5.2.2 Downing a Drive
The xStack Storage Management Center provides a Down Drive feature that lets you remove
a drive from the system in an orderly way. Using this feature, you can, for example, replace
a smaller drive with a larger drive.
The Down Drive operation requires all space used on the selected drive to be relocated onto
different drives. The Down Drive feature handles this requirement by performing a
reconfigure task on every volume that uses space on the drive. This operation is conducted
for any type of volume, including redundant and non-redundant organizations.
To down a drive:
4. In the Physical Storage View, select a drive in the Main Display.
5. Perform one of the following steps:
–
On the Storage menu, click Down Drive .
–
Click Down Drive in the Drive Actions panel.
–
Press the right mouse button and click
Down Drive
on the shortcut menu.
Any of these steps displays the message in Figure 5-3.

7. Click OK in the box to remove the message.
There must be sufficient available capacity on other hard drives to
accommodate the relocation of all volumes. It must also be possible
to maintain the drive allocation rules for each of the volumes that are
to be relocated (for example, parity volumes require at least three
different drives to be used).
