Instructions
By default, Unity listens on port range 10500-10531 for new data transfer sessions requests. However, different data protection software vendors might use different port ranges and they are not always customizable on the software side. In these cases, Unity can be configured to listen to a different port range. The minimum port number that is allowed is 1024 and maximum port number is 65535.
Instructions to modify port range.
Step 1) Login to Unity CLI using service user.
Step 2) List current configuration:
Step 3) Modify port range to new value:
Step 4) Confirm changes:
Note 1:
In the example, setting the value to 1024-32767 means Unity listens to incoming data transfer requests between ports 1024 and 32767. These values can be changed to any number, respecting the min(1024) an max(65535) values.
Note 2:
Remember that these ports should also be opened on the firewall.
This setting takes effect immediately.
Instructions to modify port range.
Step 1) Login to Unity CLI using service user.
Step 2) List current configuration:
spa:~/user# svc_nas ALL -param -f NDMP -info portRange
Nas01 : name = portRange facility_name = NDMP default_value = 10500-10531 current_value = 10500-10531 configured_value = param_type = global user_action = none change_effective = immediate range = * description = Port range for NDMP data/mover listening
Step 3) Modify port range to new value:
spa:~/user# svc_nas ALL -param -f NDMP -modify portRange -value 1024-32767 SPA : done SPB : done
Step 4) Confirm changes:
spa:~/user# svc_nas ALL -param -f NDMP -info portRange Nas01 : name = portRange facility_name = NDMP default_value = 10500-10531 current_value = 1024-32767 configured_value = 1024-32767 param_type = global user_action = none change_effective = immediate range = * description = Port range for NDMP data/mover listening
