In the event of a SAN-attached G10 node failure, which LUN configuration will maintain access to a
given set of data LUNs?
D
Explanation:
Dynamic Multi-Pathing (DMP) is a method that ensures continuous access to data in the event of a
node failure or path failure within a SAN environment. When a SAN-attached G10 node in a Hitachi
Content Platform (HCP) fails, DMP allows for automatic rerouting of data traffic to an alternate path
without interruption. This is accomplished by creating multiple physical paths between the storage
devices and the servers, ensuring that if one path fails, another can be utilized, thereby maintaining
access to data LUNs.
Hitachi Vantara Content Platform Installation Reference:
Dynamic Multi-Pathing (DMP): In the context of HCP, DMP is critical for high availability and fault
tolerance. It enables redundancy in connectivity between nodes and storage arrays, ensuring
continuous data access and minimal service disruption in the event of hardware failure. This
technology is designed to work in SAN environments where multiple paths are configured between
storage and compute resources.
SAN-Attached G10 Node Failure: If a G10 node experiences failure, DMP comes into play by
dynamically redirecting I/O operations from the failed path to an alternative path, ensuring
uninterrupted access to data stored in the associated LUNs.
By using DMP, the system effectively prevents data loss or access interruption, which is why this
configuration is recommended for maintaining LUN access during node failures in a SAN-attached
HCP environment

HCP model, but generally, two PCIe cards are sufficient to handle both networking and storage
interfaces as described in the "HCP G10 Hardware Installation Guide."
You are installing an HCP G10 and are now setting the front-end connectivity. The customer has
provided you with IP addresses for their network for each node.
Which two actions should be performed on each node as part of the OS installation? (Choose two.)
A, C
Explanation:
When installing an HCP G10 and setting up front-end connectivity, two critical actions must be
performed on each node:
Set the BMC IP Address (A): The Baseboard Management Controller (BMC) IP address must be set to
allow for remote management and monitoring of each node. This is crucial for out-of-band
management, especially in large data center environments where physical access to servers may be
limited. Configuring the BMC IP address is typically done during the initial setup of the operating
system on the HCP node.
Set the Front-End IP Address (C): The front-end IP address, which is used for client network traffic,
must be configured as provided by the customer. This IP address allows each node to communicate
with the client network, and it is a key part of the configuration during OS installation.
These configurations are detailed in the "HCP G10 Network Configuration Guide" and the "HCP G10
Installation and Configuration Manual," which provide step-by-step procedures for setting up both
the BMC and front-end IP addresses.

What is the default password to log into the HCP G10 node BIOS?
B
Explanation:
For HCP G10 nodes, the default password to access the BIOS is set to hosyu95. This is a standard
password used for initial access to the BIOS settings, allowing administrators to configure the basic
hardware settings of the HCP node.
BIOS Access:
The BIOS is the first layer of system settings that control how the hardware operates before the
system boots into the operating system or the HCP software. Accessing the BIOS is usually necessary
during the initial setup or hardware maintenance of HCP nodes.
Security Considerations:
After initial setup, it is highly recommended to change the default BIOS password for security
reasons. Using default credentials like "hosyu95" can expose the system to potential unauthorized
access if left unchanged.
The default password is documented in the HCP G10 Installation Guides provided by Hitachi Vantara,
which emphasizes the importance of securing this access after deployment.
