Trying to install CentOS 7.0 on a Dell PowerEdge 2850 with a PERC 4e/Di RAID card with all drives installed as one logical drive (raid 5, if it matters.)<br />
<br />
The CentOS 7.0 installer does not see the device at all. Alas, I did not save the dmesg output for y'all, but I can go back and get it if needed.<br />
<br />
CentOS 6.5 works fine on this hardware. CentOS 6.5 reports this for it in the dmesg output --<br />

Again, all of this data was collected under CentOS 6.5, not CentOS 7.0.<br />
<br />
Since the install DVD kernel doesn't see the raid controller, anaconda cannot install to it. I don't know if the kernel that is installed has support for this device or not -- I just know that the install DVD doesn't seem to.<br />
<br />
Sorry if "kernel" wasn't the ideal project to put this under. I'm not sure if I should have done that or "anaconda", but "kernel" seemed more correct.
