Uhm, no, it's not. The stock Linux kernel maps SCSI drives in the order
that it finds them. The first SCSI disk is /dev/sda, the second is
/dev/sdb, the third, /dev/sdc, and so on. /dev/sdb1 is the first partition
on the second SCSI drive. If you add another SCSI disk that the kernel
finds earlier, then that disk will no longer be /dev/sdb, but some other
disk. Persistent superblocks make sure that your RAID arrays can start up
even when you change the number of SCSI disks in your system.
