CTERA C200: Degraded Hard Drive Replacement

One thing you may come across when using the CTERA C200 is a degraded hard drive. But don’t worry; this is a common issue.

It’s normal for hard drives to go bad, especially after several years of service. Luckily, the RAID1 configuration allows the drives to run in a degraded state, giving you extra reaction time to order a new drive and get it replaced.

Here’s a tutorial on how to find and replace a failed disk drive in your CTERA C200 unit.

Finding the Failed Disk Drive

Under the “Storage” tab, navigate your way to the “Arrays” category. On this screen, you will see your list of arrays along with their statuses. This is where you will look for the one that reads: “Degraded.”

In order to find the disk drive that is causing this error, navigate to the “Dashboard” under the “Main” tab.

Note: If the device is degraded, it’s normal to operate a bit sluggish.

Once the dashboard loads, your hard disk drives will be displayed near the top. Look for the one with “Failed” written in small, red print underneath it. This is your fault disk drive.

Now it’s time to replace it.

(The CTERA C200 doesn’t have to be shut down in order to change disk drives.)

Replacing the Failed Disk Drive

To begin replacing the failed disk drive, you must first remove the failed disk.

Go to the “Storage” tab and click on the “Arrays” category. Click on the degraded array and un-check the box that gives it member status. A pop-up wizard will ensue; click your way through it until the CTERA instructs you to remove the faulty disk.

Remove the failed disk, and insert a new one into its place. Once the CTERA recognizes the new disk, you have to format it.

Go back to the “Dashboard” on the “Main” tab and click on your new disk drive. On the pop-up window, click “Format.”

Go back to “Arrays,” click on the new one and give it members status. The arrays disk drives will then begin to synchronize.

Note: Depending on how much data you have, the synchronization can take up to a day.
