Batteries
The RAID controllers in the VTrak subsystem use a battery for backup power to
protect data in the cache. Should a power failure occur, the battery enables the
cache to hold data up to 72 hours. The battery recharges during normal
subsystem operation.
In most cases, installing a replacement battery corrects a marginal or failed
condition. The battery is located inside the RAID controller housing. You can
remove and replace the battery without removing the RAID controller. The battery
is hot-swappable.
No tools are required for the procedure. See “Replacing a Cache Battery” on
page 265.
Also see “Reconditioning a Battery” on page 128 or page 183.
