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

Start a command session on Windows.
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
```
On the Sign On page, type the credentials that you use to connect to the server.

The Start TCP/IP TELNET (TELENET) page appears.
On the Remote system line, type the AS/400 server name, and then press <F4>.

The page displays the default time as 120 seconds.
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)
```
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)
```
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

Example
```

```
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

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