ib_send_bw that prevents connections to another server and thus blocks Fluid

Cache network traffic.

Possible Cause One of the ports required by Fluid Cache is in use by another process.

Solution Refer to the required ports listed in Checking Network Connections and reassign

ports as needed.

• Check which ports are in use by logging in as a root user and running this

command:

/bin/netstat -tulpn

• To change the ports used by Fluid Cache, open the /etc/services file on

each server and add the following information, modifying the port numbers as

needed:

fldc-http 8080/tcp # Fluid Cache CFM Web Server

fldc-https 6773/tcp # Fluid Cache CFM Web Server

fldca-http 8082/tcp # Fluid Cache Agent Web Server

fldca-https 6774/tcp # Fluid Cache Agent Web Server

The existing entry for the mDNS service on UDP port 5353 may also need to be

modified. It is used by the Avahi daemon, which is required by Fluid Cache.

• After changing the ports, restart the Fluid Cache agent service by running the

following command:

service fldc_agentd restart

NOTE: Port 6774 is used to communicate with Enterprise Manager. If you

change the port number for fldca-https in the etc/services file, you

must also configure Enterprise Manager to use the new port number.

NOTE: Port 3033 is used to communicate with Enterprise Manager and

Storage Center. To configure those applications to use a different port, refer to

the corresponding Administrator’s Guide. After a new port is configured in

Enterprise Manager or Storage Center, Fluid Cache automatically uses the new

port.

NOTE: Port 7449 is required by Fluid Cache. If another application is using this

port, configure that application to use a different port.

Possible Cause The network adapters are not configured for Ethernet functionality, and so the

ethtool and ifconfig commands cannot be used to configure the network

adapters.

Solution On each node in the Fluid Cache cluster, run the command:

connectx_port_config

In the configuration file, if the entry for ConnectX PCI Devices references auto or

ib, change the setting for Select mode for port x to 2.
