HCP2838W HCP2841E
System Programmer Response: Reissue the
QUERY command with the correct VLAN ID, or use the
VLAN ANY option to see all activity and corresponding
VLAN IDs.
HCP2838W Device device specified for VSWITCH
switchname {does not exist | is already
attached | is not a QDIO OSA Express
device | is offline}.
Explanation: A device specified on the RDEV operand
of the DEFINE VSWITCH or SET VSWITCH command
cannot be used to connect the virtual switch to the real
LAN segment for the reason given in the message.
System Action: When the virtual switch is connected,
one or more warning messages are issued, and system
operation continues.
When the virtual switch is connecting, the system
attempts to use one of the other devices specified by
the RDEV operand. If no devices are acceptable, an
error message is issued, and the virtual switch operates
in local mode only.
System Programmer Response: Use the SET
VSWITCH command to specify a different device
number, or correct the problem and reissue the QUERY
VSWITCH command. If the display shows a VDEV next
to the failing device, the problem has been corrected
and the device is now available and initialized. If no
VDEV shows in the display for that device, issue the
SET VSWITCH switchname CONNECT command to
refresh the device or obtain a further message about a
problem with the device.
HCP2839E Invalid operand for specified
VSWITCH: operand.
Explanation: A request to update a virtual switch
cannot complete because the operand is invalid for the
specified VSWITCH. For example, PRIROUTER cannot
be specified for a VSWITCH of type ETHERNET.
System Action: System operation continues.
User Response: Reissue the command with a valid
operand.
HCP2840E The variations of this message are
listed below.
MESSAGES:
v Error ’errcode’X removing MAC address for
VSWITCH SYSTEM switchmn
v Error ’errcode’X adding MAC address for
VSWITCH SYSTEM switchmn (MAC address is
already registered.|Adapter MAC address table is
full.)
Explanation: The TCP/IP Controller received an error
when attempting to add or remove a MAC address in
the adapter’s MAC address table.
320 z/VM: System Messages and Codes — CP
v For the message format containing MAC address is
already registered, a MAC address was provided by
a guest host which has coupled to the named virtual
switch. However, that MAC address was already in
use by another guest host coupled to the virtual
switch.
v For the message format containing Adapter MAC
address table is full, the guest hosts coupled to the
virtual switch have together used more MAC
addresses than allowed by the adapter.
v For remaining message formats, an unexpected error
was received.
System Action: System operation continues, but the
MAC address table was not changed.
User Response:
v For the message format containing MAC address is
already registered, verify the MAC address
assignments for the guest hosts connected to the
Virtual Switch. Use the Query VSWITCH DETAILS
command to display the MAC address assignments
for the Virtual Switch, paying particular attention to
those marked Local or Disabled. Use the QUERY
VMLAN command to ensure the MACPREFIX is
unique across systems that are connected with the
virtual switch.
v For the message format containing Adapter MAC
address table is full, examine the MAC address
assignments for the guest hosts and remove any that
are not required. If that is not possible, create an
additional virtual switch with a separate connection to
the real hardware LAN segment.
v For remaining message formats, contact the IBM
Support Center.
HCP2841E The variations of this message are
listed below.
MESSAGES:
v Error ’errcode’X adding group MAC address
macaddr for VSWITCH SYSTEM switchmn
v Error ’errcode’X adding group MAC address
macaddr for VSWITCH SYSTEM switchmn GROUP
MAC table is full.
v Error ’errcode’X removing group MAC address
macaddr for VSWITCH SYSTEM switchmn
Explanation: The TCP/IP Controller received an error
when attempting to add or remove a multicast IP
address in the adapter’s IP multicast address table.
v For the message format containing group MAC table
is full, the guest hosts coupled to the virtual switch
have together used more MAC addresses than
allowed by the adapter.
v For remaining message formats, an unexpected error
was received.
System Action: System operation continues, but the
MAC address table was not changed.
