Proactive polling and continue Tresspassing con EMC array

ASO FINANCE — Mon, 18 Feb 2008 13:13:58 GMT

Hello gurus,

I've got a lot of continue Tresspassing errors from two servers HPUX 11.23 (rx2660) with ServiceGuard 11.17 and an EMC array and I must put Proactive Polling

from /dev/rdsk/c10t0d3 I need to set Proactive Polling off on some LUNS where I have
errors. But, If I try to set Proactive Polling off I have this:

# pvchange -p n /dev/dsk/c11t0d3

wich gave me this:

# vgcfgbackup: IO error on Physical Volume device "/dev/rdsk/c10t0d3".
I/O error

and :

# pvdisplay -v /dev/dsk/c10t0d3|more
--- Physical volumes ---
PV Name /dev/dsk/c10t0d3
PV Nme /dev/dsk/c11t0d3 Alternate Link
VG Name /dev/vg07
PV Status available
Allocatable yes
VGDA 2
Cur LV 14
PE Size (Mbytes) 32
Total PE 3999
Free PE 500
Allocated PE 3499
Stale PE 0
IO Timeout (Seconds) 180
Autoswitch On
Proactive Polling Off

What should I do now?

Thanks in advance, guys.

Hi,
It looks like vgcfgbackup is unable to read from ""/dev/rdsk/c10t0d3" this disk.
Try reading 256MB of data from 8K offset from that PV.
use the following command.

dd if=/dev/rdsk/c10t0d3 of=/dev/null bs=1024 count=256

If the command passes with out any error, then we need worry :(

If the above commands fails then the disk has bad sectors.
