During ndu pre-check, a partner found that metadata-backup is not working. In addition, metadata-backup volume components have been renamed.
How can the problem be resolved?
What unique logical identifier is recommended when determining the relationship between a virtual volume and the back-end storage array?
A customer has ordered a new VPLEX, and you are on site doing the initial installation. When creating metadata volumes for the VPLEX Local configuration, the customer asks you how much total storage is needed for the VPLEX metadata. According to EMC best practices, what is the total minimum storage needed for this configuration?
What mobility operation must be performed to defragment storage volumes?
What steps must be performed to encapsulate LUNs into virtual volumes?
When creating logging and metadata volumes, which LUN requirement applies to both?
How much distributed storage can be managed by a 20 GB logging volume?
Refer to the exhibit.
Which VPlexcli command generated this output?
Which VPLEX management interface is used for initial configuration?
What three elements are part of the VPLEX Storage View?
Refer to the exhibit.
You are preparing to perform an upgrade on an unconfigured VPLEX Metro. When you run the ndu pre-check command, it indicates that it has failed and there are no first upgraders. In your troubleshooting, you run the version -a command.
Based on the output, what is the reason for the failure?
During an installation, the physical equipment inspection reveals an ESX host used for VPLEX Witness is located in the same rack as VPLEX cluster 1 Engine.
What needs to be done?
Refer to the exhibit.
What is the module at IOM A0 used for?
Where is the wwn-seed physically located on VS2 engines?
Refer to the exhibit.
You have created a Distributed Device in a VPLEX Metro. You want to confirm the volumes before performing a mobility job within the cluster. You will be moving the device to cluster 1.
Which object will be the source for this operation?
Which command would you execute to perform basic system checks to ensure that the VPLEX cluster is working properly?
You have added a new storage array to your environment, but VPLEX, does not see it. Which VPlexcli command will display the new storage array?
Following EMC best practices, which information is required to register a VPLEX on an ESRS portal?
A customer has a database application that has multiple distributed virtual volumes. They want to ensure that in the event that one of their data centers goes offline, the virtual volumes will all be available to the surviving site.
What VPLEX option should they implement?
Following EMC best practices, what information is required to register a VPLEX on an ESRS portal?
How many management Ethernet connections exist between the management server and the engines?
Refer to the exhibit:
Which two modules are used for back-end connectivity?
Refer to the exhibit.
You have opened the VPLEX Unisphere Manager to validate the health of the system.
What is the most likely reason for the Operational Status indicator?
Refer to the exhibit.
During a short power disruption to cluster 2, director-2-1-A had failed. Power was restored after 5 minutes. In examining the output of the vault status command, you note that cluster-2's status reads "Cluster is not vaulting/unvaulting".
Why did this message appear?
What device types can be created in a VPLEX environment?
What are the four basic dm migration commands for moving extents or devices?
Refer to the exhibit.
After a power disruption of 20 seconds in a VPLEX environment, the output of the "vault status" command shows no vaulting processes. Why did this occur?
Refer to the exhibit.
What is the function of the Module in slot "A"?
A customer is moving some VMAX devices under a VPLEX Local and is using PowerPath as multipath software.
What is the SCSI product ID assigned to VPLEX volumes?
Refer to the exhibit.
You are implementing a VPLEX Metro configuration, and some BE ports are not logged into the fabric.
Which VPLEX command should be performed?
A customer has a VPLEX Metro installed. They asked you to recommend a method to non-disruptively move Virtual Volumes from a storage array at Cluster 1 to a storage array at Cluster 2. What would you recommend?
