I would like to know how and what procedure i should follow if i want to modify or add new settings to the device mapper defaults.

 The defaults are in hwtable.c [1].

So for example how can i modify existing compiled settings for the
2810XIV device? in case i want to add a new device and it settings, how
can it be done?

 To modify the compiled settings, you have to modify it and recompile.

To modify the runtime settings (based on the defaults), you can modify
/etc/multipath.conf (see its manpage [2] with 'man multipath.conf')= .

You can verify the the setting values used during multipath discovery
with 'multipath -v3' for example, or "multipathd -k'show c= onfig'".

Hope this might still help at this time,

I would like to know how and what procedure i should follow if i want to modify or add new settings to the device mapper defaults.

 The defaults are in hwtable.c [1].

So for example how can i modify existing compiled settings for the
2810XIV device? in case i want to add a new device and it settings, how
can it be done?

 To modify the compiled settings, you have to modify it and recompile.

To modify the runtime settings (based on the defaults), you can modify
/etc/multipath.conf (see its manpage [2] with 'man multipath.conf')= .

You can verify the the setting values used during multipath discovery
with 'multipath -v3' for example, or "multipathd -k'show c= onfig'".

Hope this might still help at this time,

It's a good idea to let them know (e.g., bug/feature report). I've worked a bit w/ Ubuntu, RHEL, and SLES. Even though the changes might eventually make downstream, some distros won't pull everything (reasonably), but only the pieces they find/know to be required or desired by users/customers -- specially on released/ stable distro versions. So, letting them know / ask for consideration usually helps. -- Mauricio Faria de Oliveira IBM Linux Technology Center
