Two node RAC
Windows 2003 server
raw device, OCFS

One of the drives (H) which has the data files is out of space, current size 250G.

We need to extend it, so our windows admin added another 50G. Not sure how to extend the partition(ocfs created) in a RAW device to make the drive full 300G

What tools/utility to use?

Do we need to bring down the database while we do this.

Thanks for your help

    just wanted to update with our resolution

    metalink note 229060.1

    This is accomplished with OCFSFORMAT Utility

    The ocfsformat.exe utility is found in the following directories, depending on the version of clusterware:

    1. Assuming the P: drive is a volume that will store only Oracle database files, and assuming a cluster size of 1024k (1MB) and a vlume name of DATA, the following syntax will format the drive:

    ocfsformat /m P: /c 1024 /v DATA /f /d /a

    Using the Windows Disk Management tool:
    1. Go to Start -> Programs -> Administrative Tools -> Computer Management and choose Disk Management.

    2. Right click on the desired physical hard drive and choose:

    New Partition -> Extended Partition.

    We recommend creating the Extended Partition using the entire size of the disk.

    3. Right click on the Extended Partition and choose: 'New Logical Drive'

    4. Once the remote nodes see the drives, be sure to remove any drive letters:

    5. ocfsformat.exe is found in: CRS_HOME\cfs

    where CRS_HOME is the directory where the Oracle Clusterware is installed.

    6. C:\oracle\product\10.2.0\crs\cfs>ocfsformat
    Usage: OcfsFormat /m <linkName> /c <ClusterSize in KB> /v <Volume Label> /f /a

    Example : ocfsformat /m P: /c 1024 /v DATA /f /d /a

    7. Once the drive is formatted, verify that the remote nodes can now see the drive
