Question 66 - D-PSC-MN-01 discussion

When replacing a system board (motherboard) on a Dell EMC PowerScale F200 node, critical system information such as the node's identity, network configuration, and cluster membership must be preserved.

Key Points:

EasyRestore Utility:

EasyRestore is a utility provided by Dell EMC to restore critical node information after hardware replacements like system boards.

It automates the process of restoring the node's identity and configuration without manual intervention.

Retention of Critical Information:

Running EasyRestore ensures that the node re-integrates into the cluster with the correct settings.

It restores the node's serial number, GUID, and other essential identifiers.

Procedure After System Board Replacement:

After physically replacing the system board, the platform engineer should boot the node and run EasyRestore.

This process retrieves the necessary information from the node's backup flash storage.

Chapter on Hardware Replacement Procedures:

Describes the steps to replace a system board and the importance of running EasyRestore afterward.

Details how EasyRestore works and what information it restores.

Technical Advisories:

Emphasize that failure to run EasyRestore may result in the node not functioning correctly within the cluster.

Incorrect Options:

Option A (isi_node_restore -force) is not the correct utility for this task.

Option B (Flash the BIOS) is unnecessary as the BIOS is part of the system board.

Option C (Reinstall the PowerScale license) is not required because licensing is managed at the cluster level, not per node.
