    Does anyone know a way, (other than using SystemTap + iostat-scsi.stp script), to get Tape Drive performance statistics?

    Red Hat Enterprise Linux Server release 5.7 (Tikanga)
    Kernel 2.6.18-274.12.1.el5 on an x86_64

    Attached Tape Devices:
    Number model SN HBA SCSI FO Path
    0 ULT3580-HH5 1068028623 qla2xxx 1:0:0:0 NA
    1 ULT3580-HH5 1068030139 qla2xxx 2:0:0:0 NA

    I want to get throughput information out of these tape drives.

    In AIX, you can just do iostat -p and get that information (assuming atape driver is installed). There doesn't seem to be anything like that for Linux.

    Anyone know of anything?

    (I don't use SystemTap + iostat-scsi.stp script because it's not meant for production. It's known to cause kernel dumps and crash systems.)
