What version of 11gr2 188.8.131.52 184.108.40.206 or 220.127.116.11?
Have a look at the doc links below gives you some info and ideal of possible steps.
i have a one standalone database 11gR2 on windows 2008 with ASM on SAN Storage ;
today the server was unable to reboot and it seems a board issue;
can i install oracle 11gR2 grid infrastructure and the database server on another windows server start the ASM instance and connect to existing diskgroups as the Storage is running normally?
just an overview over the steps would be great
Yes, you can do that without problem.
TIP: Install GI Standalone without LUN'S mapped.
Create a small partition (locally) to Create a ASM Instance and a Diskgroup (e.g +ASM_SPFILE) to Store (ASM SPFILE).
Then Map LUN'S to host and Mount Diskgroup. After that you can Create Database SID using ORADIM on Windows and use SRVCTL to add Database Instance on Oracle Restart.
