[SASAG] udev and hot-swap drives

Recently I had a drive failure on one of our Linux servers that uses md
Upon replacing the drive (hot-swap) which was /dev/sdb (for example) it
was recognized instead as /dev/sde.
In other words it didn't assume the previous device identifier.
I attempted to rectify this with soft-links e.g. /dev/sdb -> /dev/sde
but it didn't pan out.
So I rebooted the server and the drive was then correctly identified as
/dev/sdb which allowed the md array to be rebuilt.
Is there a way to coerce udev to remap a device on the fly or how could
I have handled this better i.e. to avoid the reboot?
P.S. I realize hardware RAID would usually handle this situation fine.
I hate racists.
