Description of problem:
After adding drives to a running 7.1 system, missing OS message occurs
after reboot. Found that drives were remapped after booting with the
parameter "root=/dev/sdb5" worked.
Steps to Reproduce:
1. Place unconfigured RAID adapter in PCI slot.
2. Install RH 7.1 to local drives with onboard Adaptec controller with
3. Attach cable from RAID adapter to external drives and configure RAID-5
4. Reboot system.
Actual Results: Missing OS. Red Hat load the ips driver first before the
aic7xxx and finds the RAID drives of which it tries to boot off of.
Expected Results: Boot into RH 7.1 successfully.
Passing the paramter "root=/dev/sdb5" works.
The drive has been remapped from sda5 to sdb5.
If this is a bug, it's an mkinitrd bug (or anaconda bug) where it should
have the root-device module as first module.
This will require implementing mount by label support in the initrd. It's not
planned for 7.1 or the next release.
