Hi, Juha. My first suggestion would be to see if you have the proper IBM tape (3590) device driver modules either built directly into the kernel or loaded at runtime. An lsmod command should tell you this.
Good luck. Juha Vuori wrote:
We run SLES10 SP1s under VM, and make data backups to 3592 tape machine directly from linuxes. I understand that there should be a compression feature inside this tape system. According to Device Drivers, Features, and Commands - SC33-8289-04, it could be activated in tape_3590 driver with # mt -f /dev/rtibm0 compression 1 but "mt" in this distribution does not support "compression" command. Compressing with tar -czf ... works fine, but gzip eats lots of cpu. So I would be happy to get advice on this, or references to good books...
