Hi!!! I've got an HP SURESTORE DAT 40 on my SUSE LINUX ENTERPRISE SERVER 8 BOX SP3. The tapes I use are marked 20/40GBYTE. But I can only make backup up to 20G, whereas on my ALPHA server with tru64 unix, I can save up to near 40 Gbytes using the dev file "/dev/rmt0h" (for tru64 V 4F) or "/dev/tape/tape0_d1" (for tru64 V 5.1B). I try to enable compression using the command "mt -f /dev/st0 datcompression 10", this command achieved succefully but nothing. I try to use the /dev/st0m or /dev/st0a, but these devices files seem not to be associated to physical device. So how can I perform backup with hardware compression? Please help
You may have to use stinit from the mt_st rpm. With my LTO-1 drive I have had to use stinit to even get it to work until SuSE 10.0. That is I am no longer calling stinit prior to using my drive, but I had to for the last couple of years with various SUSE kernels. Unfortunately the 10.0 kernel does not properly detect end of tape. So I'm running with a 2.6.14 vanilla kernel on my tape server. (It works perfect from what I can tell and still no stinit.) HTH Greg -- Greg Freemyer The Norcross Group Forensics for the 21st Century
