When performing an EXTEND or TEST, the data set that is specified by the CAIPARM DD statement must contain proper values for the following control parameters:
Specify the name of the VMF Alias you want to use. You can use the same name as your primary VMF or a different name. The CATVMFX process creates the catalog entry for this alias when necessary.
Specify the name of the old VMF that is the VMF copy source. At the end of the CATVMFX EXTEND process, all TLMSs switch from this VMF to a new VMF, and this VMF is poisoned and dropped. At the end of the CATVMFX TEST process, the old VMF remains unaffected.
Specify the name of the new VMF that is the VMF copy destination. At the end of the CATVMFX EXTEND process, all TLMSs switch to this VMF. The VMF alias points to this data set. At the end of the CATVMFX TEST process, this VMF is dropped and poisoned.
(Optional) Specify the interval in one-hundredths of a second between each copy operation. In the copy step of the EXTEND/TEST process, a specific number of blocks are copied from the primary VMF to the secondary VMF. The default is 15.
(Optional) Specify the number of blocks from the primary VMF to copy during each copy operation. The default is 2400.
(Optional) Specify a comma-separated list of TLMS CPUs to exclude from the EXTEND/TEST process. Use this parameter carefully. EXCLUDE does not prevent the specified CPUs from writing to the VMF. It only causes CATVMFX to exclude the CPUs when it issues commands and checks for responses. Use EXCLUDE for a CPU which shows as active on the verification display but is no longer connected to this VMF. If you exclude a CPU, ensure that it is excluded in the verification display.
