Verifying component failure Before replacing a battery, use the following methods to verify the component failure: CAUTION: If Command View EVA does not present a status consistent with that of the battery status indicator, or if Command View or the System Event Analyzer indicates multiple hardware failures, contact HP support for assistance. The HP support web site is located at http://www.hp.com/support • Analyze any failure messages you may have received from system monitoring (System Event Analyzer). • Check status using Command View EVA: CAUTION: If you are running HP StorageWorks Command View EVA 4.0, the battery numbering presented in the management interface is inconsistent with the numbering used in the storage system and reported by the ISEE/WEBES monitoring tool. HP Command View EVA 4.0 identifies the top battery as 1 and the bottom battery as 2. The correct numbering should be 0 and 1 respectively. Remember to make this conversion when replacing a battery. This inconsistency is corrected in later versions of HP Command View EVA. 1. In the Navigation pane, select Storage system > Hardware > Rack > Controller enclosure > Controller. 2.
