BMR may not format or clear the ZFS metadata
If you opt for the creation of a ZFS storage pool on small number of disks during a dissimilar disk restore (DDR), Bare Metal Restore (BMR) does not format or clear the ZFS metadata on the disks that remain. Because of that, if you attempt to use those disks to create other storage pools, you may see an error message that states a disk is in use under the ZFS storage pool.
To work around this issue, use the -f option to create a new storage pool on those disks.
