◦ RAID Stack Version—lists the RAID stack version operating the B-series array controller.

This value may change when upgrading or downgrading the operating system device

driver.

◦ Option ROM Version—lists the option ROM revision of the chipset or HBA being used by

the B-Series controller.

◦ HBA Firmware Version—lists the firmware revision of the chipset or HBA being used by

the B-Series controller.

◦ HBA Mode Option ROM Version—lists the revision of option ROM that would run on this

chipset or HBA (being used by the B-Series controller), if it were to run in HBA mode.

Cache Module / Status Information

Select the cache module item from the Mass Storage submenu to display the following information:

NOTE: For some controller models, a cache module board that physically attaches to the controller

or chipset may not be an available option. For these configurations, the Storage Agent will continue

to populate fields that are related to read caching operations.

• Status—Displays the status of the cache module and/or cache operations. The following values

are valid:

◦ Enabled—Cache operations are currently configured and enabled for at least one logical

drive.

◦ Temporarily Disabled—Cache operations have been temporarily disabled. Check the

Cache Module Error Code for the monitored item to determine why the cache operations

have been temporarily disabled.

◦ Permanently Disabled—Cache operations have been permanently disabled. Check the

Cache Module Error Code for the monitored item to determine why the cache operations

have been disabled.

◦ Cache Module Flash Memory Not Attached—The flash memory component of the flash

backed cache module is not attached. This status will be set when the flash memory is

not attached and the Supercap is attached. This value is only used on flash backed cache

modules that support removable flash memory.

◦ Cache Module Degraded—Failsafe Speed—The cache module board is currently degraded

and operating at a failsafe speed. View the cache memory fields Data Width and

Transfer Rate to obtain the cache module board's current memory data width and

memory transfer rate.

◦ Cache Module Critical Failure—The cache module board has encountered a critical failure.

The controller is currently operating in Zero Memory Raid mode.

◦ Read Cache Could Not Be Mapped—The read cache memory in a split cache configuration

could not be mapped by the operating system and as a result is not available. This status

may be caused by virtual space limitations in certain operating systems and is only

applicable to B-Series controllers.
