Most tape drivers these days will ignore your request to set the drive to the wrong density when reading. Instead, they sense the tape's density and will silently change the density to whatever is correct. But if you work on an old 9-track tape drive you may find that the driver has no easy way to sense density and the tape will seem to be unreadable.
Many people will dump several filesystems on the same tape by specifying the no rewind bit. After the first dump, the tape is left positioned ready to write a second dump. If you wanted to restore a file from that second dump, you would first need to "mt fsf" to get there. You better specify the no rewind when you do. Then for the restore, you could use an auto-rewind special file. I almost always will use the no-rewind option. I can always do an explicit rewind when I want.

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)
