I've gone back through the list about the slow LTO issues. I haven't found anything that works in this case.
TSM V4.2.1.9 W2K SP2 3584 Library at latest firmware LTO drives at 18N2 firmware latest on devdrvr Netfinity xSeries 350 LTO Device driver is 4.0.2.4 - tried 4.0.2.1 and previous versions of 4.0.1.x RSM disabled. Possible issues: Drives and library are connected using the motherboard SCSI 7899 Ultra 160 chips - one per channel - no internal devices connected. I know about the Microsoft vs Adaptec supplied driver but can't determine if it applies to this chipset. Cable length to get to the library is long but already installed under the floor - at least the 12 meter limit and maybe a bit longer (I'm trying to find out) These drives write at about 4G/hour even on 4 GB files. The device drivers don't stay loaded after a reboot but have to be updated by hand. Does anyone have any suggestions to speed these drives up? Thanks, Bill Smoldt STORServer, Inc.
