Hardware Raid LSI Megaraid Not Working Since CentOS 6.6

Happy new year !

We have a SuperMicro server with a LSI MegaRAID 9260-4i controller.

Since CentOS 6.6 update (kernel 2.6.32-504), the controller doesn’t initialize at boot. Reverting to kernel 2.6.32-431 allows server to boot fine.

The server can’t boot due to a bug in LSI megaraid module. Boot log ends by a lot of lines:

RESET_GEN2: retry=xxx, hostdiag=a4

I tried CentOS 6.6 install disk and it also fails to find disks but CentOS 7 install disk boot fine.

It’s annoying to be stuck at 2.6.32-431 kernel and I have no idea how to solve this issue :-(

Thanks for any help.

  • works here fine on the 9261, which is an OEM version of the same card with the connectors in a different orientation… you might check your LSI firmware revision.

    My workaround is to install kernel-lt from elrepo repository. It seems to work well.

  • When I tinkered with CentOS and one of those LSI-cards a while ago, CentOS couldn’t find the card until the card’s BIOS was flashed with the latest firmware available at the time. After the flash, the CentOS stock-kernel found the card out-of-the-box.

    YMMV though.

  • That’s weird, because starting with 6.6 we could finally ditch inserting kmods at installation time, the new kernel in 6.6 supported everything. I believe the model we have (among others) is 9341-4i; I would imagine it’s pretty similar with what you have. You should open perhaps a bugzilla issue with redhat about this.

    Is it possible to post in Redhat bugzilla without a Redhat support contract ? Even when using CentOS ?

  • Yes, anyone can file a bugzilla report. It’s separate from the paid customer support ticketing system. There’s no SLA or obligation to respond to bugzilla as there is for paid support tickets.
