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 nondisruptive upgrade or a network reconfiguration is in progress.

NOTE:

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

determine cluster type can be imported.

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

1.

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

source system.

NOTE:

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

remote 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 remote system and it is expected.

2.

Select the volumes to import.

3.

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

4.

Add the information needed to discover and access the host system.

5.

Set the schedule for the import.

6.

(Optional) Assign a protection policy for the import volumes.

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 remote 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 remote 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

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

•

Queued state – Cancel operation

•

Scheduled state – Cancel operation

•

In-Progress state – Cancel operation
