HQT-4420 Hitachi Vantara Qualified Professional - Content Platform Installation Questions and Answers

Before re-installing the S10 node for production:

The S10 node must be retired in the HCP G10 System Management Console: This step ensures the S10 node is correctly removed from the cluster management to avoid conflicts during re-installation.

The S10 node must be disconnected from the HCP G10 cluster: Disconnecting the node from the cluster prevents any unintended interactions with the current configuration.

The S10 node must boot the installation package from the USB drive: This is required to load the new installation environment onto the S10 node, ensuring a clean and fresh installation.

These steps are necessary to prepare the S10 node for reinstallation without causing disruptions to the existing HCP G10 cluster operations.

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."

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 maximum number of drives supported in one HCP S10 enclosure is 60. The S10 enclosure is designed to accommodate a large number of drives to provide significant storage capacity in a relatively compact form factor. This drive density is essential for scaling storage in environments that require large data volumes. This configuration is detailed in the "HCP S10 Hardware Configuration Guide," which outlines the specifications and capacities of the S10 enclosures.

When setting up the BIOS for an HCP G10, two key requirements are:

The BMC (Baseboard Management Controller) IP address, net mask, and gateway should be set: This configuration enables remote management and monitoring of the HCP G10 node, allowing administrators to manage the node even when the operating system is not running.

The OS virtual disk should be selected as the boot device: This ensures that the node boots from the correct storage device where the operating system is installed, which is essential for the system to operate correctly.

Proper configuration in the BIOS is critical for managing and booting the HCP G10 node effectively, as outlined in the installation instructions.

When performing a six-drive upgrade on an HCP G10 with local storage:

RAID level and Virtual Disks will be created automatically (A):This is correct. The system automatically handles the RAID configuration and creation of virtual disks to ensure that the new drives are correctly integrated into the existing storage structure.

The node is online during this procedure (C):This is also correct. The upgrade can be performed while the node remains online, minimizing disruption to the system's operation and ensuring continuous availability. These procedures are documented in the "HCP G10 Maintenance and Upgrade Guide," which outlines the steps for online upgrades and automatic RAID configuration.

The HCP Data Protection Level setting identifies the number of copies of an object that the system maintains. This setting allows administrators to specify how many redundant copies of each object are stored across the system's nodes or storage devices, ensuring data durability and protection against hardware failures. The number of copies can be adjusted to meet the desired level of data protection according to the organization’s policy. This is explained in detail in the "HCP System Management and Configuration Guide."
