MSL6030 with LTO-2 and LTO-4 and failed backup?

[it61066]

We have upgraded an MSL6000 with one LTO-2 drive as follow:

- Adding e1200-320 4GB controller
- Adding LTO-4 (1840) drive and connecting to the second port (port-1) on the e1200-320 then terminating on the drive.

Initially the MSL was connected to the SAN using an old e1200 controller and everything was OK with Backup Exec 11d.

A FW upgrade for the library, e1200, LTO-4 has been performed (LTO-2 still as it was before)

Now, LTO-2 drive is working properly but the LTO-4 starts the backup (around 500MB) then fails.

Any idea please!!!

the LTO4 drive cannot write to a LTO2 media, its read only situation here.

Hi,

U can check this issue by upgrading FW of LTO4 and clean the drive , if problem not solved u can replace this drive for checking this issue.

You'll need to verify the drive is faulty using the drive assessment test in LTT if you're looking to replace the drive.

You can also pull a full support ticket (will get the library and both the drives) and post here and we can take a look see what condition it's all in. Should also be able to see what caused the backup to fail from the drive logs.

You will need to match the media - or at least use LTO 3 in your LTO 4 drive - as mentioned.

What is the failure message? The applications tend to blame the drive whatever goes wrong which is not very helpful.
