Pass the EMC Storage Administrator D-PVM-OE-01 Questions and answers with CertsForce

We need to provision 2 TB of storage to the ESXi1 host on a PowerMax array (SID 1762) using Unisphere, in a multi-tenant environment. We'll use auto-provisioning with the following specifics:

Storage Group Name:ESXi1_SG

Port Group:(A new port group with Directors OR-1C:0 and OR-2C:0)

Volume Size:2 TB (single volume)

Other Settings:Default

Here are the step-by-step instructions, tailored for the Unisphere simulator as described in the question:

Steps:

1. Launch the Simulator and Navigate to Storage Groups

Open Unisphere for PowerMax in your web browser.

You should already be logged in to the simulator, with the PowerMax array with SID 1762.

In the left-hand navigation pane, click onStorage>Storage Groups.

2. Initiate Storage Group Creation

Click theCreatebutton (likely a plus "+" icon) in the Storage Groups section to start the Create Storage Group wizard.

3. Name the Storage Group

In the "Create Storage Group" wizard:

Storage Group Name:Enter ESXi1_SG.

Enable FAST/Service Level:Do not check this option, as we are leaving all other settings at their default.

ClickNextorContinue(the exact wording might vary).

4. Add Volumes

Ensure"Create new volumes"is selected.

Number of Volumes:Enter 1.

Volume Size:

Enter 2.

Select TB from the dropdown for the unit.

ClickNext.

5. Create the Port Group

You should now be on the "Connectivity" or "Host" step, where you will add a new port group.

Select "Create Port Group"

Port Group Name:Give the new port group a name. You can use something descriptive like "ESXi1_PG," or any name that follows your organization's naming conventions.

Select Ports:

Find and select the following Directors and ports from the list of available ports:

OR-1C:0

OR-2C:0

Note:The simulator may not allow you to highlight the exact director ports as in a production environment. It will likely display all directors and ports under the selected array. Just ensure they are selected as part of the port group.

ClickNext.

6. Add host to the Masking View

Select "Add Host"

Select "Create New Host"

Host Name:ESXi1

Initiators:You don't have specific initiators to add in this simulation, so you can skip this part or add any from the available options. This is because we are working within a simulated environment.

ClickNext

7. Review and Create

You'll be presented with a summary page that shows:

Storage Group: ESXi1_SG

Volume: 1 x 2 TB volume

Port Group: (The new port group you created with OR-1C:0 and OR-2C:0)

Host: ESXi1

Carefully review all the settings to make sure they are correct.

ClickRun NoworFinish(or similar wording) to create the storage group, volume, port group, and masking view.

8. Verification (Optional)

After the operation completes, you can verify the results:

Go back to theStorage Groupslist. You should see the ESXi1_SG storage group.

Click on ESXi1_SG to view its details. You should see the 2 TB volume and the associated host (ESXi1) and port group.

You can also navigate toHosts>Port Groupsto verify that the new port group was created correctly.

Finally, you can navigate toHosts>Masking Viewsto verify that a masking view was created correctly.

Step by Step Comprehensive Detailed Explanation:

In SRDF (Symmetrix Remote Data Facility), an "update" operation refers to a specific process where changes made on the target (R2) side are copied back to the source (R1) side. This is typically used in disaster recovery scenarios where:

Failover:A failover occurs, and the target (R2) becomes the active production site.

Data Modification:Data is modified or updated on the target (R2) while it's acting as the primary.

Update Operation:An "update" is initiated to synchronize the changes from the target (R2) back to the source (R1), ensuring that the source has the latest data.

This process is crucial for maintaining data consistency and ensuring a smooth transition back to the original production site after a failover event.

Why other options are incorrect:

A. process to retain the data on the target R2 side:This is not specific to an "update" operation. Data retention on the target is a general aspect of SRDF.

B. A process used to return to the original production site after a failover event:While an "update" is part of the failback process, it's not the entire process itself. Failback involves other steps like reversing replication direction and restoring host access.

D. A process that allows separate hosts to access the same data independently:This describes a different SRDF configuration (like Active/Active) and is not related to the "update" operation.
