failed-over	string	Indicates whether the partner controller has failed over to this controller. No: The partner controller has not failed over to this controller. Yes: The partner controller has either failed or been shut down, and its responsibilities have been taken over by this controller. There will be a delay between the time that the value of the status property becomes Down for one controller and the time that the value of the failed-over property becomes Yes for the other controller. This time period is the time that it takes for a controller to take over the responsibilities of its partner.

multicore	string	Shows whether the controller module is using multiple application processing cores. Enabled: Multiple cores are active. Disabled: A single core is active.
multicore-numeric	uint32	Numeric equivalents for multicore values. 0: Enabled 1: Disabled
sc-cpu-type	string	Storage Controller processor type.
sc-cpu-speed	uint32	Storage Controller processor speed.
internal-serial-number	string	Internal serial number of the controller.
cache-lock	string	Shows whether hosts are prevented from using the SCSI MODE SELECT command to change the write-back cache setting of the storage system. No: Hosts are permitted to disable write-back cache. Yes: Hosts are prevented from disabling write-back cache.
cache-lock-numeric	uint32	Numeric equivalents for cache-lock values. 0: No 1: Yes
write-policy	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 fan 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. write-back: This is the normal state. write-through Not up: The controller is not up.
write-policy-numeric	uint32	Numeric equivalents for write-policy values. 0: write-back 1: write-through 2: Not up

redundancy-mode	string	The operating mode of the sytem, also called the cache redundancy mode. Deleted point Active-Active ULP: Both controllers are active using ULP (Unified LUN Presentation). Data for volumes configured to use write-back cache is automatically mirrored between the two controllers to provide fault tolerance. Single Controller: The enclosure contains a single controller.

In single-controller mode, the controller is operational. Down: This controller is not operational. Unknown: Status information is not available.
redundancy-status-numeric	uint32	Numeric equivalents for redundancy-status values. 0: Operational but not redundant 2 : Redundant 4: Down 5: Unknown
