MSL6000 Drives going down

New to the world of tapes so excuse my ignorance...
I have NetBackup 6.5.3 running with 5 MLS6000 tape libraries.
Recently the drives in all of the libraries will not stay up for an extended period of time, sometimes they will go down within hours, and some times minutes of 'upping' the drive.

As far as I know, nothing has changed within the system. How do I even begin to troubleshoot this error?

Re: MSL6000 Drives going down

This looks like a classic sign of polling on tape drives.

What is the OS on the server?
If it is windows 2003 I suggest going to microsoft website and looking up article: KB842411 and following the registry fix. Also make sure that you backup your registry before running this fix. Also in services.msc panel of the server please disable and stop "Removable Storage" if not already done so.

Update the regular things like Firmware / Drivers and Storport.
