Good evening!

This is the first time I've got a job in Windows platform, I've worked as DBA with Unix/Linux still now.

I received one command: Install Oracle 11gR2 on Windows 7 Enterprise, so that, I plan to create one Partition (really, not mounted, this is Unallocated partition by Partition Magic 3rd software) which will contain datafile in it.

And, when I install 11gR2 Grid, the step ASM creation did not recorgnize the Unallocated Partition I created.

May you guide me to complete this?

Thank you!

What did you tell Grid Infratructure to use as a discovery string? If you gave the partition a drive letter (for example, D) then you can specify it as
\\.\D:
otherwise, try this discovery string:
\\.\*
which will discover all your partitions with and without drive letters (including C:, better not try to use it). I haven't worked on Windows 7, but that is how I've done it on earlier versions.
Please feed back on this, I'ld like to know how (if) it works.

Docs are saying :
ASM only discovers disks that contain a partition table.
http://docs.oracle.com/cd/B28359_01/server.111/b31107/asmdiskgrps.htm

So, please read below link :
http://docs.oracle.com/cd/B19306_01/install.102/b15681/reqs.htm

And Search :
Step 2: Creating the Disk Partitions

Hope I am near to answer.

Thank you for your reply!

I said to ASM's discovery feature, and, the discovery pointed me to the

'\Device\Harddisk0\Partition 0';
'\Device\Harddisk0\Partition 1';
'\Device\Harddisk0\Partition 2';
'\Device\Harddisk0\Partition 3';

In which, Partition 0 is boot loader, 1 is C driver, 2 is D driver and 3 is E driver. I knew exactly because of the size of each Partition. The unallocated partition was 50gb, and remain were bigger than 50g (C is 120gb, D is 100gb and E is 120gb).

I did not know why the discovery feature did not recorgnize the Unallocated Partition?

Thank you!
