Important Log Locations for Grid

The cfgtoollogs dir under <GRID_HOME> and $ORACLE_BASE contains other important logfiles.  Specifically for rootcrs.pl and configuration assistants like ASMCA, etc...
如果还找不到错，可把日志开到debug模式再次收集一下更好一点。

Clusterware daemon logs are all under <GRID_HOME>/log/<nodename>.  Structure under <GRID_HOME>/log/<nodename>:

alert<NODENAME>.log - look here first for most clusterware issues
