Usage Notes
Responses
Privilege Class: A
Use QUERY IPLPARMS to display the initial program load (IPL) parameters
currently in CP storage that CP will use for a shutdown re-IPL or a software restart.
1. This command displays exactly what was stored in the 240-byte field in CP
storage. HCPSAL (the stand-alone loader) passes the IPL parameters to CP
and then CP places them into the 240-byte field.
You can change the IPL parameters stored in this 240-byte field:
a. When creating the Stand-Alone Program Loader using the IPLPARMS
operand of the SALIPL utility.
b. During initialization, using the panel interface of SAPL.
c. After initialization using the SET IPLPARMS command (page 1263). The
new IPL parameters you specify will then be used during the next shutdown
re-IPL or a software restart. They have no effect on the current system.
2. For a description of each of the IPL parameters and more information about
SALIPL and SAPL, see the z/VM: CP Planning and Administration book.
Response 1:
To display the parameters currently stored in the IPL record, enter the following:
query iplparms
Current IPL parameters:
FN=SYSTEM FT=CONFIG CONS=08E6 PROMPT
Ready;
This response tells you that the last time you IPLed, or used the SET IPLPARMS
command, you used four IPL parameters to:
v Define the file name of the system configuration file
v Define the file type of the system configuration file
v Specify the address of the operator console
v Indicate that you want CP to prompt you for startup parameters during the next
IPL.
CP will use the default values for all the IPL parameters that you did not specify.
Response 2:
QUERY IPLPARMS
If you did not enter any IPL parameters, you would see the following response:
query iplparms
No IPL parameters are currently defined
Ready;
