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" --- Em sex, 4/2/11, ANDREW LEMIN <a_lemin@hotmail.com> escreveu: De: ANDREW LEMIN <a_lemin@hotmail.com> Assunto: ontape -t STDIO and stderr [22701] Para: ids@iiug.org Data: Sexta-feira, 4 de Fevereiro de 2011, 15:25 Hello, I am having trouble scripting ontape.

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 John F.
