Security Gateway Manual Netgate-4200
Caution: If this device contains multiple disks, such as when adding an SSD to an existing system which pre-
viously used MMC, additional steps may be necessary to ensure the device boots from and uses the correct disk.
Furthermore, having separate installations of the software on different disks is a known source of problems. For
example, the kernel could boot from one disk while the root filesystem is loaded from another, or they could contain
conflicting ZFS pools.
In some cases it is possible to adjust the BIOS boot order to prefer the new disk, but the best practice is to wipe the
old disk to remove any chance of the previous installation causing boot issues or conflicts.
For information on how to wipe the old disk, see Multiple Disk Boot Issues.
