devfs rescanning?

I have a system with 4 SCA drives. Originally they were:

/dev/sda -> scsi/host0/bus0/target0/lun0/disc
/dev/sdb -> scsi/host0/bus0/target1/lun0/disc
/dev/sdc -> scsi/host1/bus0/target0/lun0/disc
/dev/sdd -> scsi/host1/bus0/target1/lun0/disc

SDA drive was hot-pulled to test the raid failover and it worked great. Next the box was rebooted after the drive was replaced (these systems can hang or go real stupid when a drive is pulled). The drives remapped as was expected. When it came back up the sd? entries had shifted up 1 as expected

/dev/sda -> scsi/host0/bus0/target1/lun0/disc
/dev/sdb -> scsi/host1/bus0/target0/lun0/disc
/dev/sdc -> scsi/host1/bus0/target1/lun0/disc

and when the drive was put back in it came up as sdd. Other than a reboot is there any known way to get the drives back in the proper order? Killing devfsd, removing the entries and restarting, etc didn't do any good.
