SCSI disk names change when adding / removing devices.

[Naoki]

Hi all,

    I have a problem, when I install my OS ( FC2 ) on my nice machine 
with an internal scsi controller my two disks are sda and sdb, which is 
all nice and expected.  But then when I add a new scsi card and hook up 
the external disk array the new array now becomes sda which has a very 
negative effect, can't boot..

Any helpful hints?  I could label the disks sure but then swap is still 
on sda2 and that's a problem.
