Hello, I'm having a terrible time trying to clone volumes from my VTL to 
physical tape. I created a script to do the following:

mminfo -m -q 'savetime>=yesterday 10:00:00,savetime<=01:00:00 today' > 
13hr_report

then:
awk '{print $1}' 14hr_report | grep VT* > vtlist8day 
 - which pulls out any barcodes with VT* written in the last 13hrs so as to 
only clone VT### tapes and not all tapes

then:
nsrclone -v -s cinatl01 -b vtlclone8day -f vtlist8day
- this clones all the VT## volumes from vtlist8day

The problem is that nsrclone will only clone 1 volume at a time, therefore, all 
I/O is put on one drive, reading from 1 tape and writing to 1 tape

I've been reading up on cloning from SSIDs to get around this issue but cannot 
find anything that really helps. 

I would like to clone at least 3 or 4 VT## volumes at once to physical tape. 
Does anyone have recommendations or how to pull SSIDs writtent to VT## volumes 
written in the last 13hrs and then clone those volumes in parallel?

Thank you.

That pearl script sounds like something I could use
