When I install sl46 or sl47 x86_64 on Dell M600e blade ,and enable LVM
partition.
The harddisk will started as /dev/sdb. If i did not use LVM. It was no
problem, and started as /dev/sda.
I check the dmesg the scsi0 was assign to USB Mass Storage. But i did
not install any usb storage device.
I test sl53-x86_64, it was ok.
