What is vxfsd and do I need it with only HFS lvols.

I have a H50 with old drives and controllers. I just upgraded to 11.00, I have LVM and mirroring and all of my LVOL's are HFS. Lately I have been getting the following msg's

Mar 26 11:37:02 cancun vmunix: dev 1c022000 got invalid b_resid 0 b_bcount 8192,
error = 0x7c
Mar 26 11:41:30 cancun vmunix: LVM: vg[2]: pvnum=4 (dev_t=0x1c022000) is POWERFA
ILED
Mar 26 11:42:23 cancun vmunix: LVM: PV 4 has been returned to vg[2].

HP engineers came out and said there are no problems they are false errors. The last time I had something like this I had just installed the Diagnostic package and had to turn off resmon, but I do not see this in 11.00. The only thing I can see is the vxfsd running and having a lot of cpu time and load heavy. I removed the online diagnostic tools this morning hopping that one of the tools were checking the old drives like before (1&2Gig drives) but I just recieved the errors again.

Two things here .. (both not necessarily related to each other )..
1) The POWERFAILED error message , as mentioned by HP engineers are "non-destructive" error messages and usually misleading. I have occasionally seen this on my 11.00 L-Class and what I did was apply the latest LVM cumulative patch (PHCO_24437) and the message went away.
2) The vxfsd daemon is something you simply cannot disable of turn off. Again I'm afraid patching up the system with the latest JFS performance patch should solve your problem of vxfsd using too much of CPU resources. The patch you need is PHKL_18543.

I think your system is swapping too much and you are running short of memory. Just have a look at swapinfo -tm . I don't know whether you are having glance or not. iF IT IS THERE look through glance about the available memory.
