Each step must be executed carefully to avoid any potential data loss or system issues.

Identifying the Faulty HDD

To identify the faulty HDD, check the system’s management interface for alerts or warnings. The interface will typically show which drive has failed.

Look for indicators such as a red light on the drive bay or a ‘Failed’ status in the management software.

Next, verify whether the drive was part of a RAID configuration. If so, note down the affected RAID level and the specific disk number. This information will guide the next steps in the replacement process.

Removing the Faulty HDD

Once the faulty HDD is identified, it is time to safely remove it.

First, ensure that the array is in an appropriate operational state before removal. The system may allow for hot-swapping, meaning the array can stay active while the drive is replaced.

To remove the drive, locate the latch or release mechanism on the drive bay. Grasp the handle firmly and pull it straight out to avoid damaging the connectors.

Place the faulty HDD in an anti-static bag to protect it from static electricity and set it aside for disposal or recycling.

Installing the New HDD

With the faulty HDD safely removed, installing the new HDD can begin.

Verify that the replacement drive matches the specifications of the original.

This includes checking the size, speed, and interface to ensure compatibility with the system.

Insert the new HDD into the empty drive bay, aligning it with the connectors.

Firmly push until you hear a click that signals the drive is securely in place.

After installation, monitor the management interface to confirm the new drive is detected and part of the RAID configuration.

If needed, initiate a rebuild process to restore redundancy.

Post-Replacement Procedures

After replacing the HDD in the EMC Clariion CX4-120, it is crucial to ensure that the new drive is properly integrated into the system.
