Send Diagnostic; Table 6-96 Send Diagnostic Command - Sun Microsystems storagetek sl500 Reference Manual

Send Diagnostic

The Send Diagnostic command (1Dh) requests the library to perform a self-
diagnostic test. The library may support some self tests in the future but for now
considers this command to be a no-operation.
The self-test includes initialization diagnostics and calibration of the library. The
extended diagnostics provide random cartridge motions and additional calibration
features.
The library disconnects while a diagnostic test is being performed, then reconnects
when the diagnostic test completes. This disconnected time can be several minutes,
and time- outs should be adjusted accordingly.
The library returns status based on the diagnostic test result. The Receive
Diagnostic command is not used.
