Hi to all, RHEL 5.7 IDS 11.50.FC7 Before I do my nightly system backup, I do my ontape commands, and block the server. After the backup, I uublock it and all is OK. Without getting into useless details, sometimes the backup hangs needing new media and waits. When users come in the next morning, the server is blocked and I need to unblock it. I want to create a cron job that will run long after the backup should be complete to unblock the server if it is blocked. My questions are: Is there a simple way to test if the server is blocked or unblocked? "onstat -;echo $?" returns 5 (online mode) in both cases. I could use "onstat - | grep Blocked". Or do I even care? If the server is unblocked and I run "onmode -c unblock", I get a message that the server is already unblocked. Does unblocking an unblocked server hurt anything? David

Hi, you can always check with onstat -p | head -3 | grep Blocked But why do you block the server during backup with ontape ? You can do a backup unblocked ...

Yes, I could do the backup without blocking, but with blocking (and= =20 ontape) I get two IDS backups. Its the paranoid admin in me. Your= =20 onstat.... is functionally the same as what I thought of. I was looki= ng=20 to see if there was an standard way to see if the server is=20 blocked/unblocked.

if you are using ontape, then you could send the backup to STDOUT and pipe it to two output devices at the same time.
