In a Ubuntu system I have an LSI card with a 53C1030 controller and I'm getting write speeds to LTO4 tape at only 4MiBps. The drive should be capable of 120MBps.
I have found a copy of lsiutil
and attempted to enable write caching but I don't have the proper options under the RAID menu.
Is there some other form of configuration I need to do? Or is there a compatibility or hardware problem?
Here is some information on the card:
$ lspci | grep SCSI
