Howdy all. We're experiencing some difficulties encountered from a new build/install world/kernel on a Compaq Proliant machine we have. We were running fine under 4.7-STABLE, and updated the sources to 4.8-STABLE last night (5/8/03), built and installed. This morning after a reboot, we got a horrid error to the likes of: Error mounting root. Error no 22. We encountered this error earlier this week on -CURRENT, but it has since been fixed. However, I haven't seen any GEOM MFC's, so I'm not sure what the problem is. Anyway, we were able to boot with a floppy that happily loads the boot block and loader, and gladly loads the kernel (and doing 'ls' from the loader prompt shows the root partition just fine, and 'show' in the loader prompt shows 'currdev=disk1s1a) but once the kernel waits for SCSI devices to settle, the system drive (there are 5 devices on the SCSI bus, 0 thru 4) vanishes (device 0), thus moving devices 1-4 down and becoming 0-3. This is a problem, as drives 1-4 (or 0-3 now), were a vinum RAID5 array. There is no valid root partition on that array, and since the kernel can't see the REAL drive 0 (da0 or bios disk1) anymore (the loader could), it can't see the root partition. These Compaq Proliants don't have a real BIOS configuration without installing a DOS partition on your system drive, so you just can't set the boot device to IDE. The 4.8 kernel recognizies the proliant's SCSI as a sym0 and sym1 devices (875 is in parenthesis, and I believe it's the chipset number). Question being, anybody experienced anything similar with Compaq proliants not seeing the system disk when booting from a floppy or the primary system disk (SCSI)? We're going to try and rever to an older kernel (4.7) and see if anything remarkable happens, but I'd like to probe the waters and see if anybody has any other ideas. Thanks for any and all suggestions/help. Cassidy.
