Cache Has Been Disabled; Likely Caused By a Loose Pin on One of the RAM Chips

Description: Cache has been disabled due to a large number of ECC errors detected while testing the cache during POST. This is probably caused by a loose pin on one of the RAM chips.

Action: Try reseating the cache to the controller. If that does not work, replace the cache.

Configuration Signature is Zero

Description: ADU ("Array Diagnostic Utility" on page 63) detected that NVRAM contains a configuration signature of zero. Old versions of the server setup utility could cause this.

Action: Run the latest version of server setup utility to configure the controller and NVRAM.

Configuration Signature Mismatch

Description: The array accelerator board is configured for a different array controller board. The configuration signature on the array accelerator board does not match the one stored on the array controller board.

Action: To recognize the array accelerator board, run ACU ("Array Configuration Utility" on page 54).

Controller Communication Failure Occurred

Description: Controller communication failure occurred. ADU was unable to successfully issue commands to the controller in this slot.

Action:

1.Be sure all cables are properly connected and working.

2.Be sure the controller is working, and replace if needed.

Controller Detected. NVRAM Configuration not Present

Description: EISA NVRAM does not contain a configuration for this controller.

Action: Run the server setup utility to configure the NVRAM.

Controller Firmware Needs Upgrading

Description: Controller firmware is below the latest recommended version.

Action: Update the controller to the latest firmware version ("Firmware maintenance" on page 65).

Controller is Located in Special "Video" Slot

Description: Controller is installed in the slot for special video control signals. If the controller is used in this slot, LED indicators on the front panel may not function properly.

Action: Install the controller into a different slot, and run the server setup utility to configure NVRAM. Then, run ACU ("Array Configuration Utility" on page 54) to configure the controller.

Controller Is Not Configured

Description: Controller is not configured. If the controller was previously configured and you change drive locations, a problem might exist with the placement of the drives. ADU ("Array Diagnostic Utility" on
