Adapter Menu
The options on the HP NetRAID Assistant Adapter menu are described below.
•
Update Firmware: This selection is not available.
•
Flush Cache: Writes all data in cache to physical drives. The
HP NetRAID system allows logical drives to be configured in write-back
mode. If configured in this mode, data is retained in cache and is not
immediately written to the physical drives. If your system is configured for
write-back mode, and if the adapter must be powered down rapidly, you
must flush the contents of the cache memory to preserve data integrity.
•
Performance Monitor On/Off: Displays a graphic representation of the
performance of the logical drive you select. To use this selection, first click
the left mouse button on a drive icon and then select Performance Monitor.
Performance for each logical drive is displayed in two ways: as the data
transfer rate and as the number of I/O operations per second. You can
choose different logical drives, the type of graph (bar or line), and the
window arrangement from the Performance Monitor menus.
•
Properties: Displays the adapter properties, including the firmware and
BIOS versions, the rebuild rate, and cache memory size.
•
Rebuild Rate: Sets the rebuild rate for rebuilding a failed drive. The
rebuild rate determines the percentage of IOP (input/output processor)
resources devoted to the rebuild. A 100% rebuild rate means that 100% of
the IOP’s resources are applied to the rebuild, leaving no resources
available for other tasks until the rebuild is complete. The default rebuild
rate is 50%.
•
Rescan: Reads the current configuration for the currently selected adapter.
It displays the updated configuration on the main window of HP NetRAID
Assistant. Use this selection if any physical drives were moved, added,
removed, changed, or whose state changed after HP NetRAID Assistant
was started.
