You are installing an HCP G10 with attached storage. A VSP G1000 is used to provision the storage and is used by several applications. Which action…

When installing a Hitachi Content Platform (HCP) G10 node with a shared backend storage system like a VSP G1000, the installation program must be made aware of the shared environment. The installer includes a specific prompt asking if the storage is shared. Answering "yes" to this prompt prevents the installation script from performing potentially disruptive actions, such as clearing SCSI-3 persistent reservations, which could interrupt I/O for other applications using the same storage array. This is a critical step to ensure the integrity and availability of the other services sharing the VSP G1000.

A. Shutting down other applications is an unnecessarily disruptive action. The shared storage option in the installer is specifically designed to avoid this requirement.

B. The System Management Console (SMC) is used for managing an already installed and configured HCP system. This setting is configured during the initial installation, not post-setup via the SMC.

C. While HBA configuration is part of the setup, the awareness of a shared storage environment is a software-level setting within the HCP installation program, not a specific hardware option on the HBA itself.

Section: "Running the installation program"

Content: This guide details the interactive prompts presented during the installation script. It explicitly mentions the question: "Is the backend storage shared with other applications? (yes/no)". The documentation explains that selecting "yes" is mandatory in a shared environment to prevent the installer from clearing SCSI reservations that may be in use by other hosts. This directly supports the correct answer (D) and refutes the need to shut down applications (A).

2. Hitachi Content Platform (HCP) Best Practices and Sizing Guide (KB-50HCP001-00)

Section: "Storage Provisioning Considerations"

Content: This document discusses the implications of using shared storage. It reinforces that HCP must be configured to coexist with other applications, and that installation procedures are designed to be non-disruptive. This implicitly supports the existence of a "shared storage" flag during installation to ensure safe operation.
