When the VXA-1 SCSI tape drive is set to "/dev/nst0" (as default) in e-smith v.4.1.2, it causes input/out error when dump data to tape using flexbackup. When it is change "/dev/st0", writing data to tape is OK but the section of / (file number 1) seems overwritten by /boot (file number 2). I suspect that after the dump of '/' to tape, the "/dev/st0" is rewind to BOT before start next dump of '/boot' as the Block number is always start at "0". Does anyone know how to fix it? Note: I have tried to set the tape device to different name but only found /dev/st0 work without I/O error during dump. Reason unknown! Thanks in advance
