IST1891I
pu DIAL FAILED - MISMATCH OF IP ADDRESS FAMILIES

Explanation

This message is the first message in a group of messages displayed when the dialing of an Enterprise Extender (HPR/IP) connection fails because the remote IP address is not in the same IP address family as the local IP address; for instance, the remote IP address is an IPv4 address and the local is an IPv6 address. If the addresses are in different family types, the Enterprise Extender connection cannot be established. A complete description of the message group follows the example.

IST1680I
  • type is either LOCAL or REMOTE to identify the IP address displayed.
  • ip_address is either the remote IP address or the local IP address. The first instance of IST1680I will display the remote IP address, and the second instance of IST1680I will display the local IP address. If ip_address is ****NA****, it means that the remote node is using IPv6 protocols but the local connection is using IPv4 protocols.
IST1891I
  • line is the name of the Enterprise Extender (HPR/IP) connection that failed.
IST1909I
  • value is the host name, owned by a target remote node, that was used to acquire the remote IP address as part of name-to-address resolution. If the host name is longer than 44 characters, then the first 44 characters are displayed as value and the remaining characters are displayed in one or more IST1911I messages.
IST1910I
  • value is the host name used to acquire the local static VIPA address used as part of the attempted route determination. If the host name is longer than 45 characters, then the first 45 characters are displayed as value and the remaining characters are displayed in one or more IST1911I messages.
IST1911I
  • value is the continuation of value on IST1909I or IST1910I. IST1911I is repeated as many times as necessary to display the entire character string.

System action

Activation of the Enterprise Extender (HPR/IP) connection failed.

Operator response

None.

System programmer response

The Enterprise Extender connection cannot activate if the local and remote IP addresses are not in the same address family. The IP addresses can be obtained from the following sources:
  • For both predefined and connection network Enterprise Extender connections, the local IP address (ip_address on the IST1680I instance with type LOCAL) is obtained from one of the following:
    • The TCP/IP stack identified on the TCPNAME start option.
    • The IPADDR start option, or the IPADDR operand on the XCA major node GROUP definition statement associated with the Enterprise Extender connection network or predefined Enterprise Extender connection used for the failed route attempt, when IST1910I is not displayed.
    • The name-to-address resolution of value on IST1910I, which represents either the value supplied as the HOSTNAME start option, or the value specified as the HOSTNAME operand on the XCA major node GROUP definition statement associated with the Enterprise Extender connection network or predefined Enterprise Extender connection used for the failed route attempt.
  • For predefined Enterprise Extender connections, the remote IP address (ip_address on the IST1680I instance with type REMOTE) is obtained from one of the following:
    • The IPADDR operand on the PATH statement, when IST1909I is not displayed.
    • The name-to-address resolution of value on IST1909I, which represents the value specified as the HOSTNAME operand on the PATH definition statement.
  • For connection network Enterprise Extender connections, the remote IP address (ip_address on the IST1680I instance with type REMOTE) is obtained from one of the following:
    • The IPv4 address provided by the remote Enterprise Extender node in the APPN Route Selection Control Vector (RSCV) describing the session route to use, when IST1909I is not displayed.
    • The name-to-address resolution of value on IST1909I, which represents the host name provided by the remote Enterprise Extender node in the APPN Route Selection Control Vector (RSCV) describing the session route to use.
Ensure that one of the following is true:
  • The local or remote address was specified correctly.
  • The correct local or remote host name, or both, have been used for name-to-address resolution.
  • For an EE Connection Network, verify that all nodes are defining identical EE Connection Network names with an IP address from the same IP address family.
