Hi, it's not easy that all stars are aligned and five wolfs crying at the same time but all it's possible... About local fix... it's too...
OA17708: UNABLE TO IPL SYSTEMS BACK INTO A SYSPLEX, MSGIXC455D AT IPL TIME APAR status Closed as program error. KNOWN IMPACT: System(s) cannot rejoin a sysplex Local fix . BYPASS/CIRCUMVENTION: Ensure all systems are up when ACOUPLE / PSWITCH of the sysplex CDS is done. . RECOVERY ACTION: [b] IPL system with a system name not previously used in the sysplex [/b] . If that is not possible, contact L2 for further assistance. Error description When a system joins a sysplex it is given a slot number and a sequence number. The sequence number increase by one for each system that joins the sysplex. Moreover, everytime a systems joins a sysplex it is given a new sequence number. . Assume there are 2 systems in a sysplex CDS1 and CDS2 are the primary and alternate sysplex couple datasets. SY1 in slot 1 with sequence number 1 and SY2 in slot 2 with sequence number 2. Now assume SY2 is IPLd 6 times. SY2 is still in slot 2 and now has sequence number 8. Then take SY2 down. On SY1 format new sysplex couple datasets CDS3 and CDS4. Use: SETXCF COUPLE,TYPE=SYSPLEX,ACOUPLE=(CDS3) to bring in the new alternate. XCF assumes each system will update its own system record. Problem: SY2 is not active and therefore cannot update it's information. SETXCF COUPLE,TYPE=SYSPLEX,PSWITCH CDS3 is now the primary CDS SETXCF COUPLE,TYPE=SYSPLEX,ACOUPLE=(CDS4) SETXCF COUPLE TYPE=SYSPLEX,PSWITCH CDS4 is now the primary CDS. The sysplex couple dataset now reflects a high sequence number of 1! It nolonger reflects the high sequence number from SY2 or 8. When SY2 tries to IPL back into the sysplex it receives: IXC455D REPLY INTERVAL=NNN SECONDS TO RECHECK CONNECTIVITY OR R TO REINITIALIZE XCF because the sequence number on the system, SY1 is higher than the sequence number in the sysplex CDS! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
