Well you guys have give me some good news but I have try something like that before.
I use to have a Dell r510 on witch I had 2 60gb ssd's connected on sata ports as that motherboard came with 5, but I then change to a Dell r910 that only came with 1 sata port for the optic drive. I try to use a H200 with those 2 ssd's connected on it but couldn't boot from them, then I feed a fresh install on 2 USBs thinking that I could recover my pools on the same way @herajust told me but I was never able to do it or find any information on how to do it, you guys like to say that many things can be done but never say how and hope for us (the unwise) to find up for our self's, but when you don't even have an idea of what you are doing turns to be pretty impossible. Well that time my solution was to put everything back on the r510 and resilver my ssd's in to 2 USBs and then just change everything to the r910 and it works perfectly.
Can you guys be so kind and give me more specific information or at least links on where can I find those methods as I have try to recover the pools on a new install and haven't being able to.
I have another issue of the same sort of well, I have 2 enclosures of 15 drives each on where I have another 2 pools, but if I turn on the server and forgot to turn on the enclosures to be detected on boot and do it afterwards, I have the same issue, I can see that I have the 15 disks from each enclosure but I don't see any why to make to pool to pop up or something, even though it says that the disks are there, the pool keep saying that is disconnected and if I go to pools and try to import, it just doesn't detected anything, so I guess there is another step that I am missing that I can't find anywhere. Neither on you tube or here, I have being having a lot of this issues and the most of the times is because I don't even know the names you guys give to the things and if you don't now how to look, you won't never find something.
