Why does pkgadd fail with this error message?

    "UX:pkgadd: ERROR: device </dev/rmt/0m> is not listed in device table."


This error message comes up when the device specified by pkgadd is not in
/etc/device.tab.

        # pkgadd -d /dev/rmt/0m
        UX:pkgadd: ERROR: device </dev/rmt/0m> is not listed in device table.


To allow pkgadd to use the device you must first add the device using the putdev
command.

        # putdev -a tape0 cdevice=/dev/rmt/0m volume="Dat tape"

Note: It is necessary to define the volume attribute in order for pkgadd to
recognize this device.


After the device has been added with putdev the pkgadd command will work.

        # pkgadd -d /dev/rmt/0m

        Insert a Dat tape into tape0.
        Type [go] when ready,
          or [q] to quit: (default: go) 
        ....
