IMO, yes (maybe). When the Initial install is done, I think there is some stuff that is needed in the initrd to find the disk so root can be mounted. I'm not sure which initrd file contains it, but I think it's got to be there somewhere. There are some more considerations I had forgotten.
Thanks, this gave the the hint I needed.
Looking at the original modprobe.conf file, there was no entry in it for the driver for the second SATA controller.
So to recover I booted the install CD in "linux rescue" mode.
Ran "chroot /mnt/sysimage"
I added
alias scsi_hostadapter1 sata_promise
to /etc/modprobe.conf
Changed to the /boot directory
mv initrd-2.6.18-128.1.6.el5.img initrd-2.6.18-128.1.6.el5.old
mkinitrd initrd-2.6.18-128.1.6.el5.img 2.6.18-128.1.6.el5
After that completed, I rebooted and the system came up clean--no fsck requested or any other oddities, system-config-lvm seems to be working fine.
No mucking about in /etc/fstab was needed.
Glad all worked out. I now remember why I had to do fstab. I had some duplicated backups on the hard drives that would be used if the primary drive failed. During testing booting from the second drive, I needed VolGroup00 to be VolGroupAA and other similar changes. This is what also required changes in the init file in the initrd. There is an --ignorelockingfailure imperitive that references the real root. For fallback testing, it needed to reference the fallback (VolGroupAA) volume.
