Remove a Spare

The Remove spare option appears only if you have a RAID array with a spare disk

allocated to it.

Click Remove spare to start the Remove Spare Wizard and then follow the

instructions.

You can press F1 to access the online help that walks you through the Wizard with

step-by-step instructions.

Migrate an Array

In a traditional RAID environment, when a user wants to change the current state of

a disk or a current array to a new RAID configuration, the process of reconfiguring

the new array involves multiple steps. The user must back up the data, delete the

array, re-boot the PC, and then reconfigure the new array.

MediaShield RAID allows the end user to change the current state of the disk or array

to another with a one-step process called "Migrating". This section describes the

NVIDIA Migrating process and explains how to use Migrating to convert from one

RAID array type to another.

General Migrating Requirements

• The new array capacity must be equal to or greater than the previous array.

For example, it is possible to migrate from a RAID 1 array to a RAID 0 array as

long as the RAID 0 array is the same size as (or larger than) the RAID 1 array.

• The number of disks in the new array cannot be less than the number of disks in

the original array.

• You cannot migrate

- To or from a JBOD (Spanning) array

- From RAID 1 to RAID 1

- From RAID 0+1 to RAID 1

- From RAID 5 to 1

Migrating to an Array Larger Than 2 TB

Your disks must be partitioned using the GUID partition table (GPT) if you

plan to migrate to an array with greater than 2 TB storage.

If your original array is not a GPT disk and you expand your array’s capacity using the

migration feature to over 2 TB, you will not be able to access the additional storage

above 2 TB in the new array. To use the additional storage in this situation, back up

your data, repartition the array using GPT, then restore your data to the new volume.

Important

Be sure to make the volume dynamic if you plan to have more than four

partitions.
