APAR Error Description / Circumvention

-------------------------------------------------
A previous failed system configuration change may cause an
inconsisent state or result in an IPL hang. One hang was
observed at SRCC6004015.

CORRECTION FOR APAR 'MA42361' :
-------------------------------
The initialization routines are improved to tolerate the
observed failure consistently.

CIRCUMVENTION FOR APAR 'MA42361' :
----------------------------------
HMC managed system

1. Power down the LPAR
2. Save the desired processor value for dedicated processor
LPARs. Save the desired shared processing units and desired
virtual processors values for a shared processor LPAR.
3. Change the LPAR profile to the following:
- For a dedicated processor LPAR, set the desired processors
equal to the minimum processors.
- For a shared processor LPAR, set the desired shared
processing units equal to the minimum shared processing units.
Also set the desired virtual processors equal to the minimum
virtual processors.
4. Power on the LPAR
5. Apply PTF MF99005.
6. Apply PTF MF56173 (IPL required).
7. Restore system settings that were previously changed.

Non-partitioned IBM i system without an HMC console

1. In SST, choose "5. Work with system partitions"
2. In SST, choose "3. Work with partition configuration"
3. In SST, use '2=Change' option on the LPAR.
4. Save the "Number of partition processors" value.
5. Set the "Number of partition processors" equal to the minimum
processors, which can be determined from data in the same
window. Once the "Number of partition processors" value is
changed, it will be changed at IPL time. You can use F9 in the
"1=Display" option to view and toggle between current and
pending values of "Number of partition processors".
6. Power down the LPAR. Power on the LPAR to pick up the
configuration changes
7. Apply PTF MF99005.
8. Apply PTF MF56173 (IPL required).
9. Restore system settings that were previously changed.


Activation Instructions
