There is a one-to-one mapping between /etc/opensaf/slot_id and the node_id. Simply make sure that all your system controller nodes have lower slot_id than any of your payloads. This file is read when the node is booted. You should be able to do an in-service renumbering of your nodes - just be careful so that you never have two nodes with the same node_id at the same time.
Yes, the assumption is there in 5.1.0 as well. regards, Anders Widell On 10/11/2016 04:29 AM, Jianfeng Dong wrote: > Yes, in our product payload's node_id is lower than SC, could you please tell > us how to configure it? > > And, does this assumption exist in OpenSAF 5.1.0 as well? > > Thanks, > Jianfeng > > -----Original Message----- > From: Anders Widell [mailto:anders.wid...@ericsson.com] > Sent: Tuesday, October 11, 2016 12:55 AM > To: Jianfeng Dong <jd...@juniper.net>; Neelakanta Reddy > <reddy.neelaka...@oracle.com>; opensaf-users@lists.sourceforge.net > Subject: Re: [users] OpenSAF release 5.0.1 can not promote SC after enable > "headless cluster" feature > > There is a (probably not so well documented :-) assumption that the system > controllers are configured with a lower node_id than the payloads.
