• Backup Power Status—Displays the status of the backup power source on the Array
Accelerator. The backup power source can recharge only when the system is powered on.
Backup power sources include batteries and capacitors.
— OK—The backup power source is fully charged.
— Failed, 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.
— Recharging—The array controller has one or more array accelerator backup power
sources that are recharging. Array accelerator operations such as Battery/Capacitor
Backed Write Cache, Expansion, 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
