Workaround/Resolution
MDT-431882
Import
When importing data from
PowerMax/VMAX remote systems to
PowerStore, not all Storage Groups of the
remote system may be discovered in
PowerStore when the volume count in
PowerMax/VMAX exceeds 2000.
None.
MDT-430742
Import
When importing data from
PowerMax/VMAX remote systems to
PowerStore, the discovery of storage
resources on a PowerMax/VMAX remote
system may fail if the remote systems have
active Symmetrix Remote Data Facility
(SRDF) sessions.
If any of the PowerMax/VMAX arrays are
in SRDF relation with active SRDF sessions,
import data from one array when both the
SRDF source and target PowerMax/VMAX
arrays are imported to the same
PowerStore cluster. Add either the source
or the target PowerMax/VMAX array to
PowerStore cluster first. Then, complete
the import and delete the first
PowerMax/VMAX array before attempting
to import data from the second array.
Contact your service provider if you need
assistance.
MDT-356233
Import
The Inband Migration Tool (IMT) “Copy
Progress Percentage” and “Estimated
Completion Time” displays an incorrect
progress of 0% on the File Imports tab of the
Import External Storage page in PowerStore
Manager.
Use the REST API command
/file_import_session/{id} to view the
current_operation_progress_percentage
and estimated_completion_timestamp for
a file import session. If needed, contact
your service provider for assistance.
MDT-295614
Import
Performing a non-disruptive import using a
Windows host plug-in may fail on a
PowerStore cluster with multiple storage
networks. If multiple storage networks are
configured, all the iSCSI portals are returned
on discovery, but iSCSI portal filtering is not
supported by PowerStore.
Use one of the following workarounds:
- If possible, remove all the storage
networks except for the storage network
on which the Windows host resides.
- Perform an agentless import.
MDT-252560
Import
Import of a volume failed with the error
"Import failed because the mirror service
could not be enabled on the Destination
volume".
Run the verify operation on the remote
system to recover data connections. Once
the remote system verify operation
completes successfully, try the import
operation again.
