   A financial services firm is consolidating workloads from two older PowerMax arrays onto a single new PowerMax 2000. The storage team has verified that all source and target arrays run PowerMaxOS 10 and that the hosts use supported multipathing software. During the migration, the team wants to verify that data is being copied correctly without interrupting production I/O. What is the most appropriate way to monitor the NDM session?

   • AUse Unisphere for PowerMax to monitor the NDM session status and copy progress in real time.
   • BDisable the host I/O and compare the source and target device contents with a byte-level diff.
   • CRun a continuous checksum validation on the host against both the source and target LUNs.
   • DCheck the array logs after the migration completes to confirm the session finished successfully.

   Which of the following is a key feature of Non-Disruptive Migration (NDM) in PowerMaxOS 10?

   A hospital is migrating a patient-records database from a PowerMax 8500 to a PowerMax 2500. The migration must not cause any data loss, and the storage team wants to ensure that the source and target remain synchronized until the final cutover. What is the most important benefit of NDM that addresses this requirement?

   • ANDM requires the hosts to be rebooted after the cutover to ensure they are using the target LUNs.
   • BNDM keeps the source and target synchronized until the cutover, ensuring that no data is lost if the migration is aborted.
   • CNDM guarantees that the migration completes without any performance impact on the source array.
   • DNDM automatically deletes the source LUNs after the cutover to prevent accidental data duplication.

   What does 'no host impact' mean in the context of Non-Disruptive Migration (NDM)?

   • AHost applications are paused during the migration
   • BHosts are disconnected from the network during migration
   • CHosts continue to access their data without interruption during the migration
   • DHosts must be reconfigured to see the new storage

   A government agency is performing a technology refresh, replacing an aging PowerMax with a new model. The agency has strict change-management policies that require all data movements to be reversible until the final cutover. The storage team has already zoned the hosts to the new array and created the target devices. What is the most important operational consideration to ensure the migration can be rolled back if a problem occurs?

   • ADelete the source devices immediately after the NDM session reaches the cutover state.
   • BKeep the NDM session active and do not delete the source devices until the migration is fully validated.
   • CReboot the hosts after the cutover to confirm the new paths are active before validating the data.
   • DDisable the source array ports to force the hosts to use the new array immediately.
