● Ready-to-Start-Copy - Start copy and Cancel operations ● Copy-In-Progress state - Cancel and Pause operations ● Paused state - Cancel and Resume operations ● Ready-For-Cutover state - Cancel and Cutover operations ● Cancel-Required - Cancel operation (the agentless import has failed during the copy operation) ● Cleanup-Required state - Clean up operation ● Import-Completed state - No manual operations available NOTE: Before starting a Cancel operation after the host application has been shutdown and reconfigured to use the destination volume in PowerStore, shut down the host application and reconfigure the host application to use the source volume. Shutdown of and reconfiguring the host application to use the source volume are not required when the host application has not been shutdown and reconfigured to use the destination volume in PowerStore. 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 NOTE: Once the first volume of a CG is picked up for import, the CG state changes to In-Progress. The CG remains in that state until it reaches Ready-For-Cutover. ● Ready-For-Cutover state - Cancel and Cutover operations ● Cleanup-Required state - Cleanup operation ● Cleanup-In-Progress state - No manual operations available ● Cancel-In-Progress state - No manual operations available ● Cancel-failed - Cancel operation ● Cancel-Required - Cancel operation (the agentless import has failed during the copy operation) ● Cutover-In-Progress state - No manual operations available ● Import-Cutover-Incomplete state - Cancel and Cutover operations ● Import-Completed-With-Errors - No manual operations available ● Import-Completed - No manual operations available ● Failed - Cancel operation NOTE: Any I/O failures or network outages can cause import to fail during any of the states. Before starting a Cancel operation after the host application has been shutdown and reconfigured to use the destination volume in PowerStore, shut down the host application and reconfigure the host application to use the source volume. Shutdown of and reconfiguring the host application to use the source volume are not required if the host application has not been shutdown and reconfigured to use the destination volume in PowerStore. When a paused import session is resumed, the following occurs: ● For volumes, the import session state changes to Copy-In-Progress. For consistency groups, the state changes to InProgress. ● The copy restarts from the last copied range. NOTE: Any I/O failures or network outages can cause import to fail during any of the states. If agentless import fails due to I/O or network failures, the import session goes into Cancel-Required state. Before starting a Cancel operation after the host application has been shutdown and reconfigured to use the destination volume in PowerStore, shut down the host application and reconfigure the host application to use the source volume. Shutdown of and reconfiguring the host application to use the source volume are not required if the host application has not been shutdown and reconfigured to use the destination volume in PowerStore. Cutover workflow for agentless import You can cutover an import when the import session reaches the Ready For Cutover state. The following steps show the manual import workflow in PowerStore Manager: 1. Select the import session to cutover. 2. Select the Cutover import action to cutover to the PowerStore cluster. The volume or volume group status updates to Import Complete upon successful cutover. Import workflows 39

Ready-to-Start-Copy – Start copy and Cancel operations
Copy-In-Progress state – Cancel and Pause operations
Paused state – Cancel and Resume operations
Ready-For-Cutover state – Cancel and Cutover operations
Cancel-Required – Cancel operation (the agentless import has failed during the copy operation)
Cleanup-Required state – Clean up operation
Import-Completed state – No manual operations available
NOTE:
Before starting a Cancel operation after the host application has been shutdown and reconfigured to use the
destination volume in PowerStore, shut down the host application and reconfigure the host application to use the source
volume. Shutdown of and reconfiguring the host application to use the source volume are not required when the host
application has not been shutdown and reconfigured to use the destination volume in PowerStore.
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
NOTE:
Once the first volume of a CG is picked up for import, the CG state changes to In-Progress. The CG remains in
that state until it reaches Ready-For-Cutover.
Ready-For-Cutover state – Cancel and Cutover operations
Cleanup-Required state – Cleanup operation
Cleanup-In-Progress state – No manual operations available
Cancel-In-Progress state – No manual operations available
Cancel-failed – Cancel operation
Cancel-Required – Cancel operation (the agentless import has failed during the copy operation)
Cutover-In-Progress state – No manual operations available
Import-Cutover-Incomplete state – Cancel and Cutover operations
Import-Completed-With-Errors – No manual operations available
Import-Completed – No manual operations available
Failed – Cancel operation
NOTE:
Any I/O failures or network outages can cause import to fail during any of the states. Before starting a Cancel
operation after the host application has been shutdown and reconfigured to use the destination volume in PowerStore, shut
down the host application and reconfigure the host application to use the source volume. Shutdown of and reconfiguring
the host application to use the source volume are not required if the host application has not been shutdown and
reconfigured to use the destination volume in PowerStore.
When a paused import session is resumed, the following occurs:
For volumes, the import session state changes to Copy-In-Progress. For consistency groups, the state changes to In-
Progress.
The copy restarts from the last copied range.
NOTE:
Any I/O failures or network outages can cause import to fail during any of the states. If agentless import fails due
to I/O or network failures, the import session goes into Cancel-Required state. Before starting a Cancel operation after
the host application has been shutdown and reconfigured to use the destination volume in PowerStore, shut down the
host application and reconfigure the host application to use the source volume. Shutdown of and reconfiguring the host
application to use the source volume are not required if the host application has not been shutdown and reconfigured to use
the destination volume in PowerStore.
