7 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.

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.

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.
Figure 21
shows the location of the hard-disk drives on the front of the IP1200 Series.

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

of Nokia IPSO you are using.
