2. Identify any proposed changes to the host system’s Configuration Plan. It may be
necessary to update the RIOGEN (i.e., DMKRIO, HCPRIO) to reflect changes to the
hardware addresses.
3. Code the necessary modifications in the LIBGEN macros.
Note: Changing or deleting an ACSid or LSMid in the LIBGEN is not supported by
the HSC, except for the last LSMid defined for any ACS or the last ACS defined in
the LIBGEN.
4. Assemble the LIBGEN following the procedures in ‘‘Assemble the LIBGEN File’’ in
the HSC Installation Guide .
5. Ensure that the current primary CDS copy (as shown by the Display CDS command)
is the primary copy of the old CDS input to RECONFIG. If the CDS copies need to
be rotated into a different sequence, use the procedure described under “Reassigning
Control Data Set Names in Database Heartbeat Record” on page 60.
6. Stop execution of the HSC on all hosts except the one being used to run the
Reconfiguration utility.
7. Log on to STKACS.
8. Stop task SLSBINIT on STKACS by issuing the SCP command:
STOP taskid
This allows the SCP to remain up to run the BACKup utility. Refer to the HSC
Operator’s Guide for explanations of SCP commands.
9. Verify that SLSBINIT and class U job readers are idle by issuing on STKACS the
SCP command:
QUERY ACTIVE
10. From MAINTSTK, back up the control data set by issuing the following command:
EXEC ACS UTIL BACKUP
Wait for successful job completion.
11. Stop the SCP on the remaining VM host by issuing the following command on
STKACS:
STOPSCP
12. Issue the following command to purge the service machine’s reader on STKACS:
CP PURGE READER ALL
