SAN disk very busy in HPUX server

Dear HPUX gurus,
would like to seek your advice. from glance, the server disk util is 100%, and memory is 99%. the swap space is not high. can the processing on the disk cause the memory to use up a lot. how to investigate further if we have this kind of problem. Hope to hear from you. Many thanks in advance

Check the process from top command,which process are using high memory and intimate to them and resolve the issue.

Can you check from glance which filesystem and which specific disk util is high.

You may also get the specific LV from it.

what does swapinfo -atm shows?

Open a session and keep monitoring the resource utilisation using glance or command line utilities like swapinfo, vmstat till you encounter the issue. Also monitor other resources(CPU, disk, etc) utilisations. Either one could be the issue.

If possible check which are the unwanted process are running and which are taking more memory.
If those process are not reqired or old porecess try to kill those process.

If Oracle or SAP is working then check the oracle dead oracle process.
