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.

On an HCP G10 node with six internal drives, the recommended configuration is to createa single RAID group with a single logical volume. This setup maximizes the available storagecapacity and provides a balanced approach to data protection, performance, and management simplicity. By using a single RAID group, the HCP system can efficiently manage data redundancy and integrity across all drives.

Configuring a single RAID group with a single logical volume simplifies management and provides optimal performance and redundancy, which aligns with the best practices for setting up an HCP G10 node.

The Data At Rest Encryption (DARE) feature can only be enabled during the initial cluster configuration. This is because DARE involves setting encryption parameters and keys that must be applied uniformly across all nodes in the cluster from the very beginning. Enabling DARE post-deployment could result in inconsistent encryption states and potential data access issues. The "HCP Security and Encryption Configuration Guide" details the process for enabling DARE and emphasizes the need for configuring it at the cluster's initial setup phase.
