##分析

首先，gipc服務主要是管理私網網路卡等相關伺服器，那麼結合日誌資訊判斷問題大致方向為私有網路。

其次，根據MOS查詢發現類似的文件<< Grid Infrastructure Upgrade/Install CRSD fails to start on the 2nd node with "gipchaLowerProcessNode: no valid interfaces found to node" in crsd.log (Doc ID 1280234.1)>>裡面有提到 udp_sendspace引數設定。

經過對比2個節點的資訊發現相關引數不符合oracle官方文件推介的引數設定

##處理步驟

#1 修改引數

/usr/sbin/no -po tcp_recvspace=65536
/usr/sbin/no -po tcp_sendspace=65536
/usr/sbin/no -po udp_recvspace=655360
/usr/sbin/no -po udp_sendspace=65536

#2 重啟網路服務

/etc/rc.tcpip 或者 refresh -s inetd

#3 啟動crs

#root使用者
./crsctl start crs
#crs和叢集服務正常啟動，問題解決

gipchaLowerProcessNode: no valid interfaces found to node
