EZZ0830I

Explanation
 Because the distribution method is HOTSTANDBY
there must be exactly one DESTIP address that is specified as PREFERRED
and at least one DESTIP address that is specified as BACKUP.  The
PREFERRED and BACKUP IP addresses must be unique.  This message was
issued because an IP address was specified as both the PREFERRED and
the BACKUP DESTIP address.

System action
If processing an initial profile or
a VARY TCPIP,,OBEYFILE command, TCP/IP continues, but the VIPADISTRIBUTE
DEFINE statement is ignored. 
This message is also
displayed as part of VARY TCPIP,,SYNTAXCHECK processing when the VARY
TCPIP,,SYNTAXCHECK command detects this error in a profile data set.
 No changes are applied to the active configuration by VARY TCPIP,,SYNTAXCHECK
processing.

Operator response
 Contact the system programmer.

System programmer response
If this message was displayed
as a result of a VARY TCPIP,,SYNTAXCHECK command, correct the error
before using the profile data set as an initial profile or as a VARY
TCPIP,,OBEYFILE profile.  Otherwise, do the following steps to correct
the problem: 
Correct the statement so that the VIPADISTRIBUTE DESTIP PREFERRED
and the BACKUP IP addresses are unique.
Issue the VARY TCPIP,,OBEYFILE command with the changed VIPADYNAMIC
block.
See the information about the VIPADYNAMIC
statement in z/OS Communications Server: IP Configuration
Reference.

Automation
This message is directed to the console.
 You can use automation to detect and respond to TCP/IP profile errors
reported during initial profile and VARY TCPIP,,OBEYFILE processing.
This message can also be displayed during VARY TCPIP,,SYNTAXCHECK
processing.  Because the VARY TCPIP,,SYNTAXCHECK command does not
affect the active configuration, you might want to adjust your automation
to ignore the configuration messages that are displayed after EZZ0061I
and before EZZ0065I.
