Installer doesn't recognize i2o disks

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2) Gecko/20040803 Description of problem: Fedora Core 2 installer does not show disks connected to an i2o controller (in this case a adaptec 3200S SCSI RAID card). The i2o modules seem to load fine but there is no entry in the /dev directory for any of the disks (i.e.-> /dev/i2o/hd[a-z]) Furthermore, once the install is complete and the system has been rebooted the disks can be seen by the system. (i.e. -> /dev/i2o/hd[a-f]) Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Install FC2 onto a system with disks attached to a i2o controller 2. Attempt to partition the disks attached to the i2o controller Actual Results: None of the disks attached to the i2o controller were available to be partitioned. Expected Results: disks attached to the i2o controller should have shown up in Disk Druid so that they were available to be partitioned. Additional info: I was not using the hardware RAID feature of this controller but rather attempting to address the individual disks.
i2o disks aren't supported for installation with FC2. The kernel didn't really export enough information for me to be able to probe them.
THIS IS ABSURD!!!. I2O devices were supported under Fedora Core 1. So newer versions of Fedora loose hardware support?. Every other distribution I have tried supports the I2O devices. Shall we choose a different distribution?. Diego Remolina
Fedora Core 1 was 2.4 not 2.6, what kernel versions were the "other distributions". This bug is for FC2 which as Jeremy says there wasn't enough exposed information: The current i20 support is described here: http://i2o.shadowconnect.com/fedora.php FC2 Howto: http://www.redhat.com/archives/fedora-list/2004-May/msg03906.html Faq: http://i2o.shadowconnect.com/faq.php
Well, FC3 Test 3 handles I2O correctly, so I will wait to install the system using FC3 when it gets release status (hopefully a couple of weeks more at most). The "other distributions" I tried where gentoo and knoppix using the 2.6.7 kernel. I also noticed other distros handle i2o devices as /dev/sda* and that Fedora Core 3 does /dev/i2o/hda. Is there any special kernel modification on the FC3 kernel for i2o devices? Diego
The Howto on: http://www.redhat.com/archives/fedora-list/2004-May/msg03906.html ... works like a charm. So there is really support to install I2O devices with FC2 if you get the missing module and add it. From the link above: " 1) Unpack the kernel RPM for your FC2 installer. 32bit is the "i586" kernel, and 64bit is the "x86_64" kernel. Use a command like: rpm2cpio kernel-2.6.5-1.358.i586.rpm | cpio -idv NOTE: Use the i586 kernel and NOT the i686. 2) Take the i2o_proc.ko module and put it on a web server somewhere. 3) At the first screen of isolinux, use "expert askmethod" as a boot option. Do any network install where you manage to get online. 4) When it asks if you want to load any driver disks, go into ALT-F2 terminal and wget the module into /tmp. Use insmod to load that module and lsmod to verify that it was loaded. NOTE: insmod -p /tmp i2o_proc.ko 5) Go back into Anaconda and go through the next few screens. Disk Druid should now see the i2o disks. Everything *SHOULD* work now. At least it did for us in testing. 6) After installation you wont ever need the i2o_proc module again, and it should *JUST WORK*. If not report your results here and I will try to help. " Diego
