UnWr xxxx Indication
7-12 Sixth Edition 95741
■
UnWr xxxx Indication
U nWr xxxx means Unwritten Data. This message will display if the Unload
switch (6, Figure 7-1 on page 7-1 ) was pressed during a write operation. It
indicates that the drive attempted to write the remaining data before it unloaded
but the attempt failed and some data remains unwritten to tape.
CAUTION:
Pressing the Unload switch again will cause loss of this data.
The host may save the unwritten data by issuing the following command
sequence before pressing the
Unload switch a second time: “ Recover Buffer
Data .”
■
DumpAgain? Indication
The “ DumpAgain? ” display alternates with a “ CHK xxxx ” fault symptom code
indication while the service indicator (1, Figure 7-1 on page 7-1 ) flashes. This
occurs when the identical “ CHK xxxx ” fault symptom code is detected within
one minute. The drive then becomes non-operational and requires manual
intervention.
With this condition, you may choose to initiate a dump but there is no
requirement to do so. If you have reason to initiate the dump, press any control
except the
IPL switch (2, Figure 7-1 on page 7-1 ). This saves the dump data to
the EEPROM.
While the dump is being saved to the EEPROM, the service indicator goes out
and the display alternates between “ SavingDmp ” and the “ CHK xxxx ” display.
After saving, the drive automatically performs an IPL.
Use the procedures in Chapter 4, “Getting Started,” to copy the dump data from
EEPROM to tape or a file.
If you do not want to initiate the dump, press the IPL switch. This initiates an
IPL of the drive without copying the dump data to EEPROM.
If the IPL fails, as indicated by any error message, replace the drive.
If the IPL is successful, continue with normal operations.
