Error Code—Displays the status of the cache operations. The following values are valid:
None—Cache operations are currently configured and enabled for at least one logical
drive. No cache errors have occurred. ◦
◦ Bad Configuration—Cache operations are temporarily disabled. This error could be
caused if the Cache Module was switched from one controller to another. Schedule
maintenance time to ensure that the board has been properly configured for this system.
NOTE: If data from another system was stored on the board, you must reconfigure it.
Reconfiguring the board destroys any stored data.
◦ Replace Battery—The array controller has one or more array accelerator batteries that
are failed. Cache Module operations such as Battery Backed Write Cache, Expansion,
Extension and Migration are temporarily suspended until the batteries are replaced.
Consult the user guide to learn how to identify and replace failed batteries.
◦ Low Battery—The array controller has one or more array accelerator batteries that are
recharging. Cache Module operations such as Battery Backed Write Cache, Expansion,
Extension and Migration are temporarily suspended until the batteries are fully charged.
Cache Module operations automatically resume when charging is complete.
◦ Disable Command Issued—Cache operations are temporarily disabled. This condition
should not exist when the system regains power.
◦ No Resources—Cache operations are temporarily disabled. The controller does not have
sufficient resources to perform cache operations. For example, when a replaced drive is
being rebuilt, there are not sufficient resources. Once the operation that requires the
resources has completed, this condition clears and cache operations resume.
◦ Not Connected—Cache operations are temporarily disabled. The Cache Module has
been configured but is not currently attached to the controller. Check the alignment of
the board and connections.
◦ Bad Mirror Data—Cache operations have been permanently disabled. The Cache Module
stores mirrored copies of all data. If data exists in the cache when the system is first
powered up, the Cache Module performs a data compare test between the mirrored
copies. If the data does not match, an error has occurred. Data may have been lost and
the board may need servicing.
◦ Read Failure—Cache operations have been permanently disabled. The Cache Module
stores mirrored copies of all data. While reading the data, memory parity errors occurred
so both copies were corrupted and cannot be retrieved. Data has been lost. Have the
board serviced.
◦ Write Failure—Cache operations have been permanently disabled. This error occurs
when an unsuccessful attempt was made to write data to the Cache Module. 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. Have the board serviced.
◦ Configuration Changed—Cache operations have been permanently disabled. The
configuration of the logical drives has changed. Re-configure the Cache Module.
◦ Transformation in Progress—Cache operations are temporarily disabled due to a logical
drive transformation (expansion, shrinkage or movement), in progress. When the
transformation operation completes, the accelerator will be enabled.
◦ Snapshot in Progress—Cache operations are temporarily disabled due to snapshot
operation that is in progress. When the snapshot operation completes, the accelerator
will be enabled.
