I just changed my longtime Amanda server from BSDI to FBSD 4.4-Stable and
I'm not sure if I'm using the correct tape device.

Here's what dmesg shows:
sa0 at ahc0 bus 0 target 6 lun 0
sa0: <SEAGATE DAT    06240-XXX 8071> Removable Sequential Access SCSI-3 device 
sa0: 80.000MB/s transfers (40.000MHz, offset 32, 16bit)

So for the non-rewinding tape device I put in /dev/nsa0, which seems to
make sense after reading the mt and sa man pages (I know, I shouldn't be
RTFM'ing before hand, but oh well ;).

So, when I try to access the drive by running amflush I get this kernel
message:

(sa0:ahc0:0:6:0): tape is now frozen- use an OFFLINE, REWIND or MTEOM
command to clear this state.

so I run 'mt -f /dev/nsa0 rewind' and things appear to be okay, but I
still get that error.  Also tried this:

# dump 0f /dev/nsa0 /etc
  DUMP: Date of this level 0 dump: Mon Apr  1 17:27:47 2002
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /etc to /dev/nsa0
  DUMP: bad sblock magic number
  DUMP: The ENTIRE dump is aborted.

Any suggestions?

Thanks!
