I've cc'ed dm-devel may be some DM guru could give his opinion on this. Next time, I'll use a sg_dd instead of dd, to bypass any cache effect (by the way, does VFS cache anything when addressing /dev/X devices ?) > I'd like to know the i/o failure if so. > > > > /dev/sd devices timers are set to default udev value, 60 seconds. > > > > Something that may help is the firmware rev of the HBA's : 2.50A8 > > (Z2F2.50A8), sli-2 > > > I'm guessing this firmware is a bit old... > I see the latest for this adapter should be F/W version 2.72A2 or later > See Table 9 for 403621-B21 (the LPe1105-HP mez) at > http://docs.hp.com/en/5900-0486_e2/ar01s05.html?jumpid=reg_R1002_USEN > > Here's a link to 2.80a4 (8/14/2009): > http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&swItem=co-74079-1&jumpid=reg_R1002_USEN > > However, I'm not sure that's the root of the issue. > > Checking the driver rev - the latest for rhel5.3 is 8.2.0.39 available at: > http://www.emulex.com/downloads/emulex/cnas-and-hbas/drivers/linux.html > > It wouldn't surprise me if the 8.2.0.66 version works as well.

As our DWDM ring switch is on the less optimal path, there will be a switch back to nominal soon. I'll activate this log level on the HBA's and check the firmware versions you gave me . Hopefully, we will be able to provide you something deeper to investigate.
