As you know, L20/40/60 tape jam issue had been troubling me for about
a month. The first case came from Jiangxi Unicom L60 and then came
from Anhui Mobile L40 and then Anhui Unicom L60. Fortunately, they are
calm again now with the help of ＸＸＸ and other bosses.
I'd like to share with you about the tape jam issue of L20/40/60.
Another good news, it said that L20/40/60 will EOL!! :-)Phenomena
====================
1. In the three cases, got the same error messages while tape jam:
Failed to unload tape from drive. Failed to detect that the transport
has a tape.
Code 63 Qualifier 48
sequence 126,129,105,104,127,130 2. Tape jammed in the driver, and could not be unloaded. Troubleshooting
====================
1. Please DO NOT try to unload tape by panel command or web page AGAIN
AND AGAIN, or the tape will be damaged.
2. Power cycle the library. Then try unload again. If it succeeded,
you are lucky boy. If the tape jam happen rarely, then close this case
and let it be. If not, go ahead.
3. Upgrade firmware of L20/40/60, if it is not the latest.The current
firmwares are 1.25S and 1.33S. 1.42S will be released. After the
library reboot, try unload again. If failed , go ahead.
NOTE: a)SAVE all the configuration and error messages via web. b)DO
FOLLOW the upgrading steps provied by patch 111972.
4. We had to manually eject jammed tape out of drive module. Please
follow these steps: a)Rewind the jammed tape via
maintenance->test->rewind. NOTE:PLEASE DO REWIND THE TAPE, or the tape
will be damaged by manually eject. b)Power off this tape library and
remove the drive module with jammed tape. c) Manually roll the gear of
the drive module to eject the tape. It's hard to description the
action. Please contact me if any confusion.
This step is very important, because in the process of
troubleshooting, we could had tape jammed many times. Exercise if
possible. 5. Try a good DLTIV tape. If you had such case, get the SONY DLT IV
tape from WANG Jian. If the tape you bring, succeed in
loading/unloading. And then you know how to talk with your cust about
this issue:). If failed, go ahead. 6. It's time to consider drive module replacement. Try other drive
module with the tape you bring if possible, before replacing drive
module. NOTE: Order one more drive module than you needed actually,
becuase the drive module is very possible FCO! If failed after drive
module replacement, go ahead. 7. Replace Library Controller Assembly/Vertical Lift Assembly/DLT
Picker Translate Assembly/ L20 Motherboard ONE BY ONE as you like.
NOTE:Please upgrade the firmware after your replacement. If failed, go
ahead. 8. Do not hesitate to Escalate. FRUs
