Hi, I've been trying to enable hardware compression on a HP C6364A/C1537A SCSI tape drive. Searching google and this list, I've found questions but not any answers. I've found 'mt compression on' or 'mt defcompression' is supposed to do this but I don't see it working. I'm using a DDS1 tape capable of 2G uncompressed, 4G compressed for testing. I try turning it off with 'mt compression off' and it runs out of tape as expected. I try the above commands and I still run out of tape. The data I'm using as an experiment is 2.28G in total. Any ideas? Is there a simple way to verify the compression is turned on? The response to 'mt status' is always the same: [root@hbwpe2 prod]# mt status SCSI 2 tape drive: File number=0, block number=0, partition=0. Tape block size 0 bytes. Density code 0x13 (DDS (61000 bpi)). Soft error count since last status=0 General status bits on (41010000): BOT ONLINE IM_REP_EN Thanks in advance for any ideas!
