RS-1600-X24 User Guide

5.7 Enabling and Disabling the Battery

If you are not using a battery in your X24 Subsystem, the X24 Subsystem will sound an alarm. To
eliminate the alarm, you can disable the battery. The default setting is battery enabled.
Notes
To change the battery setting:
1 From SAM, select Manage X24 Subsystem > General Config > Option Configuration.
The Option Configuration page displays.
2 Select the Battery option you want.
3 Click Change Options.
You must restart the X24 Subsystem for the change to take effect.
4 Select Shutdown/Restart from the SAM menu.

5.8 Changing the Utility Priority

You can change the priority at which all utilities (Verify, Reconstruct, Expand, and Initialize) run when
there are active I/O operations competing for the X24 Subsystem'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 SAM, select Manage X24 Subsystem > General Config > Option Configuration.
The Option Configuration page displays.
2 Select the Utility Priority option you want.
3 Click Change Options.

1 You should only disable the battery if you are running the X24 Subsystem with an
Uninterruptible power supply (UPS), so that you will not lose power to the X24
Subsystem.
2 If you disable the battery, the X24 Subsystem will not give any warnings, nor will it disable
the write-back cache.
3 If you change this setting, you must restart the X24 Subsystem for the change to take
effect.
