E.2 Enabling Dynamic Spares
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.
Note
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.
