EZZ0827I

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 the BACKUP.

System action
 If processing an initial profile or
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
 Do the following steps to correct
the problem:  
Make one of these changes to the statement:Correct the statement so that there is exactly one DESTIP  address
that is PREFERRED and at least one DESTIP address that is BACKUP on
the VIPADISTRIBUTE statement for distribution method of HOTSTANDBY.
Remove the PREFERRED or BACKUP parameters or both parameters,
and change the distribution method  to something other than HOTSTANDBY.

If this message was displayed as a result of a VARY TCPIP,,SYNTAXCHECK
command, issue the command again to verify that you have corrected
all syntax errors in the profile. Otherwise, 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.

User response

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.
