FCWAIT z/OS DFSMSdss Storage Administration SC23-6868-01 |
|
.-FCWAIT(0,0)----------------. >>-+----------------------------+------------------------------>< '-FCWAIT(numsecs,numretries)-'
FCWAIT specifies to DFSMSdss the length of the wait in seconds, and the number of additional queries on FlashCopy® background copy completion. The combination of retry interval and maximum number of retries (numsecs times numretries) designated in the FCWAIT keyword specifies the maximum length of time for DFSMSdss to wait for an existing physical background copy to complete before either initiating FlashCopy Establish or failing the COPY FULL or COPY TRACKS operation. When FCWAIT(numsecs,numretries) is specified, DFSMSdss will check for existing background copy completion before initiating a FlashCopy attempt. If no background copy is currently in progress from the COPY source to the target, DFSMSdss will establish FlashCopy immediately. If background copy is in progress, DFSMSdss will recheck at the specified interval until the designated number of retries has been reached. If background copy remains in progress when the maximum wait time has been reached, DFSMSdss will fail the COPY FULL or COPY TRACKS operation. The default for numsecs,numretries is (0,0). In other words, when FCWAIT is not specified, or when either numsecs or numretries is 0, DFSMSdss will attempt to establish FlashCopy without waiting for active background copy to end. Note:
