Modifying Logical Drives (migrating)
The Migrate Logical Drive action enables you to
- migrate the RAID type to a different type
- expand the capacity of the logical drive
Note:
Most operating systems of today support Online Capacity Expansion (OCE).
OCE means that the additional capacity after a logical drive has been
expanded can be used without rebooting the system. Details on the additional
storage capacity are provided in the documentation for your operating system.
To make a modification select a logical drive
(
)
in the tree structure and start the Migrate logical drive action (via the pulldown
menu of the Actions button or with a right mouse click). A dialog box is opened
which contains Parameters and Layout.
- Select the new RAID type in the pulldown menu. The migration
options here depend on the RAID controller used.
- Under Layout you can – if you are offered the option – expand
the capacity by selecting hard disks in the tree structure and adding them to the logical
drive using the Add button. You activate your modifications using the Apply button.
After you have pressed the Apply button you must confirm the modifications again. If
you quit one of the dialog boxes using Cancel no changes are made.
The following rules apply for modifying a logical drive:
- Select the new RAID type for a migration. If the required type
is not supported directly by the controller, you can then only delete
the logical drive and create a new one.
- The capacity of the new logical drive must be at least the same
as that of the current drive. If the capacity or the RAID type of the
new logical drive requires a greater overall drive capacity than the
current one, the additional capacity must be provided by the physical
drives which are not yet used in this logical drive. In this case
please select one or more physical drives which have sufficient
free capacity.
Note:
The name of a logical drive can – depending on the controller – be modified
in the properties (Settings tab) of the logical drive.
