EMC Dell Technologies PowerMax Operate Sample Questions (Q19-Q24):

NEW QUESTION # 19
A storage administrator is using SE 10 to query a PowerMax 2000 using symcfg list -dir and wants to seethe number of Cores that are assigned to the front-end emulations What does the storage administrator need to do?

A. Look for CPU instead of Cores as these have been rebranded to allow differentiating between virtual and physical hardware.
B. Use the-mode v9x argument for backwards compatibility as some output has been deprecated
C. Specify the full 12-digit serial number with -sidsoSE 10 understands the output relates to an older system model.
D. Use syraconf igure -version -dir as in SE 10 support for outputs specific to older systems moved to a different command.

Answer: B

Explanation:
Step by Step Comprehensive Detailed Explanation:
Solutions Enabler (SE) 10 introduces some changes to the output format of certain commands for better clarity and consistency. When querying a PowerMax 2000 (which is based on older VMAX architecture) using symcfg list -dir, you might encounter differences in the output compared to previous SE versions.
To ensure backward compatibility and see the output in the familiar format, you need to use the -mode v9x argument. This tells SE 10 to display the output in the style of SE 9.x, which is compatible with the PowerMax 2000.
Why other options are incorrect:
* B. Look for CPU instead of Cores as these have been rebranded...:While there might be terminology changes, this is not the primary reason for the output difference.
* C. Specify the full 12-digit serial number with -sid so SE 10 understands...:The serial number is not directly related to the output format.
* D. Use syraconfigure -version -dir as in SE 10 support for outputs...:The syraconfigure command is not the correct command for this purpose.
References and documents of Dell's public documentation for PowerMax Operate v.2:
* Dell Solutions Enabler 10.0.0 CLI User Guide:This guide provides detailed information about the symcfg command and its options, including the -mode argument for backward compatibility. You can find this document on the Dell Support website by searching for "Solutions Enabler CLI User Guide."

NEW QUESTION # 20
What takes place during an SRDF Restore operation?

A. Changes made to the R2 are propagated to the R1 Changes made to the R1 are discarded
B. Enables access to both the R1 and R2 devices for their hosts
C. Changes made to the R1 are propagated to the R2. Changes made to the R2 are discarded
D. Resumes normal SRDF mirroring and host access

Answer: C

Explanation:
Step by Step Comprehensive Detailed Explanation:
In SRDF (Symmetrix Remote Data Facility), a "Restore" operation is used to resynchronize the source (R1) and target (R2) devices after a situation where the target device might have been modifiedindependently. This typically occurs after a failover scenario where the target device becomes the primary and undergoes changes.
During an SRDF Restore operation:
* R2 Changes Discarded:Any changes made to the target (R2) device since the last synchronization are discarded.
* R1 Changes Propagated:The current data on the source (R1) device is copied over to the target (R2), overwriting any existing data on the target.
This effectively restores the target device to a state consistent with the source device, ensuring data integrity and consistency.
Why other options are incorrect:
* B. Resumes normal SRDF mirroring and host access:While a Restore operation can be part of the failback process, it's not the only step involved. Failback might involve additional actions like reversing replication direction and restoring host access.
* C. Changes made to the R2 are propagated to the R1. Changes made to the R1 are discarded:This describes an "Update" operation, not a "Restore."
* D. Enables access to both the R1 and R2 devices for their hosts:This describes a "Split" operation, where both devices are made accessible independently.
References and documents of Dell's public documentation for PowerMax Operate v.2:
* Dell Solutions Enabler 10.0.0 SRDF Family CLI User Guide:This guide provides detailed information about SRDF commands and operations, including the symrdf restore command. You can find this document on the Dell Support website by searching for "Solutions Enabler SRDF Family CLI User Guide."
* Dell PowerMax Family: Essentials and Best Practices Guide:This guide offers a comprehensive overview of SRDF and its functionalities, including disaster recovery scenarios and the use of the
"Restore" operation.

NEW QUESTION # 22
A customer has an existing host with two 100 GB volumes that are assigned from existing PowerMax storage.
They would like to add three additional volumes of 100 GB each and change the service level that is assigned to the storage group from Gold to Platinum to support the current application SLO requirements.

Answer:

Explanation:
See the explanation for step by step solution.
Explanation:
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
