IST2394I

Explanation
VTAM® issues
this message when it attempts to activate an RDMA Network Interface
Card (RNIC) adapter, but the interface that this Peripheral Component
Interconnect Express® (PCIe)
function ID (PFID) value represents has been activated by a different
TCP/IP stack. Only one stack can activate an individual PFID
at a time.
In the message text:pfid_value
The PFID value that VTAM used
in the failed activation attempt.
stack_name
The TCP/IP stack that has previously activated the interface that
is associated with this PFID value.
trle_name
The name of the transport resource list entry (TRLE) that is associated
with pfid_value. VTAM automatically
generates the TRLE name when an RNIC adapter is activated.

System action
Processing continues.

Operator response
Contact the system programmer.

System programmer response
Determine which TCP/IP stack is using the incorrect PFID value. 
Correct the SMCR parameter on the GLOBALCONFIG statement in the
TCP/IP profile of the TCP/IP stack that is using the incorrect PFID
value.
Instruct the operator to first issue the VARY OBEFYFILE command
to enable the profile changes, and then to issue the VARY
START command to start the RNIC adapter.

User response
Not applicable.

Problem determination
None.
