7.1.5 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.
7.2 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.
