Troubleshooting Connectivity Between the Commvault Proxy Server and the IBM AS/400 Server

Use this procedure when you have connectivity issues between the Commvault Proxy Server and the IBM AS/400 (IBM i) server.

You can change the timeout value of the following hosts to prevent connectivity issues:

  • The IBM i file system client
  • The Commvault proxy server
  • The IBM AS/400 (IBM i) server

Before You Begin

On the Windows client, turn on the Telnet Client feature.

Procedure

CA400 Emulation

  1. Start a command session on Windows.
  2. From the command line, start a telnet session to the IBM i file system client, by typing the following command:

    telnet IBM i File System client host name

    Where IBM i File System client host name is the IBM file system client.

    Example

    telnet client.example.com

  3. On the Sign On page, type the credentials that you use to connect to the server.

    The Start TCP/IP TELNET (TELENET) page appears.

  4. On the Remote system line, type the AS/400 server name, and then press <F4>.

    The page displays the default time as 120 seconds.

  5. Change the timeout to a value that is lower than 120. On the command line, type the following command:

    TELNET RMTSYS(IBM i File System client host name) INZWAIT(time)

    Where

    IBM i File System client host name is the IBM file system client.

    time is the timeout in seconds

    Example

    TELNET RMTSYS(client.example.com) INZWAIT(20)

  6. If you still have issues, change the timeout on the Commvault proxy server, or the AS/400 server.

    On the command line, type the following command:

    TELNET RMTSYS(proxy) INZWAIT(time)

    Where

    proxy is the proxy server

    time is the timeout in seconds

    Example

    TELNET RMTSYS(proxy.example.com) INZWAIT(20)

  7. Enter a new system request. Press Shift+ESC <KEYS> , and then on the bottom of the page type 2*immed, and then press Enter.

    After you press enter, the session is released.

    time is the timeout in seconds

  7. Example

    TELNET RMTSYS(client.example.com) INZWAIT(20)

  8. If you still have issues, change the timeout on the Commvault proxy server, and the AS/400 server.

    On the command line, type the following command:

    TELNET RMTSYS(proxy) INZWAIT(time)

    Where

    proxy is the proxy server

    time is the timeout in seconds
