To upgrade a four-node HCP G10 cluster to an eight-node cluster, the customer can use additionalG10orG11node models. The HCP platform supports the addition of both G10 and G11 nodes in the same cluster, as they are compatible with each other in terms of architecture, management, and functionality. This allows the cluster to be scaled up by adding more nodes of either model to meet growing storage and performance needs.

When expanding an HCP G10 cluster, it is crucial to use node models that are supported and compatible with the existing cluster configuration, such as G10 and G11.

For the HCP G10 SSD option:

Two SSD disks are installed at the rear of the server (A):This is correct. The SSDs in the HCP G10 server are typically installed at the rear of the server to provide fast access to critical system data, such as metadata and indexes.

Software RAID1 is used to mirror the disks (C):This statement is also correct. Software RAID1 provides mirroring of the SSD disks, ensuring redundancy and data protection in case of a disk failure. RAID1 is chosen for its simplicity and reliability in providing redundancy without requiring additional hardware. Details can be found in the "HCP G10 Hardware Configuration and Maintenance Guide."

You must run the install program as root (C):To enable encryption for data at rest on anHCP system, the installation program must be executed withrootprivileges. Running the installation as root ensures that the program has the necessary permissions to configure encryption settings and other critical system operations, such as accessing low-level disk management functions and securing data at rest.

Once enabled, encryption cannot be disabled (D):In the HCP system, once encryption is enabled for data at rest, itcannot be disabled.This is a security feature designed to ensure that sensitive data remains protected throughout its lifecycle on the platform. Disabling encryption after it has been enabled would pose significant security risks, hence the system is designed to prevent this action to maintain data integrity and security.

Other options, like the encryption key being displayed several times during installation (A) or the use of SSH to enable encryption (B), are not applicable to the HCP installation and encryption process. The encryption key is carefully protected, and SSH is not specifically required for enabling encryption.

If the pre-upgrade check procedure fails due to insufficient capacity on node 103 to perform the upgrade, the service procedure to run isFree Space On Nodes. This procedure helps to identify and clear unnecessary files or redistribute data, freeing up the required capacity on the node to proceed with the upgrade.

The "Free Space On Nodes" procedure is specifically designed to manage and optimize storage capacity across HCP nodes, ensuring that upgrades and other operations have adequate space to execute successfully.

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."
