Using The Dlt 8000 Tape System's Basic Health Check (Bhc) Test Feature - Quantum DLT 8000 Product Manual

Configuring, Installing, and Operating the Tape System
2.8 Using the DLT 8000 Tape System's Basic Health Check (BHC) Test
Feature
The BHC feature is provided for use only by a trained service provider.
The BHC test uses the tape system's firmware to check the various EEROM-based
information packets for log entries of events that have occurred in the previous 120
hours of operation. Based on that information, the system can report on its "health."
The test is pass/fail only.
You can invoke the BHC test three ways: via the tape drive's front panel, the system's
library port, or via the SCSI SEND DIAGNOSTIC command. This guide explains how
to run the BHC test via the front panel; note that the BHC test cannot be run if a
SEND DIAGNOSTIC command is in progress or if the BHC Test is already running.
Running the BHC Test Using the Front Panel
1. Press and hold the Density Select Button (Figure 13) for five seconds. The Density
Override Indicator (Figure 2-13) flashes for five seconds. After the five seconds, the
top two Density Indicators (Figure 2-13) will illuminate.
2. Release, then momentarily hold the Density Select Button. The top two Density
Indicators will flash, indicating that the BHC test is running. The two Density
Indicators continue to flash while the test proceeds.
1. If the Density Select Button is pressed and held for less than five seconds, the BHC test
will not run and the Density Indicators return to their original state.
2. If the Density Select Button is not released then momentarily pressed again, the BHC
test will not run and the Density Indicators return to their original state.
If the test passes, the top four Density Indicators illuminate steadily for five seconds,
then return to their original state.
If the test fails, the top four Density Indicators flash on and off for five seconds, then
return to their original state.
