Storage Mirroring Ports
Both the text clients and the Storage Mirroring server use ports to communicate with each other.
Text client ports
The Storage Mirroring text clients use two ports for Storage Mirroring communications.
 netport—The text clients use this port to send commands to a Storage Mirroring server.
 unetport—The text clients use this port to listen for heartbeats sent from a Storage Mirroring server.
1. To determine the current netport setting on a Storage Mirroring text client, use the get command with the netport
option. The default port number is
1500.
2. To modify the netport setting on a Storage Mirroring text client, use the set command with the netport option. The
netport option can be any number from 1025-65535 that you want to assign to the port.
