Using dynamic VIPAs
Dynamic VIPA (DVIPA) support allows:
- Dynamic movement of a VIPA from a failing TCP/IP stack to a backup stack
- Dynamic allocation of a VIPA by an application program
- Manual movement of a VIPA by deactivating or reactivating it with the VARY TCPIP,,SYSPLEX command
Dynamic VIPAs (DVIPAs) are IP addresses like all other IP addresses associated with a TCP/IP, and they appear as though they had been defined at the end of the HOME list.
Dynamic VIPAs can be either IPv4 or IPv6, and both can be configured within the same VIPADYNAMIC block. A single statement (for example, VIPADEFINE or VIPABACKUP) must contain either IPv4 addresses or IPv6 addresses, but not both. However, statements that contain IPv4 addresses can be intermixed with statements that contain IPv6 addresses within the same VIPADYNAMIC block in any manner wanted.
