After completing the prerequisites, the application host or cluster is zoned to the target array FA ports. The ports that the target devices
will be masked to is determined automatically by NDM based on where the host HBAS are zoned.
EXAMINE THE MULTIPATHING CONFIGURATION
PowerPath shows what the pathing looks like prior to the create and the host rescan. For each of the four selected volumes, there are
two paths to the source array, which are both alive, meaning that they are available for host use. There are no paths yet to the target
array.
Note: Workload Planner (WLP) is a Unisphere utility that can be used to determine the ideal target ports to use for an
NDM migration. If WLP is used, it must be run from a control host that has access to both arrays. It cannot be run from
Embedded Unisphere for VMAX.
Note: The Windows disk numbers will change in the output due to changes in the test environment.
SET UP THE ENVIRONMENT
Once the required pre-migration tasks are completed, the environment can be setup using NDM. All further steps required to setup and
perform the migrations will now be handled automatically by NDM. To start the setup, click on the Storage menu followed by
Migrations.
The Environment Setup configures the migration environment that will be required to migrate any application from the source array to
the target array. It confirms that both the source and target arrays can support the NDM operations. This includes ensuring that a
useable replication pathway for data migration is available between the source and target arrays. The setup only must be run once.
When the migration pathways are configured, any storage groups can be migrated until all migrations from the source to the target are
complete.
