Resetting the Battery Age

The system tracks the installation date for each battery installed. The date is not the same as the date of manufacture. Every day the storage subsystem controllers compare the current date to the installation date for each battery. When a battery reaches the expiration age, a warning that the a cache battery has expired alerts the system administrator. When you replace a battery, you must set the installation date to the current date by resetting the battery age.
  1. Click the controller module components icon to view the battery age.
  2. Click the battery icon to view individual batteries. If you have replaced a battery, click Reset to reset the battery age.

    When a controller is replaced, the battery installation date and the expiration age are restored from the controller NVSRAM mirror metadata stored on the disk drives. If the battery is replaced at the same time, reset the battery age.

    If you do not have smart batteries, the Battery Settings dialog will not show learn cycles. Resetting the battery age is the only available option.
