ontape -t STDIO and stderr
Andrew Lemin found that ontape -s -L 0 -t STDIO sent no error messages to stderr, and that ontape only returned exit codes 0 or 1. Cesar Inacio Martins pointed to the -d and -v options on 11.50+, and John Miller III confirmed that -v is needed to write informational messages to standard error with STDIO. Andrew thanked them. Solved.

Hello,
I am having trouble scripting ontape.
It appears that 'stderr' messages are printed on the 'stdout' stream and not
the 'stderr' stream as normal.
When using 'ontape -s -L 0 -t /backup/backup.bak' I can get around this by
analysing the 'stdout' stream in my script when the exit code '$?' is non-zero.
HOWEVER when using 'ontape -s -L 0 -t STDIO' the data is passed out on the
'stdout' stream, and all error messages are muted so there are no error
messages when using STDIO!
Is this right?
Also I am surprised that it only has 0 or 1 as exit codes.
Thanks in advance for your help.
If you are using at least v11.50 , check for the parameters "-d" and "-v"

In order to display messages to stderr, when using the STDIO option you
must
supply the "-v" option. Below is the line from ontape's usage message
ontape --
..... top truncated for brevity........
-v Write informational message to standard error during a backup to
standard
output or restore from standard input
