Does this seem to be an nsrclone issue specifically or drive/media
issue?

All,

I had jumped on this thread (sorry) with an issue with my nsrclones
hanging
when a SCSI write error was encountered.   I did find the source of my
write errors to be one drive.   Still, it would seem nsrclone can hang
indefinitely reading the source tape if the tape tape has a SCSI write
error.

Legato has added me (and this behavior) to LGTpa60542. No hotfix for
7.1.1
yet..may have to wait for next release.
