why not just experiment and find out? put two disks on a single channel, make the raid, power down, move the slave to another channel, and see if the raid assembles.
One word: time; I was hoping someone could tell me if it would work to save me messing around. Of course, if I plan to do this I will perform some sort of test first.
The answer is yes it will work fine. I had 5 200gb WD disks set as autodetect raid-5 My internal VIA IDE interfaces were hda/b/c/d My external CMD680 IDE interfaces were hde/f/g/h
I had raid disks on c/d/e/f/g. I created the raid and ran it for months, then I shuffled the disks and master/slave jumpers. No problems. I then purchased a couple of Highpoint 1540 SATA cards and a bundle of addonics SATA-> IDE adaptors. Using the in-kernel hpt ata driver, no problem. I then moved across to a pair of Promise SATA150-TX4 cards with the libata driver, no problem.
So as you can see, these disks have been "everywhere man" and I never had a problem with the kernel or appropriate tools picking them up in any order.
