Troubleshooting Connection Problems
SWCC is a TCP/IP socket-based application. As a result, SWCC requires that
each node running a SWCC Client or Agent has access to a valid hosts file or
Domain Name Service (DNS) server. Minimally, the valid hosts file must include
the system itself and all systems running the SWCC Client and Agent.
Invalid Network Port Numbers During Installation
During the Client or Agent installation, you may experience an error if the
installation program cannot find an acceptable pair of network port numbers.
Your Client uses Windows sockets (sometimes called “network ports”) to
communicate with its Agents. The socket numbers at the Client and Agent ends
must match for network communication to occur.
In Windows NT, Windows 2000, and Windows Server 2003, the socket numbers
are assigned in the services file in the
\winnt\system32\drivers\etc
subdirectory. In UNIX-based systems, the socket numbers are assigned in the
services file in the
/etc subdirectory. In the unlikely event that you experience a
conflict with the socket numbers, you may edit the file manually.
There are two default socket numbers, one for Command Console (4998) and the
other for the HS series Client and Agent (4999). If you are installing the Client or
Agent and these numbers are already taken by another application, the installation
program prompts to warn you that you must choose another pair.
To choose another pair for the Client, open the file containing the sockets in an
ASCII editor. Choose two numbers above 1023 that are not already used in the
file, and add the following two lines:
spgui number1/tcp # StorageWorks® Command Console
spagent number2/tcp # StorageWorks® Command Console
Note that the port numbers that you choose must match the port numbers used by
all of the Clients that connect to your Agent.
