What happens when the module is loaded? Possibly closely related to https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=135484 I had much the same happen to me, except it wouldn't even show the devices in installation. Have you checked to make sure you are at the latest firmware level? My card wouldn't update, but yours might. Bill - Even if I manually load megaraid_mm/megaraid_mbox, I don't see the array. It used to show up as sdc. (I also have an Adaptec card with 2 drives attached to it.) Did something change with the kernel, or is this an udev problem? It used to work with the old kernel/devfs combination. Brian - My card isn't listed on the Manufacturer's site anymore. Given it's excellent history, I am less likely to believe it is a firmware problem with the card than a problem introduced by kernel/udev/devfs changes in FC3. Pete - OK, just thought I'd check. I show the MegaRAID 475 to be the direct transfer to the LSI Logic MegaRAID Express 500. (LSI bought all of AMI's RAID card business, as far as I can tell). Here's the downloads page for that card, but you'll be able to narrow down whether or not it is the same card far better than I. http://www.lsilogic.com/downloads/downloads.do?product=2453&download_type=all Good luck! I think whatever fixes your problems will likely fix mine, too! Brian Brian - Thanks for the link. It looks like it's for my card, but I got nervous while going through the readme.txt. The part about "MAKE SURE TO FLASH THIS FIRMWARE ONLY WHEN USING A MEGARAID 475/493/471/494/503 CONTROLLER FROM LSI LOGIC CORPORATION" will probably stop me from updating. Color me cautious on flashing my BIOS. =/ After a little more digging, I think it's a udev problem. `lspci -vv`
lists that the card is at address 00:0b.0 on the PCI bus. udevinfo for
this device reveals this:
# udevinfo -a -p /sys/devices/pci0000\:00/0000\:00\:0b.0/
udevinfo starts with the device the node belongs to and then walks up the
device chain, to print for every device found, all possibly useful
attributes
in the udev key format.
Only attributes within one device section may be used together in one
rule,
to match the device for which the node will be created.
looking at class device '/sys/devices/pci0000:00/0000:00:0b.0':
SYSFS{class}="0x010400"
SYSFS{detach_state}="0"
SYSFS{device}="0x1960"
SYSFS{irq}="137"
SYSFS{subsystem_device}="0x0475"
SYSFS{subsystem_vendor}="0x101e"
SYSFS{vendor}="0x101e"
It looks like the card is attached and responding, but the system
doesn't know what to do with it. I'm just starting to learn about
udev, however, so I may be completely off-base.
Upgrading the firmware to the latest version does not resolve this issue. The driver used for FC3 will not recognise any partitions on the MegaRAID Express 500 controller - regardless of firmware. Amazingly this made it out of test into the released version this week. I have yet to find a way to get the correct megaraid driver to load sinc e obviously the one included is defective and the old driver was excluded from the FC3 installer. I just upgraded to the full FC3 (from FC3-test2) and applied all of the released updates. Still no dice. Upgrading the kernel also gave warnings about no modules for megaraid or megaraid2. Has anyone had any luck with this? An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you. This bug has been automatically closed as part of a mass update. It had been in NEEDINFO state since July 2005. If this bug still exists in current errata kernels, please reopen this bug. There are a large number of inactive bugs in the database, and this is the only way to purge them. Thank you. |
