iostat -cxn 5 is what I use to monitor the tape devices.

Subject: monitoring performance from tape? [Virus checked]

Hi,

what is the way to monitor the performance from a scsi-adapter and the
tape
drive.
I can observe disks, network, cpu performance with some tools (topas,
vmstat, iostat, ....), but I cannot see the really datarate from a tape.
Reason is: We chnage 3590 type B to 3590 drives type E. The type E is
faster, but what is the way to monitor this?

Best regards,
Frank
