VM66878: SUPPORT FOR EQDIO MVLAG AND EQDIO VNICS

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• This APAR contains the following new functions:
  
  EQDIO vNIC Simulation
  --------------------------
  Support is provided for creating simulated EQDIO adapters (via
  DEFINE NIC or NICDEF) and coupling them to a virtual switch
  operating in QDIO ETHERNET mode.  Simulated EQDIO adapters and
  simulated QDIO adapters can coexist on the same virtual switch.
  
  EQDIO Multi-VSWITCH Link Aggregation
  ---------------------------------------------
  Support is provided for using EQDIO adapters in a Multi-VSWICH
  Link Aggregation configuration.

  ****************************************************************
  With the applicable PTFs and firmware D61C Bundle 15 applied,
  z/VM will provide support for the following:
  
  EQDIO Multi-VSWITCH Link Aggregation (MVLAG)
  - EQDIO (OSH) devices can now be used for Global (cross-LPAR)
    and IVL (cross-CEC) VSWITCHes
    - IVL support provided for either EQDIO port groups or single
      RDEV configurations.
  - Device configuration limits are the same as for QDIO MVLAG
    - 4 Global VSWITCHes in an LPAR can share a port group
    - IVL cannot use the same devices as Global VSWITCHes
  - No new or changed externals
  
  EQDIO Virtual NICs
  - New EQDIO NIC type available on the NICDEF user directory
    statement and DEFINE NIC command
  - EQDIO virtual NICs connect to a QDIO virtual switch
    - VSWITCH uplink port can be either QDIO or EQDIO
    - VSWITCH must be configured in layer 2 (ETHERNET) mode
    - EQDIO and QDIO virtual NICs can coexist on the same
      virtual switch
  - This support allows z/OS guests to connect to a virtual
    switch which uses an EQDIO uplink port
  
  Help File Updates
  - Help files associated with (but not delivered with) APAR
    VM66850 (VM Disablement and Discovery of TX) are also
    included here
