Agent information 38
• High—Indicates the rebuild priority is high.
• Unknown—Indicates that the rebuild priority is not recognized. You may need to upgrade the Storage
Agents.
• Expand Priority—D
isplays 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—D
isplays 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 upgrade the Storage
Agents.
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.
• Backup Power Status—Displays the status of the backup power source on the Array Accelerator. The backup
power source can recharge only when the system is powered on. Backup power sources include batteries and
capacitors.
• OK—The backup power source is fully charged.
• Failed, Replace Battery—The array controller has one or more array accelerator batteries that are failed.
Array accelerator operations such as Battery Backed Write Cache, Expansion, Extension, and Migration
are temporarily suspended until the batteries are replaced.
• Recharging—The array controller has one or more array accelerator backup power sources that are
recharging. Array accelerator operations such as Battery/Capacitor Backed Write Cache, Expansion,
