Description Wendy Hung 2001-08-13 14:12:31 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT)

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. 

How reproducible:
Always

Steps to Reproduce:
1. Place unconfigured RAID adapter in PCI slot.
2. Install RH 7.1 to local drives with onboard Adaptec controller with 
root=/dev/sda5  
3. Attach cable from RAID adapter to external drives and configure RAID-5 
array.
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.

Additional info:

Passing the paramter "root=/dev/sdb5" works.
The drive has been remapped from sda5 to sdb5.
Comment 1 Arjan van de Ven 2001-08-17 11:15:34 EDT
If this is a bug, it's an mkinitrd bug (or anaconda bug) where it should
have the root-device module as first module.
Comment 2 Matt Wilson 2001-08-17 11:22:55 EDT
This will require implementing mount by label support in the initrd.  It's not
planned for 7.1 or the next release.
