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
