/dev/rmt/c0t0d0BEST

I using the tar -cvf /dev/rmt/c0t0d0BEST /tmp/1.log,
I was use the best density and compression options. But how do I know the /tmp/1.log was compressed in the tape. I was seen the tar -tvf /dev/rmt/c0t0d0BEST, the /tmp/1.log size same as before. How do check if the tape data was compressed?

There is a utility called ddsinfo that might help provided you are using a dds tape drive.

The version is available for 10.20 but it might work on 11.x. You would have to give it a try.

My tape library is SuperDLT .
Does this tool support such as device?

Goto /dev/rmt.

Do ls -il. The device files used are same for best density files.

lssf /dev/rmt/c0t0d0BEST will give you the details abt. that file.
