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.

1.In the Manager’s Enterprise Storage dialog box, click the Storage tab.
