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.

7.2Battery 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.

7.2.1Battery 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.
