scanner question, about tapes from a foreign Networker server

Posted by Michael Leone 
So I have to scan some tapes made on a foreign Networker server (Networker
v7.6 or something, that was on an old server of ours that no longer
exists). So I finally got an old tape drive (these are LTO-3 tapes), and I
loaded it on a storage node. And I am running "scanner -m".

And it is saying things like

ssid xxxx, 15MB, 1 file
Could not create saveset for ssid xxxx

Now, there are hostnames on that tape that aren't on my Networker server.
I'm assuming that's what it's referring to. But what I thought I could do
would be to do an mminfo query on the contents on that tape, get the
client names and client IDs that are on that tape.
Create a new clients on my current Networker server that correspond to the
single client on that old tape that I want, using the SAME client ID as
what's on the tape.

Then "scanner -i" on that tape again, and limit it only to the ssid or
client that I want. And since my current NW server has a client with a
client ID that matches the client ID, I'd end up with a dummy client that
I could do a redirected recover from.

I know I've done this in the past, I just don't remember the "could not
create saveset for ssid" messages (it was a really long time ago that I
last did this).

Is this normal? My method should work, right, for me to do a redirected
recover?

Thanks

'scanner -m' should tell you exactly what it excpects
- block size for the tape
- the pool (you might need to create)
- hostname
- client ID

Your message seems to be incomplete. This is what I get with NW 9.2.1:
.....
115743:scanner: Unable to create save set for SSID '24114': Unable to determine client ID for client 'ultra'
8814:scanner: ssid 24115: host `ultra' must be a valid host name
.....

Well - this is a small backup on an 'optical' media which I created 22 years ago on a NW 4.2 backup server.
At that time there NW did not use client IDs yet ;-)
But of course NW will assign one if you create the client.

To (re-)create a (fake) client you just must add an appropriate entry in the hosts table.

Then you can even run "scanner -i' and check the result later:

Z:\>nsrck ultra
113429:nsrck: checking index for client 'ultra'31713:nsrck: E:\nsr\index\ultra contains 1042 records occupying 163 KB
