Here's what happens: at boot time, the tape drive is detected as device ast0:
/kernel: ast0: TAPE <Seagate STT20000A> at ata1-slave PIO4
When I insert a brand-new 4/8GB tape and run 'mt -f /dev/ast0 status' as root I get the following output:
Mode Density Blocksize bpi Compression Current: 0x01:X3.22-1983 512 bytes 800 none ---------available modes--------- 0: default variable 0 none 1: default variable 0 none 2: default variable 0 none 3: default variable 0 none --------------------------------- File Number: 0 Record Number: 0 Residual Count 0
but I get the following message in /var/log/messages:
/kernel: ast0: TEST_UNIT_READY - HARDWARE ERROR asc=0xf0 ascq=0x36 error=0x00
Similarly, if I run 'mt -f /dev/ast0 rewind', I get no output to the terminal but the following in the logs:
/kernel: ast0: TEST_UNIT_READY - HARDWARE ERROR asc=0xf0 ascq=0x36 error=0x00 /kernel: ast0: REZERO - HARDWARE ERROR asc=0xf0 ascq=0x36 error=0x00
After either of these commands, if I run 'mt -f /dev/ast0 errstat' the terminal displays:
mt: /dev/ast0: Inappropriate ioctl for device
So, does this suggest the drive is fried, or am I doing something wrong? Google search shows that 'inappropriate' message popping up occasionally for all manner of devices on both Linux and BSD, but usually the hits are in the form of mailing list posts with few, if any, responses, and nothing that seems relevant to my situation. Any ideas?
Thanks in advance,
-Brandon
