Hello:
I'm running an HP DAT 4mm Autochanger here and since going to 2.2.17 and 2.2.18 I'm seeing failures when it attempts to unload the tape and load a new one while backing up using BRU PE...utilizing the mt or mtx commands as follows:
mt -f $DEV rewoffl 2>&1 >/dev/null
OR
/usr/local/bin/mtx -f /dev/sg1 eject 2>&1 >/dev/null
If I use the MTX command set to "manually" change the tapes all is well....any thoughts on the cause or a fix...I don't think the hardware is broken due to the fact it runs fine "manually" by doing the mtx -f /dev/sg1 next commnand to load the next tape
Pertinent info below:
