vxfsd usage ?

[MikeL_4]

We have the following server configuration that is used as a database server running six (6) Oracle databases.
............ Model: 9000/800/rp7420
............ OS Level: B.11.11
............ OS Mode: 64 bit
............ CPU Count: 8
............ CPU Speed: 1000
............ Physical Memory: 32733 MB
............ SWAP Allocated: 47104 Mb
............ Memory Page Size: 4096

We are trying to isolate a speratic CPU utilization issue with one of the databases and noticed that the vxfsd process is averaging itself about 25% CPU%. I checked this process on all of our other servers and at most it is at 5% CPU%.

1 ? 49 root 152 20 16000K 16000K run 3903:29 25.28 25.24 vxfsd

What is normal for this process ?

Shalom,

This is indicative of an i/o problem.

You might wish to run http://www.hpux.ws/system.perf.sh
Performance scripts and take a look at the disk report and see which one is busy.

A lot of these problems are caused by insufficient patching. Going to the latest stable OS patch, December 2006 or June 2006 might alleviate this issue.

It can also be triggered by doing OS striping across multiple LUNs presented by an EMC or EVA disk array.

thanks, we did find some netbackup processes that were running.
