HP Ultrium 448 SAS - enable compression

we have HP Ultrium 448 SAS tape drive installed on HP 370G5 server. 

 

I want to enable hardware compression for this tape. 

 

please find below other details:

 

[root@proddb Backups]# mt -v

mt-st v. 0.8

 

when i execute  "mt -f /dev/st0 compression 1" it does not display anything and cursor moves to next prompt.

 

second how to check that compression is enabled or not.

 

Kind regards,

Asim
