6.14 Setting a volume active
This operation applies to primary volumes on basic MBR disks.
To specify the volume from which the machine will start, you need to set a volume to become active.
A disk can have only one active volume, so if you set a volume as active, the volume, which was
previously active, will be automatically unset.
To set a volume active
1. Right-click the primary volume you want to set as active, and then click Mark as active.
If there is no other active volume in the system, the pending volume setting active operation
volume will be added.
Note: By setting the new volume active, the former active volume letter might be changed and some of the
installed programs might stop running.
2. If another active volume is present in the system, you will receive a warning that the previous
active volume will no longer be active. Click OK in the Warning window to add the pending
volume setting active operation.
Even if you have the operating system on the new active volume, in some cases the machine will not be
able to boot from it. You will have to confirm your decision to set the new volume active.
The results of the pending operation are immediately displayed as if the operation had been
performed.
To perform the pending operation you will have to commit it (p. 23). Exiting the program without
committing the pending operations will effectively cancel them.
6.15 Adding a mirror
Mirrored volumes provide fault tolerance by storing two exact copies of data—called mirrors—on
two different disks.
Adding a mirror to a basic or simple volume means converting that volume to a mirrored volume,
which involves copying the volume's data to another disk.
To add a mirror to a volume
1. Right-click the basic or simple volume to which you want to add a mirror, and then click Add
mirror.
2. Select the disk on which you want to place the mirror. The disks that do not have enough
unallocated space to create the mirror are not available for selection.
If you are adding a mirror to a basic volume or are placing the mirror on a basic disk, you will
receive a warning that the corresponding disk (or disks) will be converted to dynamic.
3. Click OK to add the pending addition of a mirror to the volume operation.
The results of the pending operation are immediately displayed as if the operation had been
performed.
To perform the pending operation you will have to commit it (p. 23). Exiting the program without
committing the pending operations will effectively cancel them.
Important! If this operation was performed with machine rebooting or by using bootable media, the dynamic
volume will get the Failed redundancy status after booting into any edition of Windows 2003. To repair the
