When replacing a fabric interconnect in a Cisco UCS (Unified Computing System) cluster, it is important to follow a specific process to ensure that the replacement interconnect is brought into the cluster properly and that the existing configuration and services are not disrupted. The correct answer to this question is Option G: Connect the new FI-A to the management network only. Use the Full State Backup file to restore the configuration through Cisco UCS Manager GUI. Connect the Layer 1/Layer 2 cables.

Here's a detailed explanation of each step in this process:

  1. Connect the new FI-A to the management network only: Before connecting the replacement fabric interconnect (FI-A) to the existing cluster, it is important to first connect it to the management network. This allows the Cisco UCS Manager to detect the new interconnect and start the process of integrating it into the cluster.

  2. Use the Full State Backup file to restore the configuration through Cisco UCS Manager GUI: Once the replacement interconnect is connected to the management network, the next step is to restore the configuration from a Full State Backup file. This backup file contains a complete copy of the configuration from the failed interconnect, including network settings, policies, and service profiles. By restoring this configuration to the replacement interconnect, it can be brought up to date with the existing cluster and start participating in service delivery.

  3. Connect the Layer 1/Layer 2 cables: After restoring the configuration to the replacement interconnect, the final step is to connect the Layer 1/Layer 2 cables to the existing fabric interconnect (FI-B). This allows the interconnect to communicate with the other devices in the cluster and to start delivering services as part of the fabric.

It is important to note that this process assumes that the failed fabric interconnect (FI-A) was the master at the time of failure. If the failed interconnect was the subordinate, the process would be slightly different, with a different backup file used for restoring the configuration. Additionally, it is important to carefully follow the instructions provided by Cisco and to ensure that all steps are completed correctly to avoid any disruption to service.
