the front of the library.
Figure 4 (Page 1 of 2). Start—All Library Models
If You Are Here For This Reason Perform This Action
Are you repairing a drive-only model without a
library? Go to Figure 3 on page START-4.
FID is displayed on the library operator panel display,
in the Error/FID log, or in a host error log entry. Go to Figure 8 on page START-12 to fix the fault.
ATTENTION DRIVE message on library operator panel
display or in the error log. Go to “Attention Drive Messages” on page START-24
for further isolation.
ATTENTION LIBRARY message on library operator
panel display or in the error log. Go to “Attention Library Messages” on
page START-25 for further isolation.
RECOVER status on library operator panel display. Go to “Clearing Tape Drive Recover Status” on
page PROC-35.
Library operator panel display hangs with two dark
lines across the display. The library LEDs may or may
not be flashing.
Note: This is normal for the first 30 seconds during
bring-up. If it hangs in this condition, the
machine has a problem.
Go to “Other Obvious Symptom Problems: MAP” on
page MAPS-21 to perform further problem
determination.
Library operator panel display is blank or partial
characters are indicated. Go to “Library Operator Panel Problems: MAP” on
page MAPS-3 for further isolation.
Some or all the LEDs fail to light on the front panel of
a library machine. Go to “Library LED Problems: MAP” on page MAPS-5
for further isolation.
You have no FID number and there are no indicators
lighted. Looks like power is missing from some or all
components. Go to “Power Problems: MAP” on page MAPS-13
and perform further problem determination.
A host or channel detected problem. (No FID
message) 1. Run the Verify Fix diagnostics using a scratch
cartridge to test the Read/Write function. See “CE
Verify Fix on Library Models” on page PROC-13. If
Verify Fix fails, use the FID to repair the drive.
2. If you have a SCSI Wrap Tool available, perform
“SCSI Port Wrap Test” on page PROC-84.
3. Verify that the SCSI address is set correctly. See
“Setting the SCSI Address and Configuring the
Library” on page INST-46.
You have a Model B02, B12 or B22 and the beginning
of line three of the library operator panel display
indicates an “N”, or the library does not recognize that
drive 2 is installed in the library. Go to “Isolate Drive 1 or Drive 2 Communications
Fault” on page PROC-43.
The tape drive status “INIT” is displayed on the
operator panel for more than 5 minutes. Go to “Isolate Drive 1 or Drive 2 Communications
Fault” on page PROC-43.
The Bar Code Reader feature is installed and the host
displays a message that states:
The cartridge cannot be found.
The Volume ID does not match.
Incorrect volume mounted in drive.
Go to “Resolving a Mismatch Between the Bar Code
Label and VOLSER” on page PROC-33
