How to acticate hardware compression using tar command

I'm using a single LTO SCSI-Drive HP 1840 at a Linux-PC (Suse 10 SP1). Sometimes it's required to operate with tar command in place of the comfortable DPX software. How could I activate the built-in hardware compression of the drive in this case? Michael

Hi,

Hardware compression is by default enabled in the drive and we don't have to enable it.

Re: How to acticate hardware compression using tar command

Hello - Raj,

I posed the question imprecisely, sorry. How could I switch the built-in hardware compression on or off? But meanwhile I read, the drive is able to realize if it would be better to compress or not. Can you affirm?

By the way, do you know the meaning or differences between the device files st0, st0a, st0l, st0m in /dev? I only know the difference to the no-rewind device files nst0, nst0a, nst0l, nst0m.

Best regards - Michael
