CHAPTER 5: Using Your Tape Drive
5.1 Power On Self Test
When power is applied to the tape system, the system performs a Power On Self
Test (POST). POST completes in approximately ten seconds. While POST is
running, the tape system responds BUSY to SCSI commands. The tape system
also responds to various SCSI messages during POST.
During this time, if a host tries to negotiate Synchronous or Wide transfers, the
tape system will negotiate to Asynchronous or Narrow. It may take longer than the
duration of POST for the drive to become ready.
5.2 Performing a Trial Back-up
Complete the following steps to perform a trial back-up and verify the tape drive
has been correctly installed:
•
Insert a cartridge. Push the cartridge completely into the system. The tape will
load automatically.
•
Choose a sample file set from the host computer.
•
Perform a back-up and then restore the file set. The system has been correctly
installed if the back-up is completely restored without any errors. If you
experience errors, doublecheck the drive’s configuration and setup, using the
ideas provided in
“Troubleshooting” on page 5-13 . After you have exhausted
all troubleshooting alternatives, contact your service representative.
•
Press the Eject button to unload the cartridge. If you are unsure which button
is the Eject button, refer to
Figure 5-1 on page 5-11 .
Table 5-1. Indicator Pattern During POST
Stage What Can Be Observed

2 The red and yellow LEDs are extinguished and the green LED
flashes until POST completes.
3 If POST fails, the green and yellow LED will illuminate
steadily and the red LED will blink.
