当安装GI 11203时遇到

Cause
There's multiple likely causes:
Cause 1. OCR and Voting Disk devices are not managed by UDEV, thus UDEV rules doesn't have proper configuration for OCR and Voting disk devices
Cause 2. Due to unpublished bug 8726128, even UDEV is configured properly, the error still showed up on local node on RHEL4/OEL4

Solution
1. To keep OCR and Voting Disk device name persistent across node reboot with proper ownership and permission, they need to be managed by UDEV; if you have other tool for the same purpose, you can safely ignore the warning.
2. Unpublished bug 8726128 will be fixed in 11.2.0.2, if "ls -l name_of_ocr" command shows expected result, the error can be ignored

Note: its recommended to migrate OCR and Voting Disk to ASM once upgrade is finished; if Voting Disk is migrated to ASM, it will inherit underlying diskgroup redundance:
  To migrate OCR to ASM:
    $GRID_HOME/bin/ocrconfig -add DiskGroupName
    $GRID_HOME/bin/ocrconfig -delete Current_OCR_NAME

貌似都不是，但自己确认了实际都是正常的，选中忽略，在接下来的安装一切正常。
