How are you backing up GI Home?

You might be better off to simply install Grid Infrastructure = from scratch on the DR Site. The issue is that any cloned (pure filesystem = copy), will refer to the OCR/Voting disks that will contain registry entrie= s to the resources within a cluster. You would at the very least need a) OC= R/Voting disk backups and b) the GI Home binaries. Then, most likely, unzip= binaries, restore disks and attach storage, hope that your host names are = the same, and reconfigure GI.

To go through that process would require a lot of time,= where as a fresh install is cleaner. The steps for those are very well doc= umented :)

Cheers,
Maaz

Create Dataguard from 4node to 2 node is= not an issue. The main requirement is how to clone Oracle Grid infrastruct= ure using the backup taken for software on Primary site. It is DR exercise = where Database restore is not a challenge as long as Grid infrastructure is= ready. So key challenges are to identify the various script to be executed= after the Software from one of the node is restored on the DR exercise server and ho= w to create the various configuration files including ASM based ocr/voting = disk and other ASM configuration.

Once this is done= , Database cloning using Tape restore will not be an issue. This is one tim= e exercise to check and document the procedure to rebuild the environment f= rom offshore tape backup

Hi Sanjay,=A0

Are you looking for 4-node to 2-node DR setup?=A0

If so you can refer below links. I usually r= efer MAA documents.=A0

= documentsay point to 2-node standby or 3-node, you may need to perform chan= ges only few parameters like FAL_SERVER, LOG_ARCHIVE_CONFIG so on. You will= get idea if you refer those links.=A0

Documents you may not get exactly as per= your environment, you can refer them and of course you can modify steps as requ= ired.=A0

Hope this helps.=A0
<= div>
But the below question is confusing still= , can you describe more ?=A0

what are the steps for Grid Infrasturcture cloning?

Thank you,
