YES, Davina matches exactly the point
(which she does most of the time :-)
[ enjoy your postings very much -sg-]

**blush**

Persistent binding would only help, if NetWorker
could work with physical addresses like [email protected].

Persistent binding does help, sorry if I implied that it doesn't.Persistent binding is a "good thing" and should always be used. Itreduces the problem and prevents devices from moving around due topurely SAN related issues, it just doesn't solve the whole problem.

Unfortunately it could not, or could it? [ TSM can :-(  ]

I heard some years ago about a new feature of 7.x that Legato called"device serialisation". I am still unclear what this feature actuallyoffers and how it can be used. Does anyone know?

Changing the OS type is NOT an option,
because investment in 250++ servers (many 4-/8-way) is already huge.

Fair enough, and Windows is a fully supported platform that should bepossible to configure for tape devices in s stable manner.

So I'm still looking for other Wintel NetWorkers
who have to deal with the problem and have found ways to ease the pain abit.

This is in fact a Microsoft problem, but it ought to be possible for EMCto come up with a robust solution to it. You have hit the nail on thehead in your last message, we need to be able to configure tape devicesin NetWorker based on their SCSI addresses rather than via the ratherflaky method of using Windows device names such as \\.\Tape0. I don'tthink this is possible using current NetWorker releases, perhaps EMCshould be looking at this for a future version. I would _love_ to beproved wrong on this issue....
