For a file-based import, a file mobility network and file import interface must be configured. Also, the source storage system must be added to the
PowerStore cluster before creating a file import session. As part of the file import process, the source VDM or NAS server is pre-validated whether it is ready to be imported. The basic configuration (NAS server name, file systems, production interfaces) of the source file server must not change after the file import session is created. A file import session is not allowed when either a non-disruptive upgrade or a network reconfiguration is in progress.
NOTE:Only VDMs or NAS servers that have a status of
Ready can be imported.
The following steps show the manual file-based import workflow in
PowerStore Manager:
Configure the file mobility network.
If the remote (source) system does not appear in
PowerStore Manager, add the information that is used to discover and access the source system (to establish the import connection).
Configure the file import interface.
Select the VDM or NAS server to import.
Set the schedule for the file import.
Assign a protection policy for the file import session.
NOTE:The protection policy is applied to the VDM or NAS server that contains the individual file systems.
Review the summary of the import configuration information for accuracy and completeness.
Submit the import job.
NOTE:A NAS server is created on
PowerStore Manager, and access functions are set up for the source system so that data can be copied from the source VDM or NAS server to the destination NAS server. If an import session is scheduled to start later, the
Import State is shown as
Scheduled. However, if two active import sessions (which is the maximum for active import sessions) are running, any new import sessions that are set to start are shown with an
Import State of
Queued. A maximum of ten import sessions can be scheduled or queued. However, only a maximum of eight import sessions can be scheduled or queued while two import sessions are active.
You can cut over a file import after the session state changes to
Ready For Cutover.
The states of a VDM or NAS server import and the manual operations that are allowed for those states are as follows:
Scheduled state – Cancel operation
Queued state – Cancel operation
In_Progress state – Cancel operation
Completed – No manual operations available
Pausing state – Cancel operation
Paused state – Resume and Cancel operations
Cancelling – Cancel operation
Canceled – Cancel operation
Failed – Cancel operation
When a paused file import session is resumed, the following occurs:
The state changes to In-Progress.
The copy restarts from the last copied range.
NOTE:Any I/O failures or network outages can cause a file import to fail during any of the states.
