s390x Install

[Martin, Larry D]

I am trying once again to install Debian on an lpar. I have downloaded the latest wheezy and have made it to the dasd configuration.

I am now stuck in the loop where it continues to ask for a device. I was told once that this is because the list of eligible devices was too large. I thought I saw an entry on this list that said a file could be edited to get past this point.

Can someone tell me what file this might be (and also what command do I use to edit the file?).

Thanks, ...........Larry

Larry, you might try using the cio_ignore= kernel option to limit the
number of addresses the zLinux kernel looks for at boot time. You might
try something like this:

cio_ignore=all,!0.0.1150,!0.0.fd00-0.0.fd02

will ignore at boot time all devices except those at addresses 1150, and
FD00-FD02.

I would put it in the generic parameter file you use at boot time to
load the kernel and initrd files.

Thanks Dave. I just added this to "s390 Boot Parameters"[1]:

| If you boot the installer in a logical partition (LPAR) or virtual
| machine (VM) where a lot of devices are visible, you might want to
| instruct the kernel to restrict the list to a fixed set of devices. This
| is advised for the installer's boot process if a lot of disks are
| visible. The "cio_ignore" option supports both a blacklist (to only
| disallow a few devices) and a whitelist (to only allow specific
| devices):
|
| <informalexample role="example"><screen>
| # blacklist: just ignore the two devices 300 and 301
| cio_ignore=0.0.0300-0.0.0301
| # whitelist: ignore everything but 1150, FD00, FD01 and FD02
| cio_ignore=all,!0.0.1150,!0.0.fd00-0.0.fd02
| </screen></informalexample>
|
| Please note that all devices numbers' hex digits need to be specified in
| lower case. To be considered during the installer's boot process the
| above option needs to be added to <filename>parmfile.debian</filename>.

But I'm neither an English native speaker nor a documentation guy.

Kind regards

Thanks, Philipp. The text looks fine, even if you are not a native
speaker. :-)

Have a good one, too.
