Rebuild Priority — High
Rebuild priority can be set to high, medium, or low. When the
rebuild request is set to high, the rebuild I/O request gets high
priority in the execution order.
When the rebuild request is set to medium in a heavily loaded
system (with a medium rate of system I/O requests), the
medium-priority rebuild can reduce the disk rebuild time at the
expense of degraded handling of I/O requests.
When the rebuild priority is set to low, in a moderate to heavily
loaded system, low rebuild priority will increases the disk
rebuild time but provides better system performance.
Note: Rebuild priority can be changed without affecting data in
the logical drives.
Ÿ Unattended Mode — Off
You can enable the adapter to accept changes in the
configuration without user input. Unattended mode is useful
when the server operates remotely. See “Unattended Mode of
Operation” on page 123 for more information.
When Unattended Mode is On, and a hard disk drive is found
in a location other than the one defined in the adapter
configuration, the program pauses briefly for user input, then,
automatically rearranges the configuration information to correct
the logical drive configuration. Unattended mode also clears
any locked stripes and any blocked drives.
When Unattended Mode is Off, the program waits for user
input.
