ERROR: diskgroup was not mounted

 Hi All,

We have 2 node with such node 1 and node 2.

From both nodes we can start the cluster environment.. at present node 2 is down due to OS problem.

So i am trying to start the cluster from node 1 and started fine..

while am trying to start the database... it show me error as follows

SQL> connect sys  as sysdba
