Re: Data From Tape -- MIDRANGE-L

I didn't make myself clear.  When you do a dsptap it shows the new library only.

I am not an expert but there are some approaches I might take.

1. GO RESTORE & check the on-line documentation.

I had a case of one member within a file had got accidentally deleted & I did 
not know when it happened, so I was digging into past backups to locate one 
that had that file, then I only wanted to restore that one member that was 
not on-line & not replace the ones that had changed since those backups - 
first thing I did was another backup in case I mucked up the restore.  I did 
muck up the restore, but not fatally.

RESTORE is much more complicated than SAVE, because in SAVE you are simply 
backing up everything & making relatively simple decisions about what you 
will permit to run at the same time as the SAVE that might interfere with the 
process, and how you will verify that you saved everything that you intended 
to save, and generally going through the same process daily so you have 
memorized the right options, and may even have written some simple programs 
to do some of the options for you.

RESTORE involves a jigsaw puzzle - which stuff do we want to restore out of 
the whole - do we want to replace what is on-line or do we only want to 
restore what is missing & how do we handle links that cross libraries, so as 
to restore the physical before the logicals & security, and since we only 
need to do this once in a blue moon there is a learning curve just getting up 
to speed on how to do it.

2. GO TAPE for menu of various options to dump stuff, display stuff, extract 
stuff from tape media, other than the standard restore options.

3. Call my hardware provider & ask about pricing for a temporary use of their 
hot site.
We got our 400 from a local outfit that has old copies of old 400 boxes.  We 
found out about this when discussing compatibility with old off-line media in 
selecting upgrade paths.  If you have similar hardware support, you can take 
the media to one of their systems & restore it ... it won't work there due to 
software license keys, but we have done SAVE-21 with selective 
RESTORE-excluding operating system when migrating to a new box ... now with 
your restore on that other box, you can do a single save or GO BACKUP of the 
individual library you want to extract.
