After adding new nodes to an HCP G10 system, which two actions should be performed? (Choose
two.)
A, B
Explanation:
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 are setting up the BIOS.
What are two requirements when configuring in the BIOS? (Choose two.)
A, D
Explanation:
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.
Hitachi Vantara Content Platform Installation Reference:
Proper configuration in the BIOS is critical for managing and booting the HCP G10 node effectively, as
outlined in the installation instructions.
Which combination of trays allows a HCP S31 to be configured to its maximum capacity?
B
Explanation:
To configure an HCP S31 to its maximum capacity, the combination of 1 x 4U100 and 8 x 4U106 trays
is used. The 4U100 is a 4U enclosure that can hold 100 drives, while the 4U106 is another 4U
enclosure that holds 106 drives. This combination allows for the highest possible storage density and
capacity, leveraging the different tray sizes to maximize the total available storage.
Hitachi Vantara Content Platform Installation Reference:
The configuration maximizes the storage capacity supported by the HCP S31 system, as specified in
the installation and hardware configuration guidelines.
What is a requirement for a running HCP system to maintain quorum for cluster operations?
D
Explanation:
For a running HCP (Hitachi Content Platform) system to maintain quorum for cluster operations, a
majority of nodes must be operational. Specifically, this means that at least 50% of the nodes + 1
node must be available to achieve quorum. Quorum is necessary to maintain consistency, availability,
and coordination among the nodes in the cluster, ensuring that the cluster can continue operating
correctly in case of node failures. This configuration avoids split-brain scenarios where multiple parts
of the cluster operate independently.
Hitachi Vantara Content Platform Installation Reference:
The quorum requirement is designed to ensure that a majority of nodes are always participating in
cluster operations, providing a safeguard against data corruption and ensuring high availability.
You are performing a six-drive upgrade of an HCP G10 with local storage.
Which two statements are true? (Choose two.)
A, C
Explanation:
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.
A customer has an HCP system consisting of four G10 nodes and they want to expand the
configuration with another four G11 nodes.
To implement this upgrade, what is the minimum HCP software version required?
C
Explanation:
To expand an existing HCP system consisting of four G10 nodes with additional G11 nodes, the
minimum required HCP software version is Version 9.0 (C). This version introduces support for
mixed-node environments, allowing the integration of different node generations (e.g., G10 and
G11) within the same cluster. It is essential to ensure compatibility and seamless operation across
the different node types. The "HCP Software Release Notes for Version 9.0" provides detailed
information on the support for mixed-node clusters.
Which two statements are true about encryption for data at rest on an HCP system? (Choose two.)
C D
Explanation:
You must run the install program as root (C):
To enable encryption for data at rest on an HCP system, the installation program must be executed
with root privileges. 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, it cannot 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.

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?
B
Explanation:
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 maximum number of drives supported in one HCP S10 enclosure?
C
Explanation:
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.
You are preparing to perform an offline upgrade on an HCP G10 and the pre-upgrade check
procedure fails. The error message says that you do not have enough capacity on node 103 to
perform the upgrade.
Which service procedure should you run to resolve this problem?
B
Explanation:
If the pre-upgrade check procedure fails due to insufficient capacity on node 103 to perform the
upgrade, the service procedure to run is Free 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.
Your customer has tested a new HCP G10 with an S10 node and they now want to re-install the S10
node before turning it into production.
What are three requirements? (Choose three.)
ABC
Explanation:
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.
Hitachi Vantara Content Platform Installation Reference:
These steps are necessary to prepare the S10 node for reinstallation without causing disruptions to
the existing HCP G10 cluster operations.
How should the RAID group(s) and logical volume(s) be configured on an HCP G10 node with six
internal drives?
A
Explanation:
On an HCP G10 node with six internal drives, the recommended configuration is to create a single
RAID group with a single logical volume. This setup maximizes the available storage capacity 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.
Hitachi Vantara Content Platform Installation Reference:
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.
A customer is using a four-node HCP G10 cluster and they would like to upgrade to eight nodes.
Which two node models can be used to upgrade the cluster? (Choose two.)
B, C
Explanation:
To upgrade a four-node HCP G10 cluster to an eight-node cluster, the customer can use additional
G10 or G11 node 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.
Hitachi Vantara Content Platform Installation Reference:
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.
