/cx show rebuildmode
The /cx show rebuildmode command shows the current rebuild mode setting
of the specified controller. The rebuild mode has two settings: Adaptive and
Low latency.
Rebuild mode works with the rebuild task rate (see “/cx show rebuildrate” on
page 49).
The Adaptive setting is the default rebuild mode. It allows the firmware to
adjust the interaction of rebuild tasks with host I/Os to maximize the speed of
both host I/O and rebuild tasks. The Low latency setting minimizes latency
(delay) in reading data from a RAID unit by slowing the rebuild task process.
For some applications, such as video server applications and audio
applications, use the Low latency setting to minimize the latency of read
commands so that users do not perceive a lag when viewing video or listening
to audio.
For a more complete discussion of background task modes, see “Working
with the Background Task Mode” in the 3ware SATA+SAS RAID Controller
Card Software User Guide, Version 10.2.
Example:
//localhost> /c1 show rebuildmode
/c1 Rebuild background task mode = Low Latency
Related commands:
/cx set rebuildmode=<adaptive|lowlatency>
/cx set rebuildrate=<1..5>
/cx show rebuildrate
