vivekbhatia,

In this question you are looking for some Kernel Instrumentation information, there is a tool that can help on this task which is the Kitrace tool, the tool is not easy to use and the output is really complicated, it would tell what the process are doing at a specific moment in time.

Regards,

Jaime.

If you have HP-UX KWDB kernel debugger, you could check out the stack trace of the processes to find out this info.

Can you tell us what exactly is the problem you are facing? May be there are other alternatives...

Actully getting lot of error messages in Syslog.log
So i setup the timeout value for the disk(using pvchange -t ) so now i am not facing those errors but i wanted to know that which are those processes which were waiting to write on that disk?

Thanks
