Installing and Replacing Components Other than Network Interface Cards (NICs) and Accelerated Data Path
Replacing a Hard-Disk Drive
The Nokia IP1200 Series appliance supports up to two hard-disk drives with the disk mirroring
feature in the Nokia IPSO operating system. If the appliance has only one hard-disk drive
installed, it is in the top slot (slot A). You can add a second hard-disk drive into the bottom slot
(slot B) or replace the hard-disk drive in slot A.
This section describes how to remove and replace a failed hard-disk drive,
and how to add an optional second hard-disk drive to implement the disk-mirroring feature.

Disk Mirroring
The Nokia disk-mirroring feature provides fault tolerance by letting the Nokia IP1200 Series
appliance 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 continues to operate normally.
You can use Nokia Network Voyager, the command-line interface (CLI), or Lynx to create and
delete mirror sets.
Note
If your IP1200 Series contains two hard-disk drives when you receive it, the disk-mirroring
feature is already enabled. Disk mirroring is not supported on flash-based appliances.
For more information about disk mirroring, including configuration details, see the Nokia
Network Voyager Reference Guide and Getting Started Guide and Release Notes for the version
of Nokia IPSO you are using.
