Overview and requirements
7 Data Migration from Dell PS Series or PowerVault MD3 to Dell EMC SC Series Storage using Thin Import | 3041-BP-EM
2.3 MD3 array requirements
To import data from an MD3 array, the SCOS version must be 7.2 or higher. Supported MD3 models and
firmware requirements are detailed in the following table:
Model
Minimum firmware version
MD32xxi
08.20.21.61
MD36xxi
08.20.21.61
MD36xxf
08.20.21.61
MD38xxi
08.25.09.61
MD38xxf
08.25.09.61
Note: When importing from MD3 iSCSI arrays to SC Series arrays, optimal import performance is achieved
when the MTU size is set to 1472 on the SC Series array.
When importing from an FC-connected MD3 array, the physical ports on the SC Series array must be zoned
to both controllers of the MD3 array. This is due to the fact that the MD3 array will only present the SC Series
array with volumes that are active on the mapped controller.
Only one remote connection per fault domain can be made to an iSCSI-connected MD3 array from an SC
Series. Unlike Fibre Channel MD3 arrays, iSCSI-connected MD3 arrays present all virtual disks over a single
connection, regardless of active controller.
Before importing data from MD3 volumes, all I/O on the volumes must be stopped and any reservations
(server mappings) on the volume should be removed.
2.4 PS Series array requirements
Note: To import data from a PS Series array, the PS Series firmware must be version 6.6 or higher. It is
highly recommended that the PS Series array is upgraded to version 9.0 or higher before importing VMware
volumes.
Before importing data from PS Series volumes, all I/O on the volumes must be stopped and any SCSI
reservations (server mappings) on the volume should be removed.
In addition to the requirements in sections 2.1 and 2.2, perform the steps in sections 2.4.1–3.3 on the PS
Series array before attempting to run the Thin Import process.
2.4.1 Configure iSCSI discovery
Note: This section only applies to PS Series arrays that have Virtual Disk Service (VDS) or Volume Shadow
Copy Service (VSS) access enabled.
When enabled, VDS/VSS access on the PS Series group creates a virtual iSCSI target that allows Windows
Server hosts to connect with and copy data to the array. VDS/VSS access is secured using a local CHAP
user on the array and requires authentication from the Dell Auto-Snapshot Manager installed on the host.
