[Q] SUN L9 (DLT8000) run very slowwwww ....

2007-12-24 20:47:00

We have SUN 280R (Solaris 8) with external SUN L9 tape library
(DLT8000). i found the tape driver run very slow. Our nightly ORACLE
backup (use "tar" utility, few files, but big size) total 20GB. It take
almost 4 hours to finish. Base on DLT8000 document, the speed should
6Mb/12Mb per second. That mean even on 6Mb/sec, a hour DLT8000 can backup
20GB. Can anyone tell me what wrong it is?

Thanks.
