Explanation
VTAM® issues
this message when the
command failed for
nodename because
an unacceptable parameter was entered.
- If parameter is U=' (blank), a line
in a channel attached major node or a local SNA PU was defined without
a device address, and the device address was not specified with the
U operand on the VARY ACT command.
- If parameter is U=device_address,
a VARY ACT command specifying U=device_address was
entered for a line in a channel attached major node or a local SNA
PU that was not active. This error occurs when device_address does
not match the device address currently in use.
- If parameter is LOGON=controllu,
a controlling LU name was specified on the LOGON operand of
a VARY ACT command for an application. Controlling LUs are only valid
for logical units.
- If parameter is RNAME, this message
can be issued for the following reasons:
- If RNAME=nodename was specified during
activation of a communication controller, nodename is
the name of a logical unit and is therefore not valid.
- If the value specified in the RNAME parameter is
not a valid link station name, the command fails.
- If RNAME=backup was specified, VTAM was not able to process backup
link station backup.
- If the value specified in the RNAME parameter does
not match the NCP definition, the command fails.
System action
VTAM rejects
the command. Other processing continues.
Operator response
- If parameter is U=' (blank), reenter
the VARY ACT command specifying the device address on the U operand.
- If parameter is U=device_address,
and the device address is correct, deactivate the line or PU and reenter
the command.
- If parameter is LOGON=controllu,
see z/OS Communications Server: SNA Operation for information on the correct
syntax of the VARY ACT command.
- If parameter is RNAME, reenter the command
specifying a valid node name or value for parameter.
System programmer response
- If parameter is U=' (blank), you might
want to specify a default device address for the line or PU.
- Otherwise, no action is required.
