We ensure we code either -- or ++ as the last 2 values in the IODF name to 
allow the finding of the IODF that has the matching token that is in HSA.

Subject: EXTERNAL: Re: Questions about IPL with package IODF

A couple of assumptions. OP has only one CEC with multiple LPARs, right? IODF 
'package' just means the (linear) VSAM cluster IODFxx, right? First off, I have 
to say that this is an unusual way to manage IODFs. We have three CECs in the 
enterprise, but we use (multiple copies of) a *single* IODF for all LPARs on 
all CECs. OTOH we own all the LPARs, so we have no motivation to hide any of 
them from any of the others.

The immediate cause of the problem seems to be this:

IEA246I LOAD   ID A1 SELECTED
IEA246I NUCLST ID 01 SELECTED
IEA519I IODF DSN = MPLX.IODF00  
<===============================================  does not match HSA
IEA520I CONFIGURATION ID = EALB    . IODF DEVICE NUMBER = 8318
IEA528I IPL IODF NAME DOES NOT MATCH IODF NAME IN HARDWARE TOKEN
MPLX.IODF01 ------> Last iodf active in dynamic activation

In other words, at IPL time, IOS is using a different IODF than the one 
dynamically activated. The (dynamically activated) IODF in HSA is IODF01, but 
the system is IPLing with IODF00. Hence the token mismatch. For IPL to work, 
several steps must be taken for a new IODF.

-- Write the IODF-derived IOCDS to one of the slots in the CEC. Our CECs have 
(forever had) 4 slots labelled A0 - A3.

-- Set the 'next active' IOCDS to match the slot containing the new IOCDS. We 
always use the same slot for IPL/POR, so that slot gets overwritten with each 
new IOCDS.

-- Use the appropriate designation in LOADxx (LOADA1 in this case) to find the 
IODF 'package' that matches HSA. If you hardcode an IODF value, that's the one 
he will use whether it matches HSA or not.

Although the OP's methodology is unusual, I don't see why it would not work as 
long as all these steps are taken.

Subject: (External):Re: Questions about IPL with package IODF

I copy the production IODF(s) to the outside system(s).  There is a hardware 
token in the HSA that must match the token in the IODF.  The OP received a 
message stating the token does not match.  This is a result of the installation 
creating a separate IODF for usage with certain LPARs.

You should have one IODF that contains each processor in your installation.  
Through the Operating System configuration you can ensure devices are 
online/offline to certain configurations.  Also you can configure CHPIDs to be 
accessible to certain LPARs only.  In this manner you can separated Control 
Units and Devices by having those resources accessible only through the 
isolated CHPIDs.

The copying of the production IODF can be accomplished through several methods.
