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:
1 From SAM, select Manage Galaxy 65 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 Galaxy 65 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 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:
1
From SAM, select
Manage Galaxy 65 Subsystem > General Config > Option Configuration
.
The Option Configuration page displays.
2
Select the Utility Priority option you want.
