Explanation
 While trying to initialize a logical unit, APPC/MVS
received an error return code from registration services or from an
RRS service.
 In the message text:  luname
The name of the logical unit that APPC/MVS was initializing
service
The name of the registration service or RRS service that returned
the non-zero return code
retcode
The return code from the registration service

System action
 APPC/MVS activates the LU, but it can process
only conversations with a synchronization level of none or confirm.

Operator response
 Notify the system programmer.

System programmer response
 To correct the problem, follow the
response for the registration service reason code, which is described
in z/OS MVS Programming: Resource Recovery. Then,
reactivate the LU through either:  Issuing a SET command for a parmlib member with an LUDEL statement,
followed by a SET command for a parmlib member with an LUADD for this
LU;  or
Entering a VTAM® VARY INACT
command, followed by a VARY ACT command for this LU.

 If the error persists, search the problem reporting data
bases for a fix for the problem. If no fix exists, contact the IBM® Support Center.
