Meaning of Library and Device Status Indicators in SLC
13-4 StorageTek SL8500 Library Guide
■ Warning — server is taking longer than 10 seconds to respond
■ Error — server is taking longer than 30 seconds respond
After about 30–60 seconds of lost communication with the library controller, the
heartbeat monitor turns gray, then red, and displays:
Heartbeat message not received from the library controller.
Log off the SLC and log on again to restore communication.
Health Status of the Library
The lower right of all SLC screens shows the library health status.
■ Normal — all library devices are functioning normally
■ Warning — one or more library devices is offline or operating in a degraded state
■ Error — one or more library devices has experienced a failure
After a device error is fixed, the library health indicator changes to "Warning". The
indicator will not change to "Normal" until the library is taken offline. If there are
multiple problems with a device or status alert condition, the health indicator
displays the most severe condition.
