This
link seems to suggest that your messages are harmless.
The sequence of commands that you ran seems to nearly be in reverse order. But the reconfiguration reboot should have done it. I don't know why the tape drive is not being seen, maybe it's busted. An empty /dev/rmt is normal for a system without tape drives.

Hi all,
Sometimes, when I reboot my AIX server, my tape drive /dev/rmt# assignments change. This creates some tedious TSM work prior to and after a reboot of the server.
Is there a way to ensure that the /dev/rmt# assignments come up the same every time?
Thanks (5 Replies)

tcopy(1) User Commands tcopy(1)
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
