# View the migration SAN WWNs

Migrations can be created from the SAN. This is achieved by the integration of Open Replicator (ORS) into the Migration user interface.

## Prerequisites

The target array must be local to the control host.

## About this task

This feature provides migration support for migration from storage systems running Enginuity OS 5876, XtremeIO, VNX, Unity, DMX, and other array vendors to a storage system running PowerMaxOS 10 (6079). The migration is minimally disruptive, that is, it requires a short application downtime.

This procedure explains how to view the list of the migration SAN WWNs.

The Migrations tabbed view has been enhanced to add a new SAN WWNs tab. This view allow you to search the SAN to find Remote WWNs to create a migration from. You can initiate a SAN Scan by launching the Scan dialog, select the desired front-end ports of the currently selected array (this finds the remote ports of the front-end ports) and scan for remote devices to populate the Remote Volumes table. The Remote Volumes table acts as a launch point for the Create migration wizard.

See Understanding migration for additional information.

## Steps

1. Select the storage system.
2. Select Data Protection > Migrations
3. Select the SAN WWN tab.

   When this tab is initially selected, there are no SAN WWNs configured. You are prompted to click Scan Dialog to launch the Scan dialog (see Scan for WWNs) in order to find WWNs.

   When there are SAN WWNs configured, the following properties display:

   If you click Show Selected Ports, the following properties display:

   Local Ports table

   - Director—The Director ID of the front-end port
   - Capacity (GB)—The port number of the front-end port

   Remote Ports table

   - Port WWN—The WWN of the remote port
   - Array ID—The ID of the remote array
   - Vendor—The vendor name of the remote array
   - Remote Director—The remote director ID (if available)
   - Remote Port—The remote port number (if available)

   If you click Hide Selected Ports, the local and remote port information is not displayed.

   Remote Volume WWNs table

   - Remote Volume WWN—The WWN of the remote LUN
   - Vendor—The vendor name of the remote array
   - Capacity (GB)—The capacity in GB of the remote volume
   - Volume—The volume name of the remote LUN
   - LUN—The LUN number of the remote LUN
   - Emulation—The emulation of the remote LUN
   - Array ID—The serial ID of the remote array
   - Thin—Indicator if the remote LUN is a thin device.
   - State—The volume state of the remote LUN

   The following controls are available:

   - Scan— Scan for WWNs
   - Create— Create migration sessions using WWNs
