Description: Logical Drive WriteBack Cache.
The state of the writeback cache for the associated logical drives.
What is cpqSMALogicalDiskWriteBackCache?
This object reports whether writeback caching is enable(1), disable(2), or unknown(3) for this logical disk. Writeback caching acknowledges writes to the host as soon as they hit cache rather than waiting for disk, improving write performance but creating a data-loss risk if the cache isn't battery-backed during a power failure. An admin weighing performance against risk on a critical database volume would check this setting alongside the controller's battery charge state.
