Does the drive port matter when reassembling FreeNAS?

[NASbox]

Hope someone can help me here:

I have a FreeNAS 8.3.1 box that I had to take down for fan replacement.

Box has two pools, P1 RAIDZ2 - ada0,1,2,3
and P2 RAIDZ1 - ada4,5

The box was shut down properly, but I didn't export the volumes because I thought everything was labeled and could be put back exactly as it was taken apart.

No problem with P1, but it turns out that I didn't label P2, so I'm not sure which drive should be ada4 and which drive should be ada5.

If I get the two drives backwards will it matter?
How should I proceed to minimize the chances of screwing things up?

Thanks in advance.

Should not matter at all. One of the beauties of FreeNAS, just let it have direct access to the drives and it takes care of the rest.

Drive order doesn't matter

ZFS recognizes disks by a label that is written in metadata, so they do not need to be attached to the same port or even same controller.

Thanks all... especially appreciate this "ZFS recognizes disks by a label that is written in metadata, so they do not need to be attached to the same port or even same controller." This is very helpful going forward.

I did guess right anyway, but it's great to know
