Dell PowerStore Importing External Storage to PowerStore Guide

Agentless import of external storage to PowerStore overview

Unlike nondisruptive import, agentless import of external storage to a PowerStore cluster is independent of the operating system and the multipathing solution on the host, and the front-end connectivity between the host and the source system. Agentless import does not require the installation of host plug-in software on the host. However, you must reconfigure the host application to work with the new PowerStore volumes. Only a one-time host application downtime is required before the migration. The downtime only includes renaming or reconfiguring the host application, file systems, and datastores to the new PowerStore volumes.

Use the agentless import option to migrate the external storage to a PowerStore cluster when the operating environment running on the source system does not match the respective non-disruptive supporting import operating environment. See the related list in the Simple Support Matrix for PowerStore. Also, use the agentless import option when the source system is one of the following:

• Dell PowerMax or VMAX3 system
• Dell XtremIO X1 or XtremIO X2 system
• NetApp AFF A-Series system
• Universal system (either a legacy Dell or third-party storage system)

See the PowerStore Simple Support Matrix document for the supported types of source systems and the version of operating environment that is required for the agentless import.
