Non-disruptive import workflow

As part of the import process, the source volume or consistency group is pre-validated whether it is ready to be imported. An

import session is not allowed when either a non-disruptive upgrade or a network reconfiguration is in progress.

NOTE:

Only source volumes and consistency groups that have a status of Ready for Import, System cannot determine

cluster type, or All hosts have not been added can be imported.

The following steps show the manual import workflow in PowerStore Manager:

1. If the source system does not appear in PowerStore Manager, add the information needed to discover and access the

source system.

NOTE:

(For importing storage from a Dell EqualLogic PS series system only) After you attempt to add a PS series

system to PowerStore, the initial data connection state will appear as No Targets Discovered. However, you can

proceed to create the import session and the state will be updated to OK after the import session moves to the In

Progress state. This behavior is only specific to a PS series system and it is expected.

2. Select the volumes or consistency groups, or both to import.

3. (Optional) Assign selected volumes to a PowerStore Volume Group.

4. Select Add hosts (Host Plugin) for non-disruptive import and add the information needed to discover and access the

host systems.

5. Set the schedule for the import.

6. (Optional) Assign a protection policy for the import sessions.

7. Review the summary of the import configuration information for accuracy and completeness.

8. Begin the import.

NOTE:

The active I/O path between the host and the source system becomes passive and the passive I/O path

between the host and the PowerStore cluster becomes active. Also, the background copy of the selected source

volumes to the associated PowerStore volumes begins as well as the forwarding of host I/O from the PowerStore

cluster to the source system.

You can cutover an import after the background copy operation is complete. After cutover, the source volume is no longer

accessible to the associated hosts and the PowerStore cluster.

The states of a single volume import and the manual operations that are allowed for those states are as follows:

● Queued state – Cancel operation

● Scheduled state – Cancel operation

● Copy-In-Progress state – Cancel and Pause operations

● Paused state – Cancel and Resume operations

● Ready-For-Cutover state – Cancel and Cutover operations

● Cleanup-Required state – Cleanup operation

● Import-Completed state – No manual operations available
