[dm-devel] a few setup/control questions

[Wim Colgate]

I'm fairly new to device-mapper/multipath io, so please bear with me,
and I hope these questions are not inane.

 

I've been able to manually setup MP configurations via
/etc/multipath.conf. For example, I blacklist all wwid's and then
blacklist_excpetion just the wwid's I wish to multipath.

 

Is there a mechanism to control blacklist & expections through the
command like tools? 

 

Does adding a device through the cli override multipath.conf? (i.e.
blacklist/exceptions)

 

In general, I'd like to be able to dynamically control MP and its
parameters, rather than manually editing the .conf file and restarting
the service.

 

Regards,

 

Wim
