The VERITAS Volume Manager ASL

VERITAS has provided an Array Software Library (ASL) that must be installed on the 
same host system as the Volume Manager 3.2 or 3.5 software to enable the software to 
recognize a FC or SATA array.

Battery Operation

The battery LED (on the far right side of the I/O controller module) is amber if the 
battery is bad or missing. The LED blinks green if the battery is charging and is solid 
green when the battery is fully charged. 

7.2.1

Battery Status

Battery status is displayed at the top of the initial firmware screen. BAT: status 
displays somewhere in the range from BAD to ----- (charging) to +++++ (fully 
charged).

For maximum life, lithium ion batteries are not recharged until the charge level is very 
low, indicated by a status of -----. Automatic recharging at this point takes very little 
time.

A battery module whose status shows one or more + signs can support cache memory 
for 72 hours. As long as one or more + signs are displayed, your battery is performing 
correctly.
