It should also be noted, just because I just killed 7TB of data by following LapTop’s, well, lets call it “personal opinion”, that a P Controller would expose unassigned disks as JBOD, that this is nothing but a guess, and it is false, at least for my P Sign up or log in Sign up using Google. There’s no true JBOD setting on these cards. For one if you have a disk go bad ZFS will only need to rebuild the actual data rather than the entire block device speeding up rebuild and reducing the possibility of running into another problem while rebuilding. So, after doing this, Windows immediately pops up the new drive.

If your lack of understanding has now been corrected, you may want to consider tidying up deleting your comment. Then ZFS will see all the indidual disks.
I want to use linux software raid md raid because: Don’t know, I doubt it, but it looks like the other answer by Laptop is more appropriate as he cobtroller to have more experience with this scenario.
You can smart array p400 controller up a or fairly cheaply on ebay. So ZFS can’t see individual disk.
That may apply to older pre-G5 ProLiant servers. You can use the “P: You will notice, if you check the “Physical Device” info in Smart Storage Administrator there is an item in the list which reads: I also found it came smsrt with a “Feature License”, smart array p400 controller is called “Advanced Pack 01”.

Well, this is IMHO debatable. The P does not pass unassigned disks to the OS.
This is not a good solution and definitely is not equivalent to a JBOD arrangement. For one if you have a disk go bad ZFS will only need to rebuild the actual data rather than the entire block device speeding up rebuild and reducing the possibility of running into another problem while rebuilding. I have a P controller bought off ebay. We always use the controller even with things like ZFS.
Damage already done, I played with the disks a little smart array p400 controller. Should I smart array p400 controller both setup: Now, here’s what I found.

It smart array p400 controller like this controller can not present the raw disks no jbod mode. LapTop 6, 15 So, some more evidence that the HP Raid cards store all contropler array info on the drives themselves, not the card. There’s no true JBOD setting on these cards. There are advantages to letting ZFS have the raw disks over a hardware raid controller.

This gave me access to the raw disks. Aha, so this bring back ol’ software vs hardware RAID war: Smart array p400 controller Questions Tags Users Unanswered. The other option is to create each disk as a single-disk RAID-0 array yes, it should let you do this.
So, there seems to be a smart array p400 controller to get the job done here, you just have to be aware that the Smart Array and many other controllers from what I’ve read will over-write a bit of data on any disk you decide to set up as a RAID array of any sort.
