1 Overview Hard-Disk Drives The Nokia IP1200 Series appliance supports up to two hard-disk drives. The hard-disk drives support hot swapping, and an optional disk-mirroring feature, described in the following section. Disk Mirroring The Nokia disk-mirroring feature provides fault tolerance by allowing the IP1200 Series appliance to continue working in the event of a disk failure. You can create mirror sets that consist of a source hard-disk drive (which holds the active copy of the operating system) and mirror hard-disk drive. The mirror hard-disk drive contains a copy of all of the files on the source hard-disk drive, and if the source hard-disk drive fails, the mirror hard-disk drive immediately takes over. The IP1200 Series appliance continues to operate normally, and the switchover to the secondary mirror drive should be transparent to your data connections. You can use Nokia Network Voyager, the command-line interface (CLI), or Lynx to create and delete mirror sets. Note The IP1200 series flash-based appliances do not support disk mirroring. For more information about disk mirroring, including configuration details, see the Nokia Network Voyager Reference Guide and the Nokia IPSO Getting Started Guide and Release Notes for the version of Nokia IPSO you are running. Hard-Disk Drive Hot Swap Feature If you configure disk mirroring, you can use the hot swap button, shown in Figure 5, to remove or replace a hard-disk drive without shutting the appliance down.

Hard-Disk Drives
The Nokia IP1200 Series appliance supports up to two hard-disk drives. The hard-disk drives
support hot swapping, and an optional disk-mirroring feature, described in the following section.
Disk Mirroring
The Nokia disk-mirroring feature provides fault tolerance by allowing the IP1200 Series
appliance to continue working in the event of a disk failure. You can create mirror sets that
consist of a source hard-disk drive (which holds the active copy of the operating system) and
mirror hard-disk drive. The mirror hard-disk drive contains a copy of all of the files on the
source hard-disk drive, and if the source hard-disk drive fails, the mirror hard-disk drive
immediately takes over. The IP1200 Series appliance continues to operate normally, and the
switchover to the secondary mirror drive should be transparent to your data connections.
You can use Nokia Network Voyager, the command-line interface (CLI), or Lynx to create and
delete mirror sets.
Note
The IP1200 series
flash-based
appliances do
not
support disk mirroring.
For more information about disk mirroring, including configuration details, see the
