The following pages are under Import External Storage as shown in the following figure:
When you add the source system, you can import storage resources by selecting the source system and clicking Import Volume or Import NAS Server, depending on the resource to be imported (see Figure 18).
The following steps show the workflow of importing block resources. Once a source system is selected, click Import Volume.
The following figure shows the Import Volumes from Source Array wizard.
In the Overview step, review the description for the two types of imports and click Next.
In the Select Volumes step, select the source resources to import.
In the same step, as shown in the following figure, you can refresh the status of hosts (for non-disruptive import) and the volumes to reflect any recent changes. These changes could include the addition of new volumes in the source or the change in the mapping to the hosts.
In the Add to Volume Group (Optional) step, you can add the selected source resources into a PowerStore volume group as shown in the following figure.
In the Map Hosts step, use the Add hosts (with Host Plugin configured) for non-disruptive import option to add the clients in which the host plug-in has been installed and configured.
When adding the clients as host, you must provide the client IP address, the port that was configured to be used for the import, and the operating system (OS) type.
When the hosts are added, the system verifies the mapping of the hosts to the selected source resources, as shown in the following figure.
In the Map Hosts step, with the Map to hosts on PowerStore for agentless import option you can map the resources to be imported to hosts already added to the PowerStore.
In the Set Import Schedule step (Figure 27), you can choose to start the import immediately or at a specific date and time, or you can choose automatic cutover.
In the Assign Protection Policy step (Figure 28), you can apply a protection policy to the storage resource once it is in PowerStore.
The Review step shows a summary of all the options that are selected and provides the option to view the assigned policies in the source system.
The Source Array Assigned Policies tab shows the source system’s protection policies applied on the resources that are to be imported. The protection policies shown would not be imported but the user can export them as a CSV or XLSX file for reference as shown below.
When a storage resource is set to be imported, click the Begin Import, as shown in Figure 30, to create an import session. The import session enables managing and monitoring the life cycle of the import.
The following table shows the actions that are allowed in an import session. Actions are enabled depending on their current state.
Action | Description |
Cancel |
|
Cutover |
Note: After a cutover has been completed, it cannot be canceled and it is not possible to revert to the source resource. |
Pause |
|
Resume
|
|
Cleanup |
|
Actions applicable to agentless import | |
Enable Destination Volume | Note: Before you select this action, ensure the host application accessing the source volume or volumes is shut down. Also, ensure the host mappings are removed from the volume or volumes in the source system.
For each import session that is in the Ready To Enable Destination Volume state, select the import session, and select Import Actions > Enable Destination Volume to progress each import session to the Ready to Start Copy state. |
Start Copy | Note: Ensure the host application is reconfigured to access and use the destination volume or volumes in PowerStore.
For each import session that is in the Ready to Start Copy state, select the import session, and select Import Actions > Start Copy to progress each import session to the Copy In Progress state |
When an import session is in the state Copy In Progress, click the State column to view more details about the import session.
Click Copy In Progress in the Import State column to see the details, as shown in the following figure. The details window shows the import progress and lists the percentages of the completed data and remaining data to be imported.
The following figure shows the actions available for an import session in the Copy In Progress state.
The following steps show the workflow of importing file resources. Once a source system is selected, select the Import NAS Server button.
Figure 35 shows the Import NAS Servers from Source Array wizard.
In the Select NAS Servers step, select the source resource to import and click Next.
In the Select Migration Interface step, select the file migration interface and click Next.
In the Select Production Interface step, select the file production interface and click Assign Network Interface.
The Assign Network Interface slide out will pop up and choose the desired network interface, click Apply and click Next.
In the Configure Import step, you provide a name and description for the file import session, set when the file import will begin, and specify the interface that will be used for the import traffic.
In the Assign Protection Policy step, you can apply a protection policy to the storage resource once it is in PowerStore.
The Review step shows a summary of all the options that are selected.
Click Begin Import, which displays File Imports, where you can manage and monitor the life cycle of the file import.
The following table shows the actions that are allowed in an import session. Actions are enabled depending on their current state.
Action | Description |
Cancel |
|
Cutover | Note: Before you select this action, ensure the host application has access to the source file systems.
|
Pause |
|
Resume
|
|
Commit |
Note: After a commit has been completed, it cannot be canceled, and it is not possible to revert to the source resource. |
The following figure shows the actions available for an import session in the Ready to Cutover state.
As previously stated, you can also manage an import session from the REST API and the PowerStore CLI (pstcli). The following figure shows the different REST API queries that you can use for managing an import session from the REST API. For more details, see the document Dell PowerStore REST API Guide on Dell.com/powerstoredocs.
Imports can be managed with the PowerStoreCLI (pstcli) migration commands. For more details about the PowerStore CLI, see the document Dell PowerStore CLI Guide on Dell.com/powerstoredocs. For a list of specific migration pstcli commands run pstcli -d localhost -u admin -p password help Migration
