Hi,
Is there any processes hanging related to the tape drive (tar,cpio,dd etc.) ?

Hi,

look for processes relating to the tape drive (backup like tar, cpio ...) or check
with "mt -f stat"

# mt -f /dev/st0 stat
/dev/st0: Device or resource busy

and I not use tar , cpio , dd , I am installing the backup software to it ( arcserve ) , then it hanged.

thx

Hi,

Could you do a fuser -u /dev/st0,
And check the pid using ps -eaf?
