Agent information 39
Extension, and Migration are temporarily suspended until the backup power source is fully charged. Array
accelerator operations will automatically resume when charging is complete.
• Degraded—The battery pack is still operating, but one of the batteries in the pack has failed to recharge
properly. Your board should be serviced as soon as possible.
• Not Present—A backup power source is not present. (Some controllers do not have a battery/capacitor-
backed cache).
• Failed, Replace Capacitor—The capacitor is below the sufficient voltage level and has not recharged in 10
minutes. Your Array Accelerator board needs to be serviced. Array accelerator operations such as
Capacitor Backed Write Cache, Expansion, Extension, and Migration are temporarily suspended until the
capacitor is replaced.
• Unknown—The Storage Agents do not recognize the backup power status. You may need to update your
software.
• 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 Array
Accelerator 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. Array
accelerator 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. Array
accelerator operations such as Battery Backed Write Cache, Expansion, Extension and Migration are
temporarily suspended until the batteries are fully charged. Array accelerator 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 Array Accelerator 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 Array Accelerator stores
mirrored copies of all data. If data exists in the cache when the system is first powered up, the Array
Accelerator 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 Array Accelerator 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 Array Accelerator. 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. Reconfigure the Array Accelerator.
• 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 a logical drive transformation
(expansion, shrinkage or movement), in progress. When the transformation operation completes, the
accelerator will be enabled.
• Redundant Low Battery—Cache operations are temporarily disabled. The redundant controller has
insufficient cache battery power.
