Css, Lpar, And Identifier Example - IBM z13s Technical Manual

An example that summarizes the definition of these LPAR-related identifications is shown in
Figure 5-4.

Figure 5-4 CSS, LPAR, and identifier example
LPAR name
The LPAR name is defined as partition name parameter in the RESOURCE statement of an I/O
configuration. The LPAR name must be unique across the server.
MIF image ID
The MIF image ID is defined as a parameter for each LPAR in the RESOURCE statement of an
I/O configuration. It ranges from 1 to F, and must be unique within an LCSS, and can be
duplicate in different LCSSs. If a MIF image ID is not defined, an arbitrarily ID is assigned
when the I/O configuration activated. The z13s server supports a maximum of three LCSSs,
with a total number of 40 LPARs that can be defined. Each LCSS of a z13s server has these
maximum number of LPARs:
LCSS0 and LCSS1 support 15 LPARs each, and MIF image ID range from 1 to F within
each LCSS.
LCSS2 supports 10 LPARs, and MIF image ID range from 1 to A.
LPAR ID
The LPAR ID is defined by user in an image activation profile for each LPAR. It is a 2-digit
heximal number from 00 to 7F. The LPAR ID must be unique across the server
arbitrary defined by user, normally an LPAR ID is the CSS ID concatenated to its MIF image
ID, which makes the value more meaningful and easy for system administration. For example,
an LPAR with LPAR ID 1A means that the LPAR is defined in LCSS1, with the MIF
image ID A.
