#2789 While running rnetboot, only part of the nodes are launched

[Gong Jie]

This is POWER7 IH environment. And we have statelite configurations on all the compute nodes.

While I running "rnetboot compute", I intend to make all the compute nodes boot from network. But only part of compute nodes are launched successfully. I has to rerun rnetboot command against each node manually, to make it works.

[root@c250mgrs11-pvt ~]# rpm -qa | grep xCAT

For P7 IH, it is recommended to use rbootseq and rpower to initialize the nodes boot up, see https://sourceforge.net/apps/mediawiki/xcat/index.php?title=XCAT_Power_775_Hardware_Management fore more details. Of course, the rnetboot can be used also, but the rnetboot is much more slower than rpower, and you will have to carefully setup some tunable parameters like site.ppcmaxp, site.maxssh and so on. If the rnetboot is the only way that you can use in your cluster, you can refer to https://sourceforge.net/apps/mediawiki/xcat/index.php?title=Hints_and_Tips_for_Large_Scale_Clusters or work with xCAT team on it, I do not think this is a bug, should be some setup issues.
