Hi, I have read the two documentation before i asked questions: http://docs.sun.com/app/docs/doc/820-2559 http://opensolaris.org/os/community/ha-clusters/ohac/GDS-template
the first documentation is very helpful,yet,It don't like the common developer guider. The RGM,CCR,CCM,even Cluster Transport are all related to the Whole HA system. So I think it is very difficult for us to understand the HA system of solaris , and It is hard too to improve sun solaris OS,because there are banner between sun engineer and openSolaris developers out of SUN. Am I right? Thanks -- This message posted from opensolaris.org
