Philip,

your understanding of CentricStor is right, it does all the stage and de-stage 
stuff for itself. Regarding the timeout: We get a tpError after magically 6 
(?!) minutes, regardless of the "media mount timeout" setting... I wonder where 
this 6 minutes come from! The tpError leads to one tape drive beeing downed, 
the mount request is transfered to a different drive where the mount normally 
succeeds, because all the content has been staged in by the CentricStor...

I wonder if this special timeout is really a NetBackup timeout or maybe a 
Windows timeout somewhere!?

Regards, 

Mirko
