Have a look at the 'fcstat' command recently introduced into AIX. This
will output an unpleasant bunch of data, but some nice scripting can
isolate the FC SCSI Traffic Input Bytes and Output Bytes lines for the
desired HBA, even if the HBA

And on this one . . .
Have you tried nmone with ^ ?
And what is the fcstat command in? AIX? Not in my man pages and find
doesn't show fcstat.

I wrote a small script to collect the snmp data from the Brocade fibre
switches and put the data into Servergraph.
Next I created a report to graph the data and in that way we could see
historical data throughput and identified more than once a faulty tape
drive!
You definitely want to monitor
An interesting source of tape drive performance data is the TSM server
itself, in the SUMMARY table.
Extract it with SELECT into a comma-delimited or tab-delimited file, and
then read it in to any popular statistical program like SPSS or SAS. You
have to match up the records for processes such as
