Hello,

Are you having an issue you are troubleshooting?

If so can you provide any details?

Below are steps for removing and installing a controller:

Before Moving the Controller

1. Backup Configuration:
• Yes, you can and should back up the configuration before making any hardware changes.
• Use Dell Storage Manager (DSM) or Enterprise Manager to create a backup of the system configuration.
• Navigate to System > Backup/Restore in DSM and follow the prompts to export the configuration.
2. Check Firmware Compatibility:
• Ensure both SC5020 systems are running the same firmware version.
• Mismatched firmware can cause boot or compatibility issues.
3. Label and Document:
• Label all cables and connections.
• Document IP addresses, WWNs, port mappings and any custom settings.

Moving the Controller

1. Power Down the Controller:
• Gracefully shut down the controller you plan to move using DSM or the front panel.
2. Remove the Controller:
• Follow the steps in the SC5020 Owner’s Manual to safely remove the controller.
1. Remove a Storage Controller Page 18-20
2. Install a Storage Controller Page 20-21
3. https://dl.dell.com/topicspdf/storage-sc5020_owners-manual_en-us.pdf
•  
• Use anti-static precautions and handle the controller carefully.
3. Install in the Target System:
• Insert the controller into the same slot (A or B) in the target SC5020 chassis.
• Ensure it is seated properly and all connections are secure.
4. Reconfigure Network and System Settings:
• On boot, the controller may retain its original configuration.
• You may need to reset or reassign IP addresses, host mappings, and other settings to match the new environment.
