Moving Oracle Clusterware Files from NFS to Oracle ASM

If Oracle Cluster Registry (OCR) and voting files are stored on Network File System (NFS), then move these files to Oracle ASM disk groups before upgrading Oracle Grid Infrastructure.

  1. As Oracle Grid Infrastructure installation owner (grid), create the Oracle ASM disk group using ASMCA.

    Follow the steps in the ASMCA wizard to create the Oracle ASM disk group, for example, DATA.

  2. As grid user, move the voting files to the Oracle ASM disk group you created:
    crsctl replace votedisk +DATA 

    The output of this command is as follows:

    CRS-4256: Updating the profile
    Successful addition of voting disk 24c6d682874a4f1ebf54f5ab0098b9e4.
    Successful deletion of voting disk 1b5044fa39684f86bfbe681f388e55fb.
    Successfully replaced voting disk group with +DATA_DG_OCR_VDSK.
    CRS-4256: Updating the profile
    CRS-4266: Voting file(s) successfully replaced
  3. As grid user, check the Oracle Cluster Registry (OCR) status:

    The output of the command is as follows:

    Status of Oracle Cluster Registry is as follows :
             Version                  :          4
             Total space (kbytes)     :     409568
             Used space (kbytes)      :       1380
             Available space (kbytes) :     408188
             ID                       :  288871063
             Device/File Name         : /oradbocfs/storage/12101/ocr
             Device/File integrity check succeeded
             Cluster registry integrity check succeeded
  4. As root user, move the OCR files to the Oracle ASM disk group you created:
    ./ocrconfig -add +DATA 
  5. As root user, delete the Oracle Clusterware files from the NFS location:
    ./ocrconfig -delete ocr_file_ path_previously_on_nfs
