5.4.12 Using the Down Drive Feature
The xStack Storage Array provides a Down Drive feature that allows a drive to be removed from
the system in an orderly way. Using this feature, you can, for example, replace a smaller drive
with a larger drive, or replace a drive for which S.M.A.R.T. has projected a failure. The xStack
Storage Array can perform up to five concurrent Down Drive operations at one time.
The Down Drive operation requires all space used on the 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.
When all space has been moved off the drive, the drive is moved to the
Unusable Pool
and can
be removed from the system.
5.4.12.1 Initiating the Down Drive Operation
To use the Down Drive feature, right-click the drive you want to remove and click
Down Drive
.
The Down Drive task appears in the task pane of the xStack Storage Array management console.
One reconfigure task is created automatically for each volume that used space on the selected
drive. The reconfigure tasks are issued one at a time. The progress of the Reconfigure and Down
Drive tasks can be monitored on the task pane.
