H.9 Changing the Utility Priority
You can change the priority at which all utilities (Verify, Reconstruct,
Expand, Initialize, etc.) run when there are active I/O operations
competing for the EF2800 system’s CPU. The choices are:
• High (default)
• Medium
• Low
For example, select High if your highest priority is to get the array back
to a fully fault-tolerant state. This causes heavy I/O with the host to be
slower than normal. Select Low priority if streaming data without
interruption, such as for a Web server, is more important than data
redundancy. This allows the Reconstruct or other utility to run at a
slower rate with minimal effects on host I/O.
To change the utility priority:
1.
From the System Menu, select
Configuration Menu
and press
< Enter>. The Configuration Menu displays.
2.
Select
Utility Priority
and press < Enter>. The Utility Priority screen
displays
(Figure 172)
. The current setting is marked with an * next
to it.
3.
Select the option you want and press < Enter>.
