SYMPTOMS                                                

After successful upgrade to 11gR2 GridInfrastructure clusterware, INS-20802 reported while running Oracle ClusterVerification Utility post check, installation logs located in$ORACLE_BASE/oraInventory/logs/installActions{$TIMESTAMP}.log shows similar entrieslike following:

INFO: PRVF-9802 : Attempt to get udev infofrom node "node1" failed

INFO: Checking udev settings for device"/dev/raw/raw1"

INFO: PRVF-5184 : Check of following Udevattributes of "node2:/dev/raw/raw1" failed: "[Group:Found='root' Expected='oinstall', Permissions: Found='0660'Expected='0640']"

INFO: PRVF-5186 : Check for Udevpermissions failed on node "node1"

Or

INFO: Checking udev settings for device"/dev/raw/raw1"

INFO: PRVF-5184 : Check of following Udevattributes of "node1:/dev/raw/raw1" failed: "[Group:Found='root' Expected='oinstall', Permissions: Found='0600'Expected='0640']"

INFO: PRVF-5184 : Check of following Udevattributes of "node2:/dev/raw/raw1" failed: "[Group:Found='root' Expected='oinstall', Permissions: Found='0600'Expected='0640']"

CAUSE                                                     

There's multiple likely causes:

Cause 1. OCR and Voting Disk devices arenot managed by UDEV, thus UDEV rules doesn't have proper configuration for OCRand Voting disk devices

Cause 2. Due to unpublished bug 8726128,even UDEV is configured properly, the error still showed up on local node onRHEL4/OEL4

SOLUTION                                                 

1. To keep OCR and Voting Disk device namepersistent across node reboot with proper ownership and permission, they needto be managed by UDEV; if you have other tool for the same purpose, you cansafely ignore the warning.

2. Unpublished bug 8726128 will be fixed in11.2.0.2, if "ls -l name_of_ocr" command shows expected result, theerror can be ignored

Note: its recommended to migrate OCR andVoting Disk to ASM once upgrade is finished; if Voting Disk is migrated to ASM,it will inherit underlying diskgroup redundance:

  Tomigrate OCR to ASM:

   $GRID_HOME/bin/ocrconfig -add DiskGroupName

   $GRID_HOME/bin/ocrconfig -delete Current_OCR_NAME

 Example:

   $GRID_HOME/bin/ocrconfig -add +DGOCW

   $GRID_HOME/bin/ocrconfig -delete /dev/raw/raw1

  Tomigrate Voting Disk to ASM:

   $GRID_HOME/bin/crsctl replace votedisk +DiskGroupName

  Example:

   $GRID_HOME/bin/crsctl replace votedisk +DGOCW
