S.M.A.R.T. Configuration
9.1 Overview
S.M.A.R.T.
With the maturity of technologies like S.M.A.R.T., drive failures can
be predicted to certain degree. Before S.M.A.R.T., receiving
notifications of drive bad block reassignments may be the most
common omen that a drive is about to fail. In addition to the
S.M.A.R.T.-related functions as will be discussed later, a system
administrator can also choose to manually perform “Clone Failing
Drive” on a drive which is about to fail.
This function provides system administrators a choice on when and
how to preserve data from a failing drive. Although not necessary
under normal conditions, you may also replace any drive at-will
even when the source drive is healthy.
The “Clone Failing Drive” can be performed under the following
conditions:
1. Replacing a failing drive either detected by S.M.A.R.T. or
notified by the controller.
2. Manually replacing and cloning any drive with a new drive.
9.1 Clone Failing Drive
Unlike the similar functions combined with S.M.A.R.T., the “Clone
Failing Drive” is a manual function. There are two options for
cloning a failing drive: “Replace after Clone” and “Perpetual
Clone.”
