10.2 Fault Prevention With the maturity of technologies like S.M.A.R.T., drive failures can be predictable to a certain degree. Encountering drive bad block reassignments may be the most common omen when a drive is about to fail. In addition to the S.M.A.R.T.-related functions as will be discussed later in this section, a system administrator can also choose to manually perform “Clone Failing Drive” to a drive which is about to fail. System administrators can decide when to replace a drive showing symptoms of defects by a healthy drive. A system administrator may also replace any drive at will even when a source drive is healthy. Usually, the “Clone Failing Drive” can be performed under the following conditions: 1. Replacing drives about to fail either detected by S.M.A.R.T. or notified by controller. 2. <strong>Manual</strong>ly replacing and cloning drive data on any drive to a new drive. 10.2.1 Clone Failing Drive: Unlike the similar functions combined with the S.M.A.R.T. setting, the “Clone Failing Drive” is a manual function. There are two options for cloning a failing drive: “Replace after Clone” and “Perpetual Clone.” Replace after Clone: Data on the source drive, the drive with predicted error (or any selected member drive), will be cloned to a standby spare and replaced later by the spare. The status of the replaced drive, the original member drive with predicted error, will be redefined as an “used drive.” System administrators may replace the used drive with a new one, and then configure the new drive as a spare drive. Locate the logical drive to which the specific member drive with predictable error belongs. Select the “clone failing drive” function. Select “Replace After Clone.” The controller will automatically start the cloning process using the existing “stand-by” (dedicated/global spare drive) to clone the source drive (the target member drive with predicted error). If there is no standby drive (local/global spare drive), you need to add a new drive and configure it as a standby drive. Advanced Configurations 10-17
10-18 The cloning process will begin with a notification message. Press [ESC] to proceed. The cloning process will be indicated by a status bar. You may also quit the status bar by pressing [ESC] to return to the table of the connected drives. Select the drive indicated as “CLONING” by pressing [ENTER]. Select “clone Failing drive” again to view the current status. You may identify the source drive and choose to “view clone progress,” or “abort clone” if you happen to have selected the wrong drive. When the process is completed, users will be notified by the following message. <strong>Infortrend</strong>
