3. To isolate the problem:
a. Re-save the configuration again. Because the configuration is already
apparently correct, re-saving the configuration again generates and
stores a new checksum.
If an unused bit of the RAM is bad, it is now included in the ASIA
checksum and does not show up again as an error.
b. Perform an IPL on the drive.
c. If the error is not repeated, it is indicated that an unused bit in the RAM is
bad. This problem can now be disregarded. Go to Step 5.
d. If the problem is repeated and the configuration remains correct, there
might be a problem with an unused bit in the EEPROM or the checksum
circuit.
4. If the client and drive configurations do not match, there are two possibilities:
a. A damaged used are of the RAM.
b. A damaged used area of the EEPROM.
Reconfigure the drive and save the new configuration.
•
If a used area of the RAM is bad, the save operation will fail, causing a
“Save Fails” error. In that case the “Fix_CfgErr” was caused by a bad RAM
and the drive must be replaced.
•
If the save operation succeeds, the EEPROM is probably bad. The new
configuration is properly saved only to the RAM: The EEPROM might have
corrupt data.
5. If applicable, place the drive back online.
6. If the configuration problem repeats on the next IPL, it means that the
EEPROM is damaged and the drive should be replaced.
Handling a UnWr xxxx Message
“UnWr xxxx” means unwritten data. This message can appear if the Unload
switch 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.
Note. When the configuration in the RAM is correct, the drive can usually operate
normally while it remains powered on even it the EEPROM or checksum circuit in the ASIA
are damaged.
Note. When the configuration in the RAM is correct, the drive can usually operate
normally while it remains powered on, even if the EEPROM is damaged.
