NSR Reports shows "TWE OVERFLOW Detected" and Backup Error

NSR Reports shows "TWE OVERFLOW Detected" and Backup Error

Hello,
we use MSL5030 FC Libs with NSR 1200. When a Backup is running, there are some "TWE OVERFLOW Detected" Messages in 2 of the Library NSR Reports.
And sometimes the Backup Session (with Data Protector) run into I/O Error. The NSRs are connected to 4/8 SAN Switches.
Other Libraries - without the "TWE OVERFLOW Detected" - works fine.
Does anyone know what's wrong?
Thanks

First check the firmware for a current version.

To update (if needed) use LTT http://www.hp.com/support/tapetools or this file:

Hope this helps!

Hi,

You can try using a different SFPs and FC cables. This has resolved this issue for me some time back
