Method B

Start of changeUse this method if there is a time delay between stopping processors, as part of the SYSTEM RESET-NORMAL function in step one, and IPLing the stand-alone dump program.End of change

  1. Perform the SYSTEM RESET-NORMAL function on SYSA.
  2. Issue VARY XCF,SYSA,OFFLINE from another active MVS™ system in the sysplex if message IXC402D or IXC102A is not present.
  3. Reply DOWN to message IXC402D or IXC102A. Performing steps two and three immediately after doing the SYSTEM RESET will expedite sysplex recovery actions for SYSA. It allows resources that are held by SYSA to be cleaned up quickly, and enables other systems in the sysplex to continue processing.
  4. IPL the stand-alone dump program (see Running the stand-alone dump program). While this step can be done earlier, the aim of performing steps one through three is to minimize disruption to other systems in the sysplex.

After a SYSTEM RESET is performed, MVS cannot automatically ISOLATE system SYSA through SFM. Message IXC402D or IXC102A is issued after the VARY XCF,SYSA,OFFLINE command or after the XCF failure detection interval expires. You must reply DOWN to IXC402D or IXC102A before sysplex partitioning can complete.
