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.
— Redundant Size Mismatch—Cache operations are temporarily disabled. The cache sizes
on the redundant controllers do not match.
— Redundant Cache Failure—Cache operations are temporarily disabled. The cache on
the redundant controller has failed.
— Excessive ECC Errors—Cache operations have been permanently disabled. The number
of cache lines experiencing excessive ECC errors has reached a preset limit.
— ADG Enabler Missing—Indicates that write cache operations have been temporarily
disabled. An advanced data guarding logical drive is configured but the RAID ADG
Enabler Module is broken or missing.
— POST ECC Errors—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 the Power On Self Test (POST).
— Battery Hot Removed—Indicates that write cache operations have been permanently
disabled. The cache has been disabled because a battery has been hot removed.
— Capacitor Charge Low—Indicates that write cache operations are temporarily disabled
due to insufficient capacitor power.
— Not Enough Batteries Attached—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—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—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—Indicates that write cache operations have been permanently
disabled. The cache has been disabled because there are no capacitors attached to the
capacitor based cache module.
