All,

I am attempting to help tune a Sun for better performance (mainly for SAS 9.1), and have found indicators pointing to poor I/O utilization. I have run iostat -cx, and found one device in particular where the %w is in the 90's during processing. I have a feeling that this is where the SAS temporary file are held, but I am not sure how to check to make sure.

So, how can I see what directories are on this device (oh, and I do not have root access).

Can anyone offer any tips/tricks for tuning in this situation?

Thank you very much for any help.
