5.7 Enabling and Disabling the Battery

If you are not using a battery in your Galaxy 65 Subsystem, the Galaxy 65 Subsystem will sound an alarm. To eliminate the alarm, you can disable the battery. The default setting is battery enabled.

Notes	1	You should only disable the battery if you are running the Galaxy 65 Subsystem with an
		Uninterruptible power supply (UPS), so that you will not lose power to the Galaxy 65
		Subsystem.
	2	If you disable the battery, the Galaxy 65 Subsystem will not give any warnings, nor will it
		disable the write-back cache.
	3	If you change this setting, you must restart the Galaxy 65 Subsystem for the change to
		take effect.

To change the battery setting:

1From SAM, select Manage Galaxy 65 Subsystem > General Config > Option Configuration. The Option Configuration page displays.

2Select the Battery option you want.

3Click Change Options.

You must restart the Galaxy 65 Subsystem for the change to take effect.

4Select 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 Galaxy 65 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:

1From SAM, select Manage Galaxy 65 Subsystem > General Config > Option Configuration. The Option Configuration page displays.

2Select the Utility Priority option you want.

3Click Change Options.
