Hello guys!

I have some servers HPUX 11 and Hitachi Storage in which I would like to ask you somethings:

Is it possible to monitor the things below from command line or some script?

- Throughput of SAN;
- Bytes passed through by canal;
- Tax of occupation by canal SCSI;
- Tax of occupation by canal Fiber Channel.

I don't have any software for do it.

Please, could someone give me a help?

Thanks,
clefeitosa

Shalom,

I'll add something similar with more capabilities not directly related to the question.

Note that these tools will help you identify the problem. I've been seeing more frequently that I/O related issues on the OS are related to shall we say strange and untested configurations on the disk array.

A recent agregious example was fixed by an EMC tech after an enormous amount of resources were expended to find the problem, looking at the application, OS and network side of the situation.
