# Cannot communicate with the remote system

## Explanation:

1. The local ServeRAID Manager has lost communication with the ServeRAID Manager on the remote system.
2. The local ServeRAID Manager has lost communication with the server on which it is installed. The ServeRAID Manager agent might fail leaving the ServeRAID Manager console available, but unable to communicate with the server.

## Action:

For explanation 1, use the following actions:

- If the ServeRAID Manager is running in network mode, use the following actions:
  1. Verify that the ServeRAID Manager agent or console is running on the remote system.
  2. Verify that the port number specified for the remote system in the "Add remote system" window matches the value on the remote system. You can verify the port number on the remote system by going to the ServeRAID Manager running on that system and doing the following:
     1. Click Agent actions Configure ServeRAID Manager agent.
     2. Click the General settings tab.
     3. Verify the value for the port number. The default port numbers for remote access are 34571-34574.
  3. Verify the following:
     1. The remote system is on.
     2. Both the local and remote systems are connected to the network.
     3. TCP/IP networking support is configured on both the local and remote systems.
     4. The host name of the remote system is defined in the Domain Name Server or a Hosts file, if you are trying to connect using a host name.
     5. The network is functioning.
- If the ServeRAID Manager is running as a plug-in to another program, use the following actions:
  1. If the connection fails but has worked before, re-initiate the ServeRAID Manager task by closing the current ServeRAID Manager window and then dragging the RAID task icon onto the appropriate system.
  2. If the connection fails and has not worked before, verify the following:
     1. The remote system is on.
     2. The program using the ServeRAID Manager agent as a plug-in is installed on the remote system.
     3. Both the local and remote systems are connected to the network.
     4. TCP/IP networking support is configured on both the local and remote systems.
     5. The network is functioning.
     Notes:
       1. If you install a program that uses the ServeRAID Manager, the ServeRAID Manager agent is installed also. The ServeRAID Manager agent is started automatically by the program using it.
       2. When using the ServeRAID Manager agent as a plug-in to another program, the ServeRAID Manager does not recognize port numbers.

For explanation 2, use the following actions:

1. Verify that the ServeRAID Manager agent or console is running on the local system. View processes or services to verify that the agent is running.
2. Restart the ServeRAID Manager console.
3. Verify that TCP/IP networking support is configured on the local system.
4. Verify that the network is functioning.
5. Restart the server.
