Changing the Rebuild Priority setting
The Rebuild Priority setting determines the urgency with which the controller treats an internal command to
rebuild a failed logical drive.
•
At the low setting, normal system operations take priority over a rebuild.
•
At the medium setting, rebuilding occurs for half of the time, and normal system operations occur for the
rest of the time.
•
At the medium high setting, rebuilding is given a higher priority over normal system operations.
•
At the high setting, the rebuild takes precedence over all other system operations.
If the logical drive is part of an array that has an online spare, rebuilding begins automatically when drive
failure occurs. If the array does not have an online spare, rebuilding begins when the failed physical drive
is replaced.
Syntax
<target> modify rp=high|mediumhigh|medium|low|?
where <target> is a controller.
Example command
=> ctrl slot=3 modify rp=high
Changing the Expand Priority setting
The Expand Priority setting determines the urgency with which the controller treats an internal command to
expand an array.
•
At the low setting level, normal system operations take priority over an array expansion.
•
At the medium setting, expansion occurs for half of the time, and normal system operations occur for the
rest of the time.
•
At the high setting, the expansion takes precedence over all other system operations.
Syntax:
<target> modify ep=high|medium|low|?
where <target> is a controller.
Example command:
=> ctrl slot=3 modify ep=high
Setting the surface scan mode
The surfacescanmode keyword sets the surface mode for the controller. The available modes are disable,
high, or idle. If you specify the idle mode, you must also specify a surface scan delay value.
Syntax:
<target> modify [ surfacescanmode=disable | idle | high | ? ]
Example commands:
controller slot=1 modify surfacescanmode=high
controller slot=1 modify surfacescanmode=disable
controller slot=1 modify surfacescanmode=idle surfacescandelay=3
