>Description:
The OnStream SC50 tape drive doesn't work with mt(1), which prints the
following error and exits for all commands:
mt: /dev/nrsa0: Invalid argument
And the following dmesg is logged simultaneously:
(sa0:ahc0:0:6:0): REWIND. CDB: 1 0 0 0 0 0
(sa0:ahc0:0:6:0): ILLEGAL REQUEST info?:b6ca6 asc:24,0
(sa0:ahc0:0:6:0): Invalid field in CDB
After some experiment, it seems that the drive only accepts REWIND
command only when the `immediate' flag is set in CDB, i.e. `camcontrol
cmd -c 1 1 0 0 0 0 -n sa' works as expected.
>How-To-Repeat:
Install the OnStream SC50 tape drive and issue `mt status'.
>Fix:
No fix or workaround known.
