26.7. Miscellaneous Parameters

The following parameters can be defined in a parameter file but do not work in a CMS configuration file.
askmethod
Do not use an automatically detected DVD as installation source but ask for the installation method to manually specify the installation source. This parameter is useful if you booted from an FCP-attached DVD but want to continue with another installation source, for example on the network or on a local hard disk.
mediacheck
Turns on testing of an ISO-based installation source; for example, when booted from an FCP-attached DVD or using repo= with an ISO on local hard disk or mounted with NFS.
nompath
Disables support for multipathing devices.
proxy=[protocol://][username[:password]@]host[:port]
Specify a proxy to use with installation over HTTP, HTTPS, or FTP.
rescue
Boot into a rescue system running from a ramdisk that can be used to fix and restore an installed system.
stage2=URL
Specifies a path to an install.img file instead of to an installation source. Otherwise, follows the same syntax as repo=. If stage2 is specified, it typically takes precedence over other methods of finding install.img. However, if anaconda finds install.img on local media, the stage2 URL will be ignored.
If stage2 is not specified and install.img cannot be found locally, anaconda looks to the location given by repo= or method=.
If only stage2= is given without repo= or method=, anaconda uses whatever repos the installed system would have enabled by default for installation.
syslog=IP/hostname[:port]
Makes the installer send log messages to a remote syslog server.
The boot parameters described here are the most useful for installations and trouble shooting on System z, but only a subset of those that influence the installer. Refer to Chapter 28, Boot Options for a more complete list of installer boot parameters.
