Boot Linux® by issuing the IPL command with a DASD
boot device. You can specify additional parameters with the IPL command.
Before you begin
You need a DASD boot device that is prepared with zipl.
Procedure
Perform these steps to start the boot process:
- Establish a CMS or CP session with the z/VM guest
virtual machine where you want to boot Linux.
- Ensure that the boot device is accessible to your z/VM guest virtual machine.
- Issue a command of this form:
#cp i <devno> clear loadparm <n> parm <kernel_parameters>
where:
- <devno>
- specifies the device number of the boot device as seen by the guest.
- loadparm <n>
- is applicable to menu configurations only. Omit this parameter if you are not working with a
menu configuration.
Configuration number 0 specifies the default configuration.
Depending on the menu configuration, omitting this option might display the menu or select the
default configuration. Specifying prompt
instead of a configuration number forces the menu to
be displayed.
When the menu is displayed, you can specify additional kernel parameters. These additional
kernel parameters are appended to the parameters you might have provided in a parameter file. The
combined parameter string must not exceed 895 bytes.
- parm <kernel_parameters>
- is an optional 64-byte string of kernel parameters to be concatenated to the end of
the existing kernel parameters that are used by your boot configuration.
