Managing Spares

Select the array you want and press Enter.
The array menu 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 SM will rescan the bus, find the new disk drive, and automatically start reconstruction of the array. 
The SM automatically finds the new drive and reconstructs the array.

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

F.1.2, ”Clearing Metadata from a Drive”, on page 177

).

A change to this setting on either SM is automatically updated on the other SM.

Performance in systems without an enclosure management processor (EMP) will decrease if an array 
becomes critical with this option enabled and there are no available drives to start reconstruction. To 
minimize the performance impact, increase the Galaxy 65 Subsystem rescan rate as described in the 
steps below.

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

The Option Configuration screen displays.

Select Dynamic Spare Configuration and press Enter.
