From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; H010818; .NET CLR 1.0.3705) Description of problem: New megaraid_mbox driver in RHEL4 Beta2 disables support for the following controller: VID:0x101e DID:0x1960 SSVID:0x1028 SSID:0x0511 Description: PowerEdge Cost Effective RAID Controller (CERC) ATA100/4ch Version-Release number of selected component (if applicable): kernel-2.6.9-1.648_EL.src.rpm How reproducible: Always Steps to Reproduce: 1.Install RHEL4 Beta2 on disks connected to a CERC ATA100/4ch controller. 2. Installer loads megaraid_mbox driver but when creating partitions it gives "no disk found" message . 3. Actual Results: Should be able to install on disks connected to CERC ATA100/4ch controller. Additional info:
The megaraid driver has been split into two separate drivers with the 2.6.9 kernel, megaraid_mbox and megaraid_mm. Can you try manually loading the megaraid_mm module and seeing if that identifies discs on the controller? Still sounds like there might be an issue if anaconda is loading the megaraid_mbox module which then fails to find any drives, so please confirm that's indeed what is happening. Thanks.
The problem is that LSI (in conjunction with Dell Storage) decided to remove PCI IDs from the megaraid_mbox driver without making a megaraid_legacy driver available which handled the IDs they removed. All cards prior to Dell PERC3, which includes the CERC ATA100/4ch have become unsupported by LSI for RHEL4 and newer, and they wanted to remove PERC3-series too. :-( megaraid_mm is the 'management module' portion of the driver, it doesn't handle any PCI IDs itself. It's what claims the /dev/megaraid device node on behalf of any additional drivers (currently only megaraid_mbox).
OK, now I'm confused. Do we have a problem from Dell's standpoint? Or is the megaraid_mbox driver support "OK" for now, in which case this bug can be closed?
"unsupported by LSI for RHEL4" So is this a bug or not? Set to NEEDINFO.
We've got a discussion this afternoon with Dell's Storage team that interacts with LSI. From an engineering perspective it's NOTABUG, the driver implements the Dell Storage / LSI approved list of cards for RHEL4. However, from a marketing and customer support perspective, that approved list may need to have this card added back in, in which case the driver will need to add the ID back also. I'll leave in NEEDINFO state for another day or two while this gets resolved internally.
Matt: what happened in the discussion last week with your Storage folks? In our estimation, LSI has dropped the ball; have they explained to you how your older hardware will be supported?
At this point, neither LSI nor Dell's Storage team will be supporting the CERC ATA/100 raid card in RHEL4. Therefore I'm closing this as NOTABUG, it's working as designed per Dell's requirements. IT54525 is open to track the list of no-longer-supported hardware for your release notes. I added CERC ATA/100 4-channel to that list.

I understand that Dell's storage team isn't supporting the CERT ATA/100 RAID card, but as noted there are still a lot of units out there that are working fine in boxes suitable for a broad range of uses. Trust me, we (Carleton College) buy plenty of Dells for a small college (dozens of servers a year and I don't want to even think how many desktops). At the very least, I'd love to see an unsupported old-style megaraid driver made available so I can use these old boxes to test RHEL 4.0 before we put services into production.
