You can manage the disk drives installed in the BIG-IP® system using the Configuration utility.
Platforms that contain more than one disk drive support drive mirroring using RAID. In an array of two disks (for example, HD1 and HD2), the mirrored volumes are named MD1.1, MD1.2, and MD1.3.
On platforms containing only a single disk drive, the volumes are named HD1.1, HD1.2, and so on.
