[ewg] [Q] how to setup /etc/opensm/partitions.conf??

[Hiroyuki Sato]

Hello Richard

Thank you for your information.

Is this true??,

I read this article pp44 4.4 Subinterfaces.
This step create subinterface by hand.
http://www.mellanox.com/related-docs/prod_software/Mellanox_OFED_Linux_user_manual_1_5_1.pdf


Do you know any other documents about subinterfaces.??

I removed subinterface by hand and restart opensm.
But subinterfaces not created automatically.

Thank you for your help.
