Expand Priority—Displays the logical drive expand priority of the controller. The following
values are valid:
— Low—Indicates the expand priority is low.
— Medium—Indicates the expand priority is medium.
— High—Indicates the expand priority is high.
— Unknown—Indicates that the expand priority is not recognized. You may need to

upgrade the Storage Agents.

Number of Ports—Displays the number of usable SCSI ports on the controller. Sometimes
port is also referred to as bus or channel. The number of ports does not indicate the number
of connectors.

Internal SAS Ports—Displays the number of internal SAS connectors on the controller.

External SAS Ports—Displays the number of external SAS connectors on the controller.

Physical Drive Write Cache State—Displays the controller setting for physical drive write
cache. The following values are valid:
— Disabled—Indicates the controller will disable write cache on all physical drives.
— Enabled—Indicates the controller will enable write cache on all physical drives.
— Unknown—Indicates the drive write cache state is not recognized. You may need to

Array Accelerator Information

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

Status—Displays the status of the array accelerator. 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

Array Accelerator 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

Array Accelerator Error Code for the monitored item to determine why the cache
operations have been disabled.

— Unavailable—An Array Accelerator has not been configured.
— Unknown—The Storage Agents cannot determine the status of the Array Accelerator.

You may need to upgrade the Storage Agents.

Bad Data—Indicates the possibility of data loss due to a battery problem when the system
was powered on. The following values are valid:
— Possible—At power-on, the battery pack was not sufficiently charged. Because the

battery pack did not retain sufficient charge when the system resumed power, the Array
Accelerator has not retained any data that may have been stored in the cache. If no data
was in the cache, no data was lost. Several situations may have caused this condition:

If the system was without power for eight days, and the battery pack was on (the
battery pack activates only if the system loses power unexpectedly), any data that
may have been stored was lost.

There may be a problem with the battery pack. See the Battery Status monitored
item for more information.

The Array Accelerator board has been replaced with a new board that has a
discharged battery pack. In this case, no data is lost. Posted reads and writes are
automatically enabled when the battery pack reaches full charge.

— None—No data loss occurred. At power up, the battery pack was properly charged.
— Unknown—The Storage Agents do not recognize the status. You may need to update

your software.
