Hi,

I am having a problem with qlc driver on a V440 connected to a Tape Library
via a fiber switch.

The issue is that under I/O the QLC is getting Offline/Online which is
affecting the backup each time after this incident.

 

The following messages are produced on the System:

Is it a hardware problem? Or a driver problem?
