You should install the edac-utils package (and dependency libedac1 if you're not using apt or the like). To check for errors, just run edac-util (see the man page for more information) However, on our R710 (running RHEL 5.4, not Debian Lenny, but makes no difference in this case) there are no EDAC drivers that support the system's memory controllers. If you are *really really* adventurous, you could try pulling Mauro Carvalho Chehab's patches to the Linux kernel - just two weeks ago! but with updates from this past weekend (see http://archive.netbsd.se/?ml=linux-kernel&a=2009-09&t=11598929 for more details) - that add an i7core_edac driver for the Nehalem chipsets and back-porting it into whatever kernel Debian Lenny uses. So you will probably need to wait a few weeks or even months for this to stabilize and get accepted into the mainstream Linux kernel, and then a few months more to percolate out into the various distros - and while I'm no expert on Debian release schedules, I'd bet this feature never makes it into Lenny, but maybe an update to the 6.0 "Squeeze" release. Unfortunately that is the price we pay for running OS!=Windows on the latest greatest hardware... It would be nice though (for us RHEL people, more than for you Debian folks) if some of the developers at Dell could spend a bit of time testing out Mauro's driver, pushing for its acceptance into the Linux mainstream kernel, and maybe even back-porting the patches into the Dell-supported (RHEL 5, SLES 11) distro kernels so that we don't all have to become git/kernel hackers or wait six months to get the benefit of Mauro's work. @alex -- mailto:[email protected] _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
