Special Instructions


********************************************************************
THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED
PTF HAS ALREADY BEEN APPLIED AND ITS SPECIAL INSTRUCTION FOLLOWED,
IT IS NOT NECESSARY TO FOLLOW THAT SPECIAL INSTRUCTION AGAIN.
********************************************************************

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF MF57511 :
=================================================

If v7r1m0 MF57459 is flagged as "Superseded", and the superseding PTF
is Temp Applied, remove the defective PTF(s) and apply fixing PTF
MF57511.

If v7r1m0 MF57459 is Perm Applied, please contact IBM i Software
Support for Licensed Internal Code to assess whether you are exposed
to the IPL hang condition.  If you are not exposed, then you will need
to apply the fixing PTF MF57511.  If you are exposed, or your IPL hangs
with C6003962, you should do the following on the Management Console
(HMC/SDMC/FSM):

1) Power off the failing partition.

2) Determine the amount of memory & processor assigned to the
partition in question:

lshwres -m {managed server name} -r mem --level lpar --filter
"lpar_ids=X" -F "lpar_id,lpar_name,curr_mem"

lshwres -m {managed server name} -r proc --level lpar --filter
"lpar_ids=X"
-F "lpar_id,lpar_name,curr_proc_mode,curr_procs,curr_proc_units"

where X is the partition ID.

3) Clear processor and memory assignments with the HMC command:
chhwres -m {managed server name} -r mem -o r -q {amount of memory
identified in step 2) --id X

For Shared processor mode partitions:
chhwres -m {managed server name} -r proc -o r --procunits {amount
of processor units identified in step 2) --procs {amount of
processors (Virtual Processors) identified in step 2) --id X

For Dedicated processor mode partitions:
chhwres -m {managed server name} -r proc -o r --procs {amount
of processors (Virtual Processors) identified in step 2) --id X

where X is the partition ID.

3) Activate the partition from the desired profile.

Fixing PTF MF57511 and all of its requisites should be permanently
applied.
