D-PVM-OE-01 Exam Dumps - EMC Storage Administrator Questions and Answers

Step by Step Comprehensive Detailed Explanation:

The Port Attributes page in Unisphere for PowerMax allows storage administrators to configure various settings related to the front-end ports on the storage array. One of the functions available on this page isSelect Mgt Option.

This option allows you to specify how the port is used for management purposes:

Dedicated Management Port:You can designate a port as a dedicated management port, which is used exclusively for communication with management tools like Unisphere and Solutions Enabler.  

Shared Management Port:You can configure a port to be shared for both management traffic and host I/O traffic.

This flexibility allows you to optimize port usage and segregate management traffic if needed.

Why other options are incorrect:

A. Manage Protocol:Protocol settings (like FC or iSCSI) are typically configured elsewhere in Unisphere, not on the Port Attributes page.

C. Volume Set Addressing:Volume Set Addressing is a feature related to mainframe connectivity and is not directly managed through the Port Attributes page.

D. ORS Ceiling:ORS (Open Replicator Solutions) settings are managed separately and not through the Port Attributes page.

Step by Step Comprehensive Detailed Explanation:

The syradm list -environment -offline command in Solutions Enabler is used to display information about migration environments that are currently offline.

Here's what it shows:

Controlled Environments:It lists the migration environments that are directly controlled by the host where the command is executed. These are the environments where the host acts as the primary control point for the migration.

Reachable Environments:It also lists environments that are reachable from the host executing the command. This includes environments controlled by other hosts that are connected and accessible within the SAN fabric.

This broader scope allows administrators to get a comprehensive view of offline migration environments across their managed systems.

Why other options are incorrect:

A. The environments where the application has been taken offline to perform the cutover:While offline environments might be associated with cutovers, the command shows all offline environments regardless of their specific stage in the migration process.

B. Only the environments controlled by the host from where the list command is run:It also includes reachable environments, not just those directly controlled by the host.

Step by Step Comprehensive Detailed Explanation:

Non-Disruptive Migration (NDM) in PowerMax offers different modes for migrating data between storage arrays. When migrating from a VMAX array running Enginuity 5876 to a PowerMax running PowerMaxOS 5978, theAdaptive Copymode is used.

Adaptive Copy mode is designed for migrations between different storage array platforms or microcode versions. It provides flexibility and efficiency by dynamically adjusting the migration process based on the source and target array capabilities.

Why other options are incorrect:

A. Asynchronous:This mode is typically used for SRDF replication, not NDM.

C. Pass-through:This mode is not relevant to NDM.

D. Metro-based:This mode is used for specific metro distance configurations in SRDF.
