The Write-Back cache setting is configurable on a per array basis.
Setting to the default value means the array setting is coordinated
with the controller’s general setting. The controller’s general setting
option can be found in “View and Edit Config Parms” -> “Caching
Parameters” -> “Write-Back Cache”. Note that cached writes are
lost if power failure should occur unless cached data has been
duplicated to a partner controller and a battery is supporting cache
memory.
