求助：RAC安装GI时报错

环境：RAC11.2.0.4  RHEL6.5
Remote 'AttachHome' failed on nodes: 'rac2'. Refer to '/u01/app/oraInventory/logs/installActions2015-10-11_01-30-58PM.log' for details.
It is recommended that the following command needs to be manually run on the failed nodes:
/u01/app/11.2.0/grid/oui/bin/runInstaller -attachHome -noClusterEnabled ORACLE_HOME=/u01/app/11.2.0/grid ORACLE_HOME_NAME=Ora11g_gridinfrahome1 CLUSTER_NODES=rac1,rac2 "INVENTORY_LOCATION=/u01/app/oraInventory" LOCAL_NODE=<node on which command is to be run>.
Please refer 'AttachHome' logs under central inventory of remote nodes where failure occurred for more details.

按照提示在node2上执行

/u01/app/11.2.0/grid/oui/bin/runInstaller -attachHome -noClusterEnabled ORACLE_HOME=/u01/app/11.2.0/grid ORACLE_HOME_NAME=Ora11g_gridinfrahome1 CLUSTER_NODES=rac1,rac2 "INVENTORY_LOCATION=/u01/app/oraInventory" LOCAL_NODE=rac2

bash: /u01/app/11.2.0/grid/oui/bin/runInstaller: No such file or directory

这个问题应该怎么解决呀？
