Sun StorEdge™L7 Decision Tree
The purpose of the Sun StorEdge L7 Decision Tree is to identify a logical sequence of events to
troubleshoot a Sun StorEdge L7 autoloader based upon the error message displayed on the LCD.
Since there are no Field Replaceable Unit (FRU) items available for servicing a StorEdge L7
autoloader , failure to successfully clear the error message after performing the steps outlined in
this decision tree will result in autoloader replacement.

the selected storage slot and retrying the autoloader operation. An obstructed slot sensor (dust, lint, etc.
blocking the slot sensor) can also cause this error, as the autoloader will attempt to get a tape that isn’t
really there. Troubleshooting should continue with confirming the storage slot is empty, and if confirmed,
using compressed air to remove dust/debris from the slot sensor.
