The command isn't one hexadecimal number, but rather individual hexadecimal
numbers for each byte in the CDB.

You also need to specify either "-" to direct the output to stdout, or
specify the output format.

For example:

# camcontrol cmd da16 -v -c "12 1 83 0 ff 0" -i 0xff - |hd
00000000  00 83 00 48 01 03 00 08  50 00 c5 00 10 3f 70 23  |...H....P....?p#|
00000010  61 93 00 08 50 00 c5 00  10 3f 70 21 61 94 00 04  |a...P....?p!a...|
00000020  00 00 00 01 61 a3 00 08  50 00 c5 00 10 3f 70 20  |....a...P....?p |
00000030  03 28 00 18 6e 61 61 2e  35 30 30 30 43 35 30 30  |.(..naa.5000C500|
00000040  31 30 33 46 37 30 32 30  00 00 00 00 00 00 00 00  |103F7020........|

Or, if you want nicer output, try installing the sg3_utils package.  It
will fully decode page 0x83:
