7.2.1.2 ALTCPU Statement

The ALTCPU statement is optional and can be used to assign
 alternate CPUs to this ORGSYSID using the CPU-serial-number.
 The ALTCPU statement can be used to transition to a new CPU
 system by assigning the new CPU serial number to this
 ORGSYSID during a system upgrade.
 
 The ALTCPU statement has the following format:
 
 ALTCPU orgsysid CPU-model CPU-serial-number
 
 where
 
 orgsysid  - is the original system identifier specified
 --------    on a previous OPTIONS statement.
 
 CPU-model - is the processor model that is used to run
 ---------   this VM system.  It is specified as a number:
             one to four digits in length.
 
 CPU-serial-number - is the processor serial number of the
 -----------------   CPU that is used to run this VM system.
                     It is specified as a hexadecimal
                     number: one to six digits in length.
 
 The ALTCPU statement must be accompanied with the OPTIONS
 statement and only applies to monitor data.  Using
 the ALTCPU statment for account data has no effect on
 assigning ORGSYSID in account data.
 
 Refer to the previous Section 7.2.1.1 to determine the
 CPU model and CPU serial number.
 
  After the CPU model and CPU serial number are determined,
  the ALTCPU statement is coded as follows:
 
     In the example, CPU model is 2098 and the CPU serial
     number is 02AAB1 the ALTCPU statement is coded as
     follows:
 
         OPTIONS    SYSA  2098  03BFA5
         ALTCPU     SYSA  2098  02AAB1
 
         ORGSYSID          : SYSA
         CPU-model         : 2098
         CPU-serial-number : 02AAB1
 
  SYSTEM UPGRADES
  ---------------
 
  Use the ALTCPU statement to transition to a new system
  during a system upgrade when there is a requirement to
  process monitor data prior to a system upgrade and after a
  system upgrade into the same DAY080 update step.  The steps
  below can help with this transition. You can do one of the
  following (In the example below, there is an upgrade to the
  zEC12, IBM zEnterprise EC12).
 
  1. Follow the steps in the previous section, 7.2.1.1 to
     determine the CPU model number and the CPU serial number
     of the upgraded system from the monitor created after
     the upgrade.
 
  2. In our example, it was determined the new CPU model is
     2728 and the CPU serial number is 04DFC2 for the
     upgraded system.
 
       The VMCOPS OPTIONS and ALTCPU statements would be coded
       as follows:
 
         OPTIONS    SYSA  2098  03BFA5
         ALTCPU     SYSA  2728  04DFC2
 
       * CPU model and CPU serial number prior to upgrade
 
         ORGSYSID          : SYSA
         CPU-model         : 2098
         CPU-serial-number : 03BFA5
 
         CPU model and CPU serial number after upgrade in
         the ALTCPU statement
 
         ORGSYSID          : SYSA
         CPU-model         : 2728
         CPU-serial-number : 04DFC2
 
  3. After the transition has passed and all the data from the
     old system has been processed, the VMCOPS OPTIONS
     statement can be updated:
 
     Change the OPTIONS statement to include the new
     CPU model and CPU serial number, then delete
     the ALTCPU statement.
 
         OPTIONS    SYSA  2728  04DFC2
 
  Remember after any change to VMCOPS you must run VMCPGEN.
