note: The xyz in the above command represents the hardware version that is located on the label on the bottom (component side) of the controller board. 7.
Software Anomalies Software Anomalies This section describes software anomalies inherent in ACS V8.7, 8.7-1, and V8.7-2. LED Code 38 When installing a controller, FRUTIL output incorrectly states that the controller halts with LED code 38. The controller actually halts with LED code 33. Installing Both the Controller and Cache Module FRUTIL allows you the option to install both controller and cache module. However, HP recommends that you do not install both the controller and cache module together.
