Owner's manual

• Controller Status displays the status of the controller hardware. The following values are valid:
OK - The controller is operating normally.◦
◦ Failed - The controller has failed and is no longer operating.
◦ Offline - The controller is offline.
◦ Redundant Path Offline - There are multiple connection paths to this controller. At least
one connection path is available and at least one connection path is not available.
◦ Unknown - Indicates that the Storage Agents are unable to determine the status of the
controller. You may need to upgrade the Storage Agents.
• Current Role displays the array controller's current role for duplexed array controllers. The
following values are valid:
◦ Not Duplexed - This array controller is not duplexed.
◦ Active - This duplexed array controller is the active controller.
◦ Backup - This duplexed array controller is the backup controller.
◦ Unknown - Indicates that the Storage Agents are unable to determine the role of the
controller. You may need to upgrade the Storage Agents.
• Redundancy Type displays the type of redundant configuration. The following values are valid:
Not Redundant - This array controller is not in a redundant configuration.◦
◦ Firmware Active/Standby - The array controller is using an active/standby algorithm
implemented in the controller firmware and the operating system driver.
◦ Firmware Primary/Secondary - The array controller is using a primary/secondary algorithm
implemented in the controller firmware and the operating system driver.
◦ Unknown - Indicates that the Storage Agents are unable to determine the type of
redundancy for the controller. You may need to upgrade the Storage Agents.
• Redundancy Error displays the redundancy error for the controller. The following values are
valid:
◦ No Failure - No failures have been detected.
◦ No Redundant Controller - No redundant controller is installed.
◦ Different Hardware - The other controller indicates a different hardware model.
◦ No Link - A link to the other controller could not be established.
◦ Different Firmware - The other controller indicates a different firmware version.
◦ Different Cache - The other controller indicates a different cache size.
◦ Other Cache Failure - The other controller indicates a cache failure.
◦ No Drives - This controller cannot see any attached drives, but the other controller can.
◦ Other No Drives - This controller can see the attached drives, but the other controller
cannot.
◦ Unsupported Drives - One or more attached drives has been determined to be incapable
of properly supporting redundant controller operation.
◦ Expand in Progress - An expand operation is in progress. Redundant operation not
supported until the expand operation is complete.
◦ Unknown - Indicates that the Storage Agents are unable to determine the redundancy
error for the controller. You may need to upgrade the Storage Agents.
