PRERFORMING NDM OPERATIONS USING UNISPHERE
Prior to any NDM operation, the application is running in production against the source VMAX array. A VMAX All Flash, which will be
the target of the migration in this example, has been attached physically, zoned to the host, and has been discovered by Unisphere.
Figure 8. Pre-Migration with Prerequisites Completed
The All Flash, along with the source 40K, is locally attached, meaning directly connected to the host and not discovered as a remote
array via SRDF. Both arrays will appear as local arrays if the Unisphere host is directly attached to both. This is not required for NDM
operations. Only the host being migrated is required to be directly attached to both arrays.
Note: In the lab environment used here, the Solutions Enabler commands are run from the host that is being migrated.
That is acceptable for non-production environments but it is not recommended for production hosts. The SE or
Unisphere control host should be a separate management host, not a host with volumes being migrated.
