D-PVM-OE-01 Exam Dumps - Dell PowerMax Operate v.2

You want a detailed, step-by-step guide on how to add three 100 GB volumes to an existing host and change the service level of the associated storage group from Gold to Platinum on a PowerMax array, using the Unisphere for PowerMax interface shown in the image.

Here's a comprehensive guide, broken down into manageable steps:

Phase 1: Provisioning the New Volumes

Step 1: Log in to Unisphere for PowerMax

Open your web browser and enter the URL for your Unisphere for PowerMax management interface.

Log in with your administrator credentials.

Step 2: Navigate to Storage Groups

In the left-hand navigation pane, click onStorageto expand the storage management section.

Click onStorage Groupsunder the Storage section. This will display a list of existing storage groups on your PowerMax array.

Step 3: Locate the Target Storage Group

Identify the storage group that currently contains the host's existing two 100 GB volumes.

Tip:You can find this by:

Looking at the "Hosts" tab within each storage group's details. It will list the hosts connected to that storage group.

If you know the host's name, you might be able to search for it using the Unisphere search bar (if available).

Step 4: Initiate Adding Volumes

Once you've found the correct storage group, select it by clicking on its name.

Look for a button or option related to adding volumes. The exact wording might vary slightly depending on your Unisphere version, but it could be:

"Add to Storage Group"

"+"(a plus icon, which often signifies adding something)

"Add Volumes"

Click this button to start the process of adding new volumes to the storage group.

Step 5: Configure Volume Details

A new window or panel will appear, allowing you to specify the characteristics of the new volumes.

Select "Create new volumes"

Number of Volumes:Enter 3 in the field for the number of volumes.

Capacity:Enter 100 in the field for the capacity of each volume. Make sure the unit is set to GB.

Volume Name (Optional):You can give the volumes a specific name or prefix, or you can let Unisphere auto-generate names.

Service Level:Since the final goal is to move the entire Storage Group to platinum, you can either set this to platinum now or change it for the whole group later.

Other Settings:Review any other available settings (e.g., thin provisioning, data reduction). In most cases, the default settings should be fine, but adjust them if needed based on your environment's best practices.

Step 6: Execute Volume Creation

After you've configured all the volume settings, review them carefully to make sure they are correct.

Click the button to execute the operation. This button might be labeled:

"Run Now"

"OK"

"Finish"

"Apply"

Unisphere will start creating the new volumes. This might take a few moments.

Phase 2: Changing the Storage Group's Service Level

Step 7: Navigate Back to Storage Groups

Once the volume creation is complete, go back to the list of storage groups. You can usually do this by clicking "Storage Groups" in the left-hand navigation pane again.

Step 8: Select the Target Storage Group

Find the same storage group you worked with in Phase 1 (the one containing the host's volumes).

Click on the storage group's name to open its properties.

Step 9: Modify the Service Level

Look for a setting related to the "Service Level." It might be a dropdown menu, a field you can edit, or a link to a separate settings page.

Change the Service Level fromGoldtoPlatinum.

Step 10: Save the Changes

Click the button to save the changes to the storage group's service level. This button might be labeled:

"Apply"

"Save"

"OK"

Phase 3: Host-Side Configuration

Step 11: Rescan for New Storage on the Host

The host needs to be made aware of the newly provisioned storage. The exact process for this depends on the host's operating system:

Windows:

OpenDisk Management(diskmgmt.msc).

Go toAction > Rescan Disks.

Linux:

Identify the SCSI host bus numbers (e.g., ls /sys/class/scsi_host).

Use the command echo "- - -" > /sys/class/scsi_host/hostX/scan, replacing hostX with the appropriate host bus number.

You might also be able to use tools like rescan-scsi-bus.sh.

VMware ESXi:

In the vSphere Client, select the host.

Go toConfigure > Storage Adapters.

Select the relevant storage adapter (e.g., your HBA).

ClickRescan Storage.

Step 12: Initialize, Partition and Mount (if needed):

Once the host detects the new volumes, you'll need to initialize them, create partitions, format them with a filesystem, and mount them, depending on your operating system and how you intend to use the storage. This is done using the host's operating system tools.

Phase 4: Verification and Monitoring

Step 13: Verify in Unisphere

Go back to the storage group in Unisphere and check the "Volumes" tab. You should see the three new 100 GB volumes listed along with the original two, and they should all have the "Platinum" service level.

Step 14: Verify on the Host

Confirm that the host can see and access the new volumes.

Step 15: Monitor Performance

After making these changes, monitor the performance of the storage group and the application using Unisphere's performance monitoring tools. Ensure that the Platinum service level is meeting your application's requirements

1.view old HBA WWN

2.swap out the old HBA

3.Discover the WWN

4.Use the replace action

5.Use the rename action

Step by Step Comprehensive Detailed Explanation:

Unisphere for PowerMax provides a "System > Hardware" view that offers insights into the physical components of your PowerMax storage array. On newly installed 2000 and 8000 series arrays, this view would typically show information about:

Front-end directors:These directors handle host connectivity and data transfer to and from the array. The view would likely display details about the number of front-end directors, their types, and their status.  

Back-end directors:These directors manage the connection to the physical disks (storage media) within the array. The view may show the number of back-end directors, their types, and their status.

RDF (Remote Data Facility):If the array is configured for SRDF replication, the hardware view might display information about the RDF directors or components responsible for managing remote replication.

Why other options are incorrect:

A. Capacity, performance, and protection:While these are important aspects of a PowerMax system, they are typically found in other sections of Unisphere, such as the "Dashboard" or "Storage" views.

B. Provision, protect and set host I/O limits:These are management functions accessible through Unisphere, but not typically displayed directly under the "System > Hardware" view.

D. I/O Profile, performance thresholds, and anomaly detection:These are related to performance monitoring and analysis, which are usually found in the "Performance" section of Unisphere.
