Dump issues after upgrading from Redhat 8 to CentOS 5.3

I recently upgraded one of our critical servers from Redhat Linux 8 to CentOS 5.2.  After I did that the backup script started having problems.  The tape drive is a Dell PowerVault 100T DDS-4 (using 150 meters, 20/40GB tapes)

Here is a portion of that backup script:

/sbin/dump 0uf /dev/st0n /home
/sbin/dump 0uf /dev/st0 /data

Here is the log from that backup after the upgrade:

Try running the actual dump command manually from your terminal. Trying to open /dev/tty could mean it requires user interaction. Once you figure out what it is asking you can adjust your scripts dump switches.

I changed the dump device from /dev/st0n and /dev/st0 to /dev/nst0 and /dev/st0.  In my original script I had the "n" for no-rewind after the "st0" instead of before.  That seems to make all of the difference.

Thanks,
Matt
