Cache Module Board Error Code.

Use this to determine the status of the write cache operations.

The status can be:

Other (1) Indicates that the instrument agent does not recognize the error code. You may need to update your software.

Invalid (2) Indicates that write cache operations are currently configured and enabled for at least one logical drive. No write cache errors have occurred.

Bad Configuration (3) Indicates that write cache operations are temporarily disabled. The Cache Module board was configured for a different controller. This error could be caused if boards were switched from one system to another. Rerun the configuration utility and ensure that the board has been properly configured for this system. Note: If data from another system was stored on the board, running configuration utility will cause the data to be lost.

Low Battery Power (4) Indicates that write cache operations are temporarily disabled due to insufficient battery power. Please view the Battery Status object instance for more information.

Disable Command Issued (5) Indicates that write cache operations are temporarily disabled. The device driver issues this command when the server is taken down. This condition should not exist when the system regains power.

No Resources Available (6) Indicates that write cache operations are temporarily disabled. The controller does not have sufficient resources to perform write cache operations. For example, when a replaced drive is being rebuilt, there will not be sufficient resources. Once the operation that requires the resources has completed, this condition will clear and write cache operations will resume.

Board Not Connected (7) Indicates that write cache operations are temporarily disabled. The Cache Module board has been configured but is not currently attached to the controller. Check the alignment of the board and connections.

Bad Mirror Data (8) Indicates that write cache operations have been permanently disabled. The Cache Module board stores mirrored copies of all data. If data exists on the board when the system is first powered up, the board performs a data compare test between the mirrored copies. If the data does not match, an error has occurred. Data may have been lost. Your board may need servicing.

Read Failure (9) Indicates that write cache operations have been permanently disabled. The Cache Module board stores mirror copies of all data. While reading the data from the board, memory parity errors have occurred. Both copies were corrupted and cannot be retrieved. Data has been lost, and you should service the board.

Write Failure (10) Indicates that write cache operations have been permanently disabled. This error occurs when an unsuccessful attempt was made to write data to the Cache Module board. Data could not be written to write cache memory in duplicate due to the detection of parity errors. This error does not indicate data loss. You should service the Cache Module board.

Config Command (11) Indicates that write cache operations have been permanently disabled. The configuration of the logical drives has changed. You need to reconfigure the Cache Module board.

Expand in Progress (12) Indicates that cache operations are temporarily disabled due to an expand of a logical drive. When the expand operation completes, the cache module will be enabled.

Snapshot In Progress (13) Indicates that cache operations are temporarily disabled due to a snapshot operation that is queued up or in progress. When the snapshot operation completes, the cache module will be enabled.

Redundant Low Battery (14) Indicates that cache operations are temporarily disabled. The redundant controller has insufficient cache battery power.

Redundant Size Mismatch (15) Indicates that cache operations are temporarily disabled. The cache sizes on the redundant controllers do not match.

Redundant Cache Failure (16) Indicates that cache operations are temporarily disabled. The cache on the redundant controller has failed.

Excessive ECC Errors (17) Indicates that write cache operations have been permanently disabled. The number of cache lines experiencing excessive ECC errors has reached a preset limit.

RAID ADG Enabler Module Missing (18) Indicates that write cache operations have been temperarily disabled. A RAID ADG logical drive is configured but the RAID ADG Enabler Module is broken or missing.

Power On Self Test (Post) ECC Errors (19) Indicates that write cache operations have been permanently disabled. The cache has been disabled due to a large number of ECC errors detected while testing the cache during Power On Self Test (Post).

Backup Power Source Hot Removed (20) Indicates that write cache operations have been permanently disabled. The cache has been disabled because a backup power source has been hot removed.

Flash Backed Cache Module Capacitor Charge Low (21) Indicates that write cache operations are temporarily disabled due to insufficient capacitor power.

Not Enough Batteries (22) Indicates that write cache operations have been permanently disabled. The cache has been disabled because there are not enough batteries attached to the controller to ensure write cache will be held without power for the advertised length of time.

Cache Module Not Supported By Firmware (23) Indicates that write cache operations have been permanently disabled. The cache has been disabled because the current cache module is not supported by the currently running firmware.

Battery Not Supported (24) Indicates that write cache operations have been permanently disabled. The cache has been disabled because one or more attached batteries are not supported by the currently running firmware.

No Capacitor Attached (25) Indicates that write cache operations have been permanently disabled. The cache has been disabled because there are no capacitors attached to the flash backed cache module.

Flash Backed Cache Module Backup Failed (26) Indicates that write cache operations have been permanently disabled. The cache has been disabled because the flash backed cache module backup operation has failed.

Flash Backed Cache Module Restore Failed (27) Indicates that write cache operations have been permanently disabled. The cache has been disabled because the flash backed cache module restore operation has failed.

Flash Backed Cache Module Hardware Failure (28) Indicates that write cache operations have been permanently disabled. The cache has been disabled because the flash backed cache module has encountered a hardware failure.

Capacitor Failed To Charge (29) Indicates that write cache operations have been permanently disabled. The cache has been disabled because the flash backed cache module capacitor has failed to charge.

Flash Backed Cache Module Memory Being Erased (30) Indicates that write cache operations have been temporarily disabled. The cache has been disabled because the flash backed cache module is erasing its flash memory.

Incompatible Cache Module (31) Indicates that write cache operations have been permanently disabled. The cache has been disabled because an incompatible cache module is being used.

Flash Backed Cache Module Charger Circuit Failure (32) Indicates that write cache operations have been permanently disabled. The cache has been disabled because the charger circuit on the flash backed cache module has failed.
