NEW QUESTION # 88
Two PowerMax arrays have been configured for replication using SRDF During a disaster recovery operation production has been transferred to the R2 devices at the target site Which operation allows the primary hosts to access the R1 devices without waiting for a data transfer to complete from the R2 devices'?

A. Update
B. Failover
C. Fallback
D. Resume

Answer: D

Explanation:
Step by Step Comprehensive Detailed Explanation:
In an SRDF (Symmetrix Remote Data Facility) disaster recovery scenario where production has been switched to the R2 devices at the target site, theResumeoperation allows the primary hosts to regain access to the R1 devices without waiting for a full data transfer from the R2 devices.
Here's how it works:
* R1 Access:The Resume operation makes the R1 devices (at the primary site) accessible to the primary hosts.
* Background Synchronization:While the hosts access and modify data on the R1 devices, SRDF continues to synchronize the changes from the R2 devices (at the target site) in the background. This ensures that the R1 devices are gradually updated with any changes that occurred on the R2 devices during the failover.
This approach minimizes downtime and allows for a quicker return to the primary site without waiting for a lengthy synchronization process to complete before granting host access.
Why other options are incorrect:
* A. Update:This operation copies changes from R2 to R1, but it doesn't necessarily grant immediate host access to R1.
* B. Fallback:This is a more comprehensive process that involves reversing replication direction and fully restoring the primary site as the production environment.
* C. Failover:This operation switches production to the R2 devices, not the R1 devices.
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 resume 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
"Resume" operation.

D. TTL setting should be changed

Answer: A

NEW QUESTION # 90
Place the steps in the correct order for performing a Non-Disruptive Migration

Answer:

Explanation:

Explanation:
* Set up the migration environment to migrate applications from the source array to the target array.
* Examine the specific storage for the applications on the source array and automatically provision equivalent storage on the target array.
* Initiate data synchronization from the source to the target and cutover to make source array paths inactive so target array services all host I/O.
* Commit the necessary changes after the source to target data synchronization is complete and all application data has been migrated to the target.
* Remove the configured array-to-array connectivity for the data migration pathway on both storage arrays.
Correct Order:
* Set up the migration environment to migrate applications from the source array to the target array.
* Why:This is the initial setup phase, where you configure the necessary settings on both the source and target arrays to enable the migration. This involves actions like:
* Verifying compatibility between the source and target arrays.
* Ensuring that the required licenses are in place (e.g., NDM license).
* Configuring network connectivity (FC or iSCSI) for data transfer between the arrays.
* Examine the specific storage for the applications on the source array and automatically provision equivalent storage on the target array.
* Why:Before migrating data, you need to ensure that the target array has the appropriate storage capacity and configuration to host the applications.
* How:NDM can often automatically provision equivalent storage on the target based on the source configuration. This includes creating storage groups, volumes, and masking views that mirror the source.
* Initiate data synchronization from the source to the target and cutover to make source array paths inactive so target array services all host I/O.
* Why:This is the core of the migration process. Data is copied from the source to the target while the application continues to run. Cutover is the final step where I/O is redirected to the target array.
* How:
* Synchronization:Data is copied in the background.
* Cutover:Once synchronization is complete, a brief cutover is performed. In a well-planned NDM, this cutover is designed to be within the I/O timeout limits of most applications.
* Commit the necessary changes after the source to target data synchronization is complete and all application data has been migrated to the target.
* Why:This step finalizes the migration and makes it permanent.
* What it involves:The migration session is acknowledged and the configuration is finalized on the target array.
* Remove the configured array-to-array connectivity for the data migration pathway on both storage arrays.
* Why:After the migration is complete, the temporary connections used for data transfer between the arrays should be removed to free up resources and maintain a clean configuration.
* What it involves:This typically means removing the FC zones or iSCSI settings that were configured specifically for the NDM process.
