DVIPA removed record (subtype 33)
The dynamic virtual IP address (DVIPA) removed record is created when a DVIPA is removed from a TCP/IP stack. Creation of this SMF record is controlled by the following:
- DVIPA and NODVIPA parameters on the SMFCONFIG profile statement
If DVIPA is specified, the record is created and written to the SMF MVS™ data sets.
- DVIPA and NODVIPA options of the SMFSERVICE parameter on the NETMONITOR
profile statement
If DVIPA is specified, the record is created and written to the real-time TCP/IP network monitoring NMI. For more information about this NMI, see Real-time TCP/IP network monitoring NMI.
See Table 1 for the contents of the TCP/IP stack identification section. For the DVIPA removed record, the TCP/IP stack identification section indicates STACK as the subcomponent and X'08' (event record) as the record reason.

Offset | Name | Length | Type | Description |
---|---|---|---|---|
0(X'0') | SMF119DV_RmIPAddr4 | 4 | Binary | If SMF119DV_RmFlags_IPv6 is not set, this field contains the IPv4 DVIPA address. |
0(X'0') | SMF119DV_RmIPAddr6 | 16 | Binary | If SMF119DV_RmFlags_IPv6 is set, this field contains the IPv6 DVIPA address. |
16(X'10') | SMF119DV_RmFlags | 1 | Binary | Various flags:
|
17(X'11') | SMF119DV_RmOrigin | 1 | Binary | The origin of this DVIPA and how
it was configured to the stack:
|
18(X'12') | SMF119DV_RmStatus | 1 | Binary | The status of this DVIPA on the stack
before it was removed:
|
19(X'13') | SMF119DV_RmOptions | 1 | Binary | Flags indicating DVIPA options specified:
|
20(X'14') | SMF119DV_RmRank | 2 | Binary | The rank of this stack in the chain of backup stacks for this DVIPA. For entries where the SMF119DV_RmOrigin value is not SMF119DV_Orig_Backup or SMF119DV_Orig_Define, this field does not apply and is set to X'FFFF'. |
