Operating Systems AIX help with tape drive on aix 5.1
# 15  
Old 01-13-2004
I'm still not clear on what type a drive this is. A few drives can read more formats than they can write. For example a DDS 3 drive can read DDS2 tapes and DDS tapes. But the DDS 3 drive that we have cannot write on DDS 2 tapes. So it might be that you the wrong tapes for the drive to write on.

But the most probable answer is that you have a broken tape drive. The drive request a cleaning when a write operation fails that it expected to work. That often fixes the problem when writes fail. But not always.

NAME
tcopy - copy a magnetic tape SYNOPSIS
tcopy source [destination] DESCRIPTION
The tcopy utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the contents of a tape is that there are two tape marks at the end. When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files. If a des- tination is specified, tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro- duces the same output as it does when only scanning a tape. The tcopy utility requires the use of Berkeley-compatible device names. For example, example% tcopy /dev/rmt/1b /dev/rmt/2b ATTRIBUTES
