Dell Unity™ Family VNX® Series Data Import to Unity All Flash or Hybrid, or UnityVSA™ System User Guide
VNX port requirements for data import
To import data from a VNX system to a Unity system, the Unity system should be able to access the following ports on the VNX system:
- 22, 443, and 5989 to establish import connections
- 3205 and 3260 for iSCSI-based LUN import
- 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 CIFS VDM import
NOTE: On the VNX 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 VNX and Unity systems in order for the import of FLR-enabled file systems to succeed. To import FLR-enabled file systems, if the source VNX Data Mover is not using the default port, do one of the following before creating the file import:
- If possible, change the VNX Data Mover that is configured with the DHSM service to use the default port 5080.
- If the DHSM service port change cannot be made on the VNX system, on the Unity system use the svc_nas service command to change the value of the remoteDhmsPort parameter for the imt facility to reflect the same DHSM service port as that set on the VNX. This action requires a reboot of the storage processors so that the change takes effect.
For more information related to ports on the VNX system, refer to the EMC VNX Series Security Configuration Guide for VNX. For more information related to the svc_nas service command, refer to the Unity Service Commands Technical Notes.
