Explanation
This message is issued when the status of a subchannel
that uses multipath channel (MPC) changes.
resource is
the name of the TRLE or MPC subarea line that contains the subchannel.
cua is
the subchannel address.
status is the subchannel
address status, and can be one of the following:
- DEVICE ALREADY ALLOCATED
- The subchannel is already in use.
- DEVICE NOT FOUND
- The subchannel was not found by MVS™.
- INVALID DEVICE TYPE
- The subchannel device type does not match the characteristics
of the resource value.
- INVALID QDIO PORT NUMBER
- The port number (PORTNUM) specified on the QDIO TRLE definition
exceeds the number of physical ports available on the OSA-Express3
or later CHPID.
- IQDIO CULA UNAVAILABLE
- The data subchannel for HiperSockets™ (IQDIO)
is missing the control unit logical address (CULA).
- NO PATH AVAILABLE
- There is no path available to the subchannel.
- NO STORAGE TO ALLOCATE
- There is insufficient storage available to activate the subchannel.
- NOT ADDED TO VIRTUAL NET
- An ensemble virtual network does not include this host and this
OSA-Express interface.
- NOT AN ENSEMBLE MEMBER
-
Either the central processing complex (CPC) is not configured
as a member of an ensemble, or this specific z/OS® image is not included as a member of the
ensemble because the VTAM® start
option ENSEMBLE is set to the value NO. z/OS Communications
Server will not permit connectivity to either the intraensemble data
network or the intranode management network. z/OS Communications Server denies this connectivity
by denying the activation of OSX and OSM interfaces.
- OFFLINE
- Deactivation processing has completed and MVS acknowledges that the subchannel is off line.
- OFFLINE.PENDING
- An MVS VARY OFFLINE command
is issued for a subchannel and VTAM and MVS are in the process of completing
deallocation for the subchannel.
- ONLINE
- An MVS VARY ONLINE command
is issued for a subchannel and VTAM successfully
completes activation for the subchannel.
- OPEN FOR DEVICE FAILED
- The attempt to activate the subchannel failed.
- QDIO CULA UNAVAILABLE
- The data subchannel for an OSA-Express adapter
is missing the Control Unit Logical Address (CULA).
- QDIO DEVICE NOT FOUND
- The data subchannel for an OSA-Express adapter
was not found by MVS.
- QDIO DEVICE PATH INVALID
- The subchannel for an OSE-Express adapter, or iQDIO device has
a path that is not valid, or is not online to MVS.
- QDIO DEVICE TYPE NOT OSD
- The subchannel for an OSA-Express adapter
is not of type OSD.
- QDIO DEVICE TYPE NOT OSM
- The subchannel for an OSA-Express adapter is not an OSM subchannel.
- QDIO DEVICE TYPE NOT OSX
- The subchannel for an OSA-Express adapter is not an OSX subchannel.
- QDIO INVALID SUBCHANNEL
- There was a channel subsystem call (CHSC) failure for a QDIO device.
- QDIO PNET SERVICE FAILED
- The service to access the physical network ID for the OSA-Express
adapter represented by the resource value failed.
- QDIO UCBINFO UNAVAILABLE
- The subchannel for an OSA-Express adapter
has a path that is not valid.
- REACCESSIBLE
- An INOP situation occurs and MVS deactivates
and then reactivates a subchannel without operator intervention.
System action
Operator response
Depending on the value of
status,
take the following action:
- NO PATH AVAILABLE
- Ensure that all devices are on line and have PATHs available.
- OFFLINE
- Issue an MVS VARY ONLINE
command to use this subchannel for this device.
If activation succeeded or is pending for this
resource, no further response is needed. The subchannel will be dynamically
made available to the resource when it comes online. If activation
failed, attempt reactivation after making the previously described
adjustments.
System programmer response
Depending on the value of
status,
take the following action:
- DEVICE ALREADY ALLOCATED
- Ensure that the same subchannel is not used for multiple devices.
- DEVICE NOT FOUND
- Ensure that the subchannel address indicated has been defined
to MVS.
- INVALID DEVICE TYPE
- Ensure that the subchannel address indicated was defined to MVS with a type that matches the resource value
containing this subchannel. For example, if the resource value
is a transport resource list element (TRLE) with LNCTL=MPC, ensure
that the type of the subchannel is for a channel-to-channel adapter
connection.
- INVALID QDIO PORT NUMBER
- Issue the D NET,TRL,TRLE=trlename command.
Locate message IST2263I in the display output. Ensure that the displayed
PORTNUM value does not exceed the number of physical ports available
with OSA-Express3 or later. For instance, if OSA-Express3 or later
supports 2 physical ports, the only valid PORTNUM values are 0 and
1.
- IQDIO CULA UNAVAILABLE
- Contact the IBM® Software
Support Center.
- NO STORAGE TO ALLOCATE
- A storage shortage unrelated to this device activation has occurred.
Attempt to determine the reason for the storage shortage.
- NOT ADDED TO VIRTUAL NET
- Use the network virtualization function to perform the following
steps:
- Create a virtual network.
- Add this z/OS image as
a host to that virtual network.
- Specify the OSA-Express OSX interface corresponding to the TRLE
in this message as a network interface.
- Ensure that the VLANID parameter for the TCP/IP interface that
is being activated is the VLAN ID of the virtual network that you
created.
- OPEN FOR DEVICE FAILED
- Contact the IBM Software
Support Center.
- QDIO CULA UNAVAILABLE
- Contact the IBM Software
Support Center.
- QDIO DEVICE NOT FOUND
- Ensure that the subchannel address indicated has been defined
to MVS.
- QDIO DEVICE PATH INVALID
- Ensure that the subchannels on the TRLE for an OSA-Express or HiperSockets adapter have
been correctly defined. For an OSA-Express device, the subchannels
should be type OSD, OSX, or OSM. For a HiperSockets device, the subchannels
should be type IQD. Also ensure that the failing cua has
not been redefined since the device was last activated on this system.
- QDIO DEVICE TYPE NOT OSD
- The subchannel is not connected to an OSA-Express adapter that
is configured in QDIO mode. Ensure that the READ, WRITE, and DATAPATH
subchannels that are associated with the TRLE are defined as type
OSD.
- QDIO DEVICE TYPE NOT OSM
- The subchannel is not connected to the intranode management network.
Ensure that the CHPID that is defined has an OSM channel type of OSM.
- QDIO DEVICE TYPE NOT OSX
- An OSX INTERFACE is being activated by TCP/IP, but the subchannel
address is not connected to the intraensemble data network. If the
OSXCHPID parameter is defined on the INTERFACE, ensure that the CHPID
that is defined has a channel type of OSX. If the OSXPORTNAME parameter
is defined on the INTERFACE statement, ensure that the subchannel
addresses on the TRLE that match the PORTNAME are of type OSX.
- QDIO INVALID SUBCHANNEL
- Contact the IBM Software
Support Center.
- QDIO PNET SERVICE FAILED
- Contact the IBM Software
Support Center.
- QDIO UCBINFO UNAVAILABLE
- Ensure that the specified subchannel address was defined to MVS with a type that matches the
QDIO TRLE that contains this subchannel. For example, if the subchannel
is to an OSA adapter, ensure that the subchannel type is OSD, OSX,
or OSM.
