   A university IT department operates a PowerMax 8500 with two storage resource pools. One pool is heavily utilized while the other has ample free capacity. The team wants to rebalance the storage load without scheduling maintenance downtime, because the research computing cluster using the busy pool cannot be interrupted. What is the most appropriate action?

   • ATake the research cluster offline and use a storage-level copy to move the volumes.
   • BCreate a new masking view that maps the underutilized pool to the hosts and manually move the data.
   • CIncrease the size of the busy pool by adding new physical disks to the array.
   • DUse NDM to migrate selected volumes from the busy pool to the underutilized pool while the hosts remain online.

   A bank is migrating its core banking application from a PowerMax 8000 to a PowerMax 2500. The storage team has completed the NDM migration and the hosts are now running on the target array. The team wants to ensure that the source LUNs can be safely decommissioned. What should the team do before deleting the source LUNs?

   • ADelete the target LUNs first to free up space on the new array.
   • BDisable the source array ports to ensure no I/O is still going to the old array.
   • CValidate that the application is running correctly on the target array and that all data is accessible.
   • DReboot the hosts to confirm they are using the target array paths.

   A media company is migrating a video-editing storage pool from a PowerMax 8500 to a PowerMax 2500. The editing workstations are connected via Fibre Channel and use native multipathing. The migration must be transparent to the editors, meaning they should not notice any change in their mounted drives. What is the key NDM feature that ensures this transparency?

   • ANDM uses a host agent to redirect I/O to the target array without changing the device identity.
   • BNDM requires the editors to log off and log back in to refresh their drive mappings.
   • CNDM preserves the source LUN's WWN on the target, so the hosts see the same device and do not require remounting or reconfiguration.
   • DNDM requires the storage team to manually update the host's mount points after the migration.
