CentOS 4 installer sees /dev/sda, but after boot it's, /dev/sdb (jeff nichols)

[Tim Bell]

You can fix this with a change to the modprobe.conf and a new mkinitrd.

Put the scsi_hostadapter lines in for your system disks (such as below 
which we use for our 'old' blades)

alias scsi_hostadapter mptbase
alias scsi_hostadapter1 mptscsi
alias scsi_hostadapter2 mptspi
alias scsi_hostadapter3 mptsas
alias scsi_hostadapter4 mptscsih
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd


This means that the mpt* drives are loaded before the usb ones and so 
the /dev/sda is allocated to the first driver loaded.
