Notes:
1. On all z/OS versions, ESA/390 mode is the initial mode at IPL time; however,
during IPL z/OS switches to z/Architecture 64-bit addressing.
2. z/VM is initially in ESA/390 mode at IPL time; however, during IPL it switches to
z/Architecture mode.
3. z/VSE 4.1 is initially in ESA/390 mode at IPL time; however, during IPL it
switches to z/Architecture mode. z/VSE 4.1 supports 64-bit real addressing. It
does not support 64-bit addressing mode for user applications.
IOCDS Requirements
You must use IOCP or BUILD IOCDS with HCD to create an LPAR IOCDS. You
can specify the LP names and MIF image ID numbers in an LPAR IOCDS.
Logical Partition Identifier
The logical partition identifier (ID) is used as the third and fourth hexadecimal digits
of the operand stored by the Store CPU ID instruction for each CP in the LP. Even
though at most 60 (decimal) logical partitions can be defined, valid identifiers for
LPs are X'00' through X'3F'. The LP identifier must be unique for each active LP.
Use the Customize/Delete Activation Profiles task available from the CPC
Operational Customization Tasks list to open a reset or image profile to define the
LP identifier for an LP. The Partition identifier field is located on the General page
for the LP. (See Figure 3-20 on page 3-63).
