---|---|---|
1-4 | IODF | |
10-11 | IODF
suffix. This suffix is appended to nnnnnnnn.IODF to form the name
of the nnnnnnnn.IODFxx data set. Value Range: A two-digit hexadecimal number (X'00-FF'), asterisks ('**'), pluses ('++'), minuses ('--'), or equals ('=='). If you used HCD to create your I/O Configuration data set (IOCDS), you can specify asterisks, pluses, minuses, or equals for the IODF suffix. If you specify asterisks, pluses, minuses, or equals, z/OS uses the IODF name found in the hardware configuration token. This IODF represents the last I/O configuration in the channel subsystem which you activated during the last Power® On Reset (POR) or dynamic I/O configuration change. If you override descriptor fields 1 and 2 in the HCD panel with an invalid IODF name, z/OS treats IODF suffixes '**' and '++' as if no IODF suffix was specified in LOADxx (z/OS searches from X'00' to X'FF' for a production IODF). If an invalid IODF name is found and you specified '--', z/OS searches for a production IODF starting with a suffix of X'FF'and searches backwards to X'00'. If an invalid IODF name is found and '==' were specified, z/OS loads wait state X'0B1' reason code X'00B'. |
|
If pluses ('++') are specified and a valid
IODF name is found in the hardware token, but is not found in the
search or cannot be used, IODF selection is made in the following
order:
|
||
If minuses ('--') are specified and a valid
IODF name is found in the hardware token, but is not found in the
search or cannot be used, IODF selection is made in the following
order:
|
||
Default: If not specified, all possible
IODFs (00-FF) are searched. The IODF selection is made in the following
order:
Attention: If you specify asterisks ('**'),
pluses ('++'), minuses ('--'), or equals ('==') for an IODF that does
not reside on the IODF volume, or if you omit the IODF parameter altogether,
the resulting search can substantially increase the time it takes
to IPL the system, especially if the IODF volume has a large VTOC.
In this situation, the system enters a X'073' wait state,
indicating that the IPL is waiting for an I/O interrupt. To correct
the problem, either specify the correct IODF suffix in LOADxx, or
move the required IODF to the IODF volume, then reIPL.
|
||
13-20 | High-level qualifier for the IODF data set name.
This qualifier is added to IODFxx to form the name of the nnnnnnnn.IODFxx
data set. If equals ('========') are specified, z/OS attempts to extract the high-level qualifier from the hardware configuration token. If the token is not available, a wait state is loaded. Otherwise, z/OS uses this high-level qualifier for the IODF name. If the first character of the high-level qualifier found in the hardware configuration token is blanks (' '), a wait state is loaded. Value Range: 1 to 8 alphameric characters or "========". Default: If LOADxx resides in a SYSn.IPLPARM data set, and there is no high-level qualifier specified, the high-level qualifier defaults to the high-level qualifier of the SYSn.IPLPARM data set. If LOADxx resides in a SYS1.PARMLIB data set, and there is no high-level qualifier specified, a wait state is loaded. |
|
22-29 | Operating system configuration identifier. This
eight-character identifier is used to select the appropriate configuration
from those configurations defined in the IODF. For a list of eligible
operating system configurations, select the “Define Operating
System Configurations” option on the primary HCD panel. Default: If there is only one operating system configuration identifier in nnnnnnnn.IODFxx, then that one will be used. If there is more than one identifier and the identifier is not specified, a wait state is loaded. |
|
31-32 | Eligible device table identifier Default: 00 |
|
34 | To indicate
that the system should load all of the device support modules for
the devices defined in the IODF and all the device types that support
dynamic processing, specify either Y or blank. To indicate that the
system should load only the modules required for the devices defined
in your IODF, specify any non-blank character other than Y. Default: Y |
|
36 | Subchannel set indicator. Indicates the subchannel
set IOS uses for normal base devices that have a special secondary
device with the same address. The following values can be specified:
If you are using a product to manage disk replication with HyperSwap® capability (for example, GDPS® or TPC-R), it is possible to have secondary devices attached to a subchannel set other than 0. Using such a configuration creates "special" pairs of devices consisting of one device in subchannel set 0 and a second device in an alternate subchannel set. Attaching secondary devices in an alternate subchannel set allows you to better utilize subchannel set 0 for devices that must be online and available for allocation. You must provide direction when an IPL is required so that z/OS brings the correct devices online when HyperSwap occurs (that is, when secondary devices become the devices in use, or in other words, the "active" subchannel set for a special pair of devices becomes the subchannel set to which the secondary devices are attached). On systems where special secondary devices are connected, if this value is not specified or is not valid (for example, not a 0, 1, 2, or *), the system will prompt the operator with message IEA111D to determine what subchannel set should be used. Specifying '*' allows z/OS to inherit the "active" subchannel set from the IPL devices (for IBM zEnterprise® 196 (z196) or later processors). Specifying a number indicates that a specific subchannel set is to be used as the "active" subchannel set. Consult the documentation for your disk replication manager to determine whether special pairs are supported and if any restrictions exist before specifying this parameter. Default: None |

1-8 | LPARNAME | |
10-17 | A required logical partition name as defined to LPAR. A blank entry indicates a z/OS image not running in LPAR mode. The default of matching the system being IPLed is set indirectly by specifying the HWNAME parameter. |

1-7 | MACHMIG | |
10-72 | A list of facilities not to use. When more than
one facility is listed, separate each from the previous by one or
more blanks or commas. The following facilities can be specified in
upper, lower, or mixed case:
|
*
*---+----1----+----2----+----3----+----4----+----5----+----6----+----7--
MACHMIG TX,EDAT2

1-8 | MTLSHARE | |
10 | Y indicates that the system is to run in its
coexistence mode, that is, treat MTL defined tape drives as stand-alone
drives, and do not index the cartridge loaders on such drives. N indicates that the system is to run in its full function mode. MTL defined drives are treated as MTL resident drives, and cartridge loaders on such drives are indexed per MTL rules. |
Default: N

1-7 | NUCLEUS | |
10 | A one-digit suffix that is appended to “IEANUC0”
to select a member of SYS1.NUCLEUS. Default: 1
Note: When you
specify an alternate nucleus, the proper architectural extension of
the nucleus must also exist. See page ARCHLVL
for information about architectural extensions to the nucleus.

1-6 | NUCLST | |
10-11 | A two-character suffix appended to “NUCLST”
to select a NUCLST member. Default: None |
|
13 | The character ‘Y’ indicates that
a wait state is to be loaded if any of the INCLUDE statements in the
NUCLSTxx member specify a member that cannot be found in SYS1.NUCLEUS.
If any other character is specified, the system does not load a wait
state. Note: Uppercase ‘Y’ is required. Lowercase ‘y’
indicates that a wait state is not to be loaded.
Default: Do not load a wait state. |
Column | Contents | |
---|---|---|
1-7 | PARMLIB | |
10-53 | A required valid data set name. There is no default value. | |
55-60 | A optional valid volume name. If a volume name is specified, IPL processing attempts to locate the specified data set on the specified volume. If '******' or '&SYSR1' is specified, IPL processing attempts to locate the specified data set on the system residence volume. If '*MCAT*' is specified, IPL processing attempts to locate the specified data set on the master catalog volume. If nothing is specified, IPL processing attempts to locate the specified data set first in the master catalog and, if it is not located there, on the system residence volume. |
Default: If you do not specify at least 1 PARMLIB statement, the parmlib concatenation will consist of only SYS1.PARMLIB and Master Scheduler processing will use the IEFPARM DD statement, if there is one in the Master JCL. If there are no parmlib statements in the parmlib concatenation and there is no IEFPARM DD statement, Master Scheduler processing will use SYS1.PARMLIB.

1-6 | SYSCAT | |
10-15 | The volume serial of the device that contains the master catalog.. | |
16 | The character “1”, unless SYS% to SYS1 conversion is active, in which case this will be a “2”. | |
17 | Alias name level of qualification. Value Range: 1 - 4 Default: 1 |
|
18-19 | CAS service task lower limit. Value Range: X'18' - X'B4' Default: X'3C' If you want to specify the CAS service task lower limit, specify the value with EBCDIC characters, for instance, hexadecimal B4 is specified as C'B4' or X'C2F4'. |
|
20-63 | The 44-byte data set name of the master catalog. | |
64-71 | The 1 to 8 character high-level qualifier of
the tape volume catalog. Default: SYS1 |
|
72 | Specify Y to enable AUTOADD when the catalog address space (CAS) makes the first connection to the coupling facility. The AUTOADD function enables coupling facility support of enhanced catalog sharing (ECS) for eligible catalogs. |
Default: If you do not specify a SYSCAT statement, the system prompts the operator to specify the SYSCATxx member of SYS1.NUCLEUS.
During system initialization, NIP first processes the IEASYS00 parmlib member to establish parameters. Then it determines, from the suffixes that are specified on the SYSPARM statement in LOADxx, the SYSPARM parameter in IEASYMxx, or by the operator, which IEASYSxx members are to be used. See Step 2. Determine where to specify system parameters for a description of how the system determines which IEASYSxx members are to be used.
