Description of problem:
Installing FC6 on a dual xeon supermicro with an onboard AIC-79xx plus an ZCR 20xx controlling both SCSI CD/DVDs and a RAID-10 crashes in the early steps if booting from a SCSI CD, as it is recognized until i2o module is mounted and then no more. Opposedly, if booting from an IDE CD/DVD, the partitioning utility does not see any RAID disk.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. As above in description
installation on RAIDs impossible
plain RAID installation
Maybe this is due to different behaviour of i2o module than older dpt_i2o module: on old documentation (Fedora Core 3 release notes.htm)I have found that on i2o modules drives are arranged as /dev/i2o/hd* instead of 'normal' /dev/sd*:
"I2O SCSI RAID adapters from manufacturers such as Adaptec now use the i2o_block driver, rather than the dpt_i2o driver used by Fedora Core 1 and earlier distributions.
Be aware that block devices used by the i2o_block driver are /dev/i2o/hd* rather than the /dev/sd* SCSI devices. This may be problematic for those upgrading from older distributions that used the dpt_i2o driver. Therefore, after an upgrade to Fedora Core 3, you may need to boot using a rescue disk and edit your /etc/fstab file to use the new devices."
