LED3 pattern - - - - - One blink per second Steady glow One blink per second LED4 pattern One blink every two seconds Double blink, then pause One blink per second Steady glow Off One blink per second - - Interpretation The system is powered down, and the cache contains data that has not yet been written to the drives. Restore system power as soon as possible to prevent data loss. Data preservation time is extended any time that 3.3 V auxiliary power is available, as indicated by LED 2. In the absence of auxiliary power, battery power alone preserves the data. A fullycharged battery can normally preserve data for at least two days. The battery lifetime also depends on the cache module size. For further information, refer to the controller QuickSpecs on the HP website (http://www.hp.com). The cache microcontroller is waiting for the host controller to communicate. The battery pack is below the minimum charge level and is being charged. Features that require a battery (such as write cache, capacity expansion, stripe size migration, and RAID migration) are temporarily unavailable until charging is complete. The recharge process takes between 15 minutes and two hours, depending on the initial capacity of the battery. The battery pack is fully charged, and posted write data is stored in the cache. The battery pack is fully charged, and there is no posted write data in the cache. An alternating green and amber blink pattern indicates that the cache microcontroller is executing from within its boot loader and receiving new flash code from the host controller. There is a short circuit across the battery terminals or within the battery pack. BBWC features are disabled until the battery pack is replaced. The life expectancy of a battery pack is typically more than three years. There is an open circuit across the battery terminals or within the battery pack. BBWC features are disabled until the battery pack is replaced. The life expectancy of a battery pack is typically more than three years. Diagnostic tools Several diagnostic tools provide feedback about problems with arrays. The most important are: • ADU This utility is available on both the SmartStart CD and the HP website (http://www.hp.com/support). The meanings of the various ADU error messages are provided in the HP Servers Troubleshooting Guide. • POST messages Smart Array controllers produce diagnostic error messages at reboot. Many of these POST messages are self-explanatory and suggest corrective actions. For more information about POST messages, refer to the HP Servers Troubleshooting Guide. • Server Diagnostics Diagnosing array problems 35
