Product: Vtrak 15100
Platform: Independent
Additional Description: When you modify the cache policy for a logical drive it does not allow you to select Writeback for the logical drive
Solution:
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.
Additional Information:
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
