Hi We have a 3584 with 3 drives; 2 are SCSI attached through a San Data Gateway R03, and one drive is direct FC attached to a switch. We're using this library with a IBM P-Series 610 with one FC adap

Hi Daniel! The SAN Data Gateway uses High Voltage Differential SCSI interfaces by default. If your are using the default SCSI interfaces, your drives will probably be also HVD drives. They perform co

Hi Erick, I saw your last mail, and I'm wondering how you can check if you're using HVD or LVD interfaces. Is it related to the SDG's hardware, or just a question of microcode ? Could you please give

Hi Arnoud! Let me first say this: I'm not a SCSI expert! The difference between LVD and HVD SCSI is hardware related. LVD, which stands for Low Voltage Differential, is also called Ultra 2 or Fast-40

I found a nice website explaining the different types of SCSI, it's at: http://www.cablingdirectory.com/techinfo/scsiinfo/scsi.htm Check if you can find a small symbol next to the connector on the SC

Eric, That with "drive compression" turned on - device class format = drive. That number comes from "topas" which is measuring OS activity and reports physical bytes, not TSM's logical bytes. Thanks.

David, Check the FILE/TTY Readch and Writech numbers while only one drive is active on the system. Our system is small enough that we get that one-drive-active condition. Thanks. Tab David Longo <Dav
