Question Re-Map SCSI Devices w/o Reboot


Let's say that I have 6 SCSI devices:
3:0:0:0 --> /dev/sdc
3:0:0:1 --> /dev/sdd
3:0:0:2 --> /dev/sde
-------------------
2:0:0:0
2:0:0:1
2:0:0:2

The first 3 are connected to SAN1 and the second set are connected to SAN2.

I want to backup the first 3 to local disk, remove them from the system (via /sys/bus/scsi/drivers/.../delete)
and then map the new disks to the old /dev/ entries. So we will now see:
3:0:0:0
3:0:0:1
3:0:0:2
-------------------
2:0:0:0 --> /dev/sdc
2:0:0:1 --> /dev/sdd
2:0:0:2 --> /dev/sde

Any ideas?

Thanks for the help,

-Dave
