Question Help with iostat ...

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.

FPA(4)							   BSD Kernel Interfaces Manual 						    FPA(4)

NAME
fpa, fea -- device drivers for DEC FDDI controllers SYNOPSIS
device fpa device fea FreeBSD only: device fddi DESCRIPTION
The fpa and fea device drivers provide support for the DEC DEFPA PCI FDDI Controller and the DEC DEFEA EISA FDDI Controller, respectively. All variants of either controller are supported including the DAS and SAS configurations. DIAGNOSTICS
fea%d: error: desired IRQ of %d does not match device's actual IRQ (%d) The device probe detected that the DEFEA board is configured for a different interrupt than the one specified in the kernel configuration file. fea%d: error: memory not enabled! ECU reconfiguration required The device probe found that no device memory had been configured on the DEFEA. Although the DEFEA can be configured with no device memory, this driver requires a minimum of 1K device memory to be set up. The ECU (EISA Configuration Utility) will need to be run to change the settings. CAVEATS
Normally, the device driver will not enable the reception of SMT frames. However if the IFF_LINK1 flag is set, the device driver will enable the reception of SMT frames and pass them up to the Berkeley Packet Filter for processing. SEE ALSO
