L700 with 12 x LTO3/FC FSC:3E05 2

[fumpel]

now we are seeing almost weekly drive failures on our Storagetek L700 with 12 LTO 3 drives
The drives come with the messages 3e0a and 3e05 in the FSC log, the display will show the message "not communicate". Switch off and on can reactivate the drives.
The losses are independent of the drive and securable to host, mainly occur in low volume of data backups and when the tape end is reached, or nearly complete.
the firmware of the drives is up to date
the Library is almost up to date (the penultimate state)
where can I find a list of FSC´s or meaning 3E05 and 3E0A?
Any ideas anyone?
Thank you in advance

What is the firmware level of the Library?

These codes mean:

3E05: Drive command already in progress.
Logical Error 99%

3E0A: TTI communication to drive failed.
Drive error 90%

It means the serial communication link between the L700 controller board and the LTO drives is failing. If it were just one drive you would suspect the drive, but if happenning on several drives it is more likely to be the controller board. You could try remove the metal shield over the controller board and check the plug where the comms cable leaves the controller and goes into the bulkhead.

In a single drive tower machine (drives 0-9) a short comms cable comes out of J24 on the top edge of the board. You have two drive towers so I think it is different. You will have an extra small PCB fitted over J241 which allows the controller to talk to the drives 10-19.

I have seen that error message... especially if u replaced a IBM LTO 2 FC with a HP LTO3 FC drive in the same slot (upgrade)...After a IPL the error message was gone, but the code level was on the latest of the L700. Make sure the library have the latest code...
