Setting Battery Test Time
Setting Battery Test Time
You can now set the battery test time, so that each week the SP runs a
battery self-test to ensure that the monitoring circuitry is working in
each standby power supply (SPS) or battery backup unit (BBU) of the
storage system. While the test runs, storage-system write caching is
disabled, but communication with the server continues. I/O
performance may decrease during the test. When the test is finished,
storage-system write caching is re-enabled automatically. The factory
default setting starts the battery test at 1:00 A.M. on Sunday, based on
the management station’s time zone. You can change this setting
using the procedure below.

To change the default battery test time, do the following:
1. In the Manager’s Enterprise Storage dialog box, click the Storage
tab.
2. Double-click the icons for the storage system and standby power
supply components in which the battery resides.
3. Right-click the battery component icon on which you want to set
the test time, and then click Set Test Time.
4. In the Test Day box, type or select the day of the week that you
want the test to run.
