After adding new nodes to an HCP G10 system, which two actions should be performed? (Choose two.)
After adding new nodes to an HCP G10 system, the following actions should be performed:
Upgrade the new nodes' software: Ensuring that the newly added nodes are running the same software version as the existing nodes is essential for compatibility and stability within the cluster.
Run the capacity balancing service: This service redistributes data across all nodes in the cluster to ensure balanced storage utilization and optimal performance, especially after the addition of new nodes.

These steps are necessary to maintain consistency, stability, and efficient use of resources within the HCP system after scaling up by adding new nodes.
You are installing an HCP G10 and need to connect to the node using PuTTY after you have installed the OS.
What is used to forward the SSH keys?
Pageant is a PuTTY authentication agent that is used to manage SSH keys for public-key authentication. When installing an HCP G10 and needing to connect to the node using PuTTY after installing the OS, Pageant can be used to forward SSH keys, allowing for a more secure and efficient connection without requiring manual password entry each time. Pageant stores the private keys and forwards them to the SSH client when required.
Hitachi Vantara Content Platform Installation Reference:
Pageant is specifically used in environments where SSH key management is necessary, particularly in secure installations of HCP systems where multiple nodes or connections are being managed.
You are performing an online upgrade of an HCP G10 and the upgrade fails.
Which log is available to assist troubleshooting?
When performing an online upgrade of an HCP G10 and the upgrade fails, the Arc-deploy logs are the relevant logs available to assist with troubleshooting. These logs contain detailed information about the deployment and upgrade processes, including errors or issues encountered during the upgrade. Accessing these logs allows administrators to diagnose the failure and take corrective actions.

The Arc-deploy logs are essential for understanding the sequence of events and identifying the exact step or component that caused the failure during an online upgrade of the HCP G10.
Your customer wants to order an HCP G10 system with 2 PB usable capacity.
Which HCP G10 configuration is the most cost-effective solution for this customer?
The most cost-effective solution for a customer requiring 2 PB of usable capacity is HCP G10 with local storage and one S30 node (B). This configuration leverages the local storage of the G10 along with the large storage capacity provided by the S30 node, which is optimized for large-scale, cost-effective storage. The S30 node can store a significant amount of data, making it a suitable choice for achieving the required capacity with fewer nodes, reducing costs. The 'HCP G10 and S30 Configuration and Sizing Guide' provides more details on cost-effective configurations for various capacity requirements.
What is the default password for logging into the S10 or the S30 management console?
The default password for logging into the S10 or the S30 management console is 'Chang3Me!'. This default password is provided to ensure initial access to the management console, but it is strongly recommended to change this password immediately upon first login to maintain system security. Information regarding default credentials can be found in the 'Hitachi Vantara HCP S10 and S30 Management Console User Guide.'
