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. Changing the Default Battery Test Time 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. 5. In the Test Time box, enter the time of day that you want the test to start as follows: a. To set the hour, click on the hour and then use the up- and downarrows to set the value. b. To set the minutes, click on the minutes and then use the up- and downarrows to set the value. c. To set the test time to AM or PM, click AM or PM and then use the up- and downarrows to set the value. 6. Click OK to apply the changes and close the dialog box. Click Help in the dialog box to display descriptions of each property in the dialog box. 28 EMC CLARiiON CX300, CX500, and CX700 Initialization Guide
