Product: Vtrak 15100
Additional Description: When you modify the cache policy for a logical drive it does not allow you to select Writeback for the logical drive
Usually the problem is a bad battery, it is not charged or it is defective. Try reseating the cooling unit that houses the battery. Run a diagnostic on the battery using the CLI. Also check for amber or red LED's for the battery or the FRU status light.
Sometimes the enclosure will not detect the battery for at least 3 minutes so wait 3 minutes after turning the Vtrak on before you check the cache settings for the logical drive that way the enclosure will report accurately
