SUMMARY: flar to tape : write: not modulo 2 device granularity error

Hi All,

OK I got zero replies but for completeness my solution was to use the 
following syntax:

#flarcreate -n "some archive name" -t /dev/rmt/0c

ie /dev/rmt/0c not /dev/rmt/0

Looks like you need to completely specific the tape device, I guess 0h 
etc work too.

Cheers,

Rob
