write-back-
status
string The current, system-wide cache policy as determined by auto-write-through
(AWT) logic. This value is not settable by users. If an AWT trigger condition
(such as a CompactFlash failure) is met, the cache policy for all volumes
changes to write-through, overriding the volume-specific settings. When the
problem is corrected, the cache policy reverts to the value configured for each
individual volume.
• Enabled: Write-back. This is the normal state.
• Disabled: Write-through.
• Not up: The controller is not up.

temporarily disabled during controller shut down.
