OID (symbolic): CPQIDA-MIB::cpqDaCntlrDriveWriteCacheState
OID (numeric): 1.3.6.1.4.1.232.3.2.2.1.1.27

Description: Array Controller Drive Write Cache State.
This is the controller's drive write cache setting. The following values are valid:
other (1) Indicates that the instrument agent does not recognize the value. You may need to upgrade the instrument agent.
disabled (2) The controller will disable drive write cache for all drives.
enabled (3) The controller will enable drive write cache for all drives.
What is cpqDaCntlrDriveWriteCacheState?
This enumerated value reports whether the controller has drive-level write caching enabled(3) or disabled(2) for all attached drives. An admin checks this because enabling drive write cache can boost performance but increases risk of data loss on power failure without adequate battery backup. For example, an admin finding cpqDaCntlrDriveWriteCacheState set to enabled on a controller without a battery-backed cache module may choose to disable it to protect data integrity.
