And another thing..... It isn't a problem with REXEC or REXECD.
Instead of executing each command via REXEC to Linux, I created a script which had all the commands in it. So, REXEC only executed the script. But what happened was.... The tar was being executed. Long before the tar completed, bash started executing the remainder of the commands in the script. However tar was still running (and keeping the tape drive in use). This is similar to tar being executed asynchronously. However, when I run the script interactively, from Putty (actually Kitty), the command runs like it is suppose to. Only when the tar completes does the next command start to executed. So, it seems, at this point, that tar knows when it is being executed remotely and returns control early (and continues to execute). However, executing the script using VM's REXEC, didn't produce the asynchronous behavior. So, REXEC from VSE using the CSI 1.5E stack seems to be telling tar something that REXEC from VM (z/VM 5.2) isn't. Time for a beer.

You shout be able to find out which process is using it via "fuser /dev/ntibmX". with kind regards Carsten Otte IBM Linux Technology Center / Boeblingen lab -- omnis enim res, quae dando non deficit, dum habetur et non datur, nondum habetur, quomodo habenda est ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/ ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
