Dell PowerStore 1200T EMC PowerStore Importing External Storage to PowerStore - Page 25

Importing VNX2 file systems with File Level Retention (FLR)

enabled

PowerStore appliances running operating system version 3.0 or later support both FLR-E and FLR-C. When importing an

FLR-enabled file system from a VNX2 system to a PowerStore appliance, ensure the PowerStore appliance is running operating

system version 3.0 or later.

NOTE:

PowerStore appliances running operating system version 2.1.x or earlier do not support file-based import and FLR.

Limitations related to host access and NFS datastores

When performing a VDM import of FLR-enabled file systems to PowerStore, the source VNX2 Data Mover must be running

the DHSM service for the import to succeed. Also, if the source DHSM service authentication is set to

None

, you do not need

to configure the DHSM credentials, username and password, on PowerStore for import. However, if the source DHSM service

authentication is set to either

Basic

or

Digest

, you must configure those credentials at the PowerStore appliance as part of

the import configuration. If DHSM is not already configured on the source file system, refer to the VNX2 system's Unisphere

online help or the

VNX Command Line Interface Reference for File

for information about setting up the DHSM configuration on

the source VNX2 system.

PowerStore appliances do not support FLR on NFS datastores. Therefore, VNX2 FLR-enabled file systems cannot be imported

to PowerStore as NFS datastores. They can only be imported as file system objects.

NOTE:

If the source VNX2 file system is FLR-enabled, you cannot change the destination resource from a file system to an

NFS datastore. This action is not allowed.

Port requirements for DHSM when FLR is enabled

The default DHSM service port is 5080 on both VNX2 and PowerStore appliances. However, the VNX2 Data Mover (the

physical Data Mover that hosts the VDM that is being imported) that is configured with the DHSM service can be set to a

different port than the default. This port must match on both systems in order for the import of FLR-enabled file systems to

succeed. To import FLR-enabled file systems when the source VNX2 Data Mover is using another port instead of the default, if

possible, change the VNX2 Data Mover that is configured with the DHSM service to use the default port 5080.

VNX2 port requirements for file-based data import

To import file-based data from a VNX2 system to a PowerStore cluster, PowerStore should be able to access the following

ports on the VNX2 system:

●

22, 443, and 5989 to establish import connections

●

111, 137, 138, 139, 389, 445, 464, 1020, 1021, 1234, 2049, 2400, 4647, 31491, 38914, and 49152-65535 for NFS VDM import

●

137, 138, 139, 445, and 12345 for SMB (CIFS) VDM import

NOTE:

On the VNX2 source system, the physical Data Mover that is configured with the DHSM service can be set to a

different port than the default port 5080. This port must match on both VNX2 and PowerStore in order for the import of

FLR-enabled file systems to succeed. To import FLR-enabled file systems, if the source VNX2 Data Mover is not using the

default port, If possible, change the VNX2 Data Mover that is configured with the DHSM service to use the default port

5080 before creating the file import:
