Chaparral G5312/G7313 User Manual

You can delete a dedicated spare drive from an array at any time.

From the System Menu, select Array Menu and press Enter.

The Select Array screen displays with a list of existing arrays.

Select the array you want and press Enter.

The Array Menu screen displays.

Select Delete Spare and press Enter.

Select the spare drive you want to delete and press Enter. 

The system confirms the deletion.

Select Yes and press Enter to delete the spare.

The drive is now available for use in an array or as a spare.

The Dynamic Spares option lets you use all of your disk drives in redundant arrays, 
without assigning one as a spare. For example, if you enable Dynamic Spares and a 
drive fails, you can replace the drive and the controller will rescan the bus, find the 
new disk drive, and automatically start reconstruction of the array. The controller 
automatically finds the new drive and reconstructs the array.

With Dynamic Spares enabled, if you have spares or available drives, the controller 
first looks for a dedicated or spare pool drive for the reconstruction. If none is found, 
it uses an available drive, which the controller automatically assigns as a spare and 
starts reconstruction.

You must make sure that the new or available drive has enough capacity to replace the 
smallest member in the array and does not contain metadata (see Clearing Metadata 
from a Drive on page 8-4).

Performance in systems without a SAF-TE Enclosure Processor 

(SEP) will decrease if an array becomes critical with this option enabled and 
there are no available drives to start a reconstruct. To minimize the 
performance impact, increase the rescan rate as described in the steps below.
