    PRVF-4007 : User equivalence check failed for user "grid"

    915922
      Oracle Version 11.2.0.3.0 patched to 11.2.0.3.1
      I had installed GIU and RAC db on 2 node cluster

      but since yesterdy has this issue when running the commands

      [grid@vmorarac2 ~]$ cluvfy comp ocr -n all -verbose

      Verifying OCR integrity

      ERROR:
      PRVF-4008 : User equivalence unavailable on all the specified nodes
      Verification cannot proceed

      vmorarac1 and vmorarac2 r the two nodes

      as a grid user, from vmorarac1 i ran ssh vmorarac2 and it failed with above error and vice versa


      so i did the following

      from vmorarac1
      ssh vmorarac2
      yes and enter key
      exec /usr/bin/ssh-agent $SHELL
      /usr/bin/ssh-add

      i did the same on other node


      but the problem still exists.

            followed note on metalink which is same as per links you pasted

            How To Configure SSH for a RAC Installation [ID 300548.1]

            but still asks for password

            checked alert_vmorarac2.log

            [client(16003)]CRS-10051:CVU found following errors with Clusterware setup : PRVG-1101 : SCAN name "vmorarac-scan.pbi.global.pvt" failed to resolve
            PRVF-4657 : Name resolution setup check for "vmorarac-scan.pbi.global.pvt" (IP address: 152.144.199.201) failed

            PRVF-4664 : Found inconsistent name resolution entries for SCAN name "vmorarac-scan.pbi.global.pvt"



            but there has been no change to /etc/hosts file which has scan name in it

              Hi,

              SSH with passphrase is not supported for Oracle Clusterware 11g release 2 and later releases.

              So, I recommend you deconfigure SSH and use Automatic SSH Configuration During Installation

              2.14 Automatic SSH Configuration During Installation
              http://docs.oracle.com/cd/E11882_01/install.112/e22489/prelinux.htm#BABIIEHI

              or configure ssh manually following this steps:

              Configuring SSH Manually on All Cluster Nodes
              http://docs.oracle.com/cd/E11882_01/install.112/e22489/manpreins.htm#BABJBAEB

              PS: The note *How To Configure SSH for a RAC Installation [ID 300548.1]* has a discrepancy of informations about use passphrase on SSH configuration. (Is not clear about it)

                Hi Levi

                The RAC GI and db were working fine

                I had done successfull install on both the nodes vmorarac1/2

                I happen to see this problem this week when I ran the command cluvfy comp ocr -n all -verbose

                alert_vmorarac2.log

                [client(16003)]CRS-10051:CVU found following errors with Clusterware setup : PRVG-1101 : SCAN name "vmorarac-scan.pbi.global.pvt" failed to resolve
                PRVF-4657 : Name resolution setup check for "vmorarac-scan.pbi.global.pvt" (IP address: 152.144.199.201) failed
                PRVF-4664 : Found inconsistent name resolution entries for SCAN name "vmorarac-scan.pbi.global.pvt"

                  Hi,

                  The subject of thread "*PRVF-4007 : User equivalence check failed for user "grid*"

                  Now..
                  {code}
                  PRVF-4657 : Name resolution setup check for "vmorarac-scan.pbi.global.pvt" (IP address: 152.144.199.201) failed
                  PRVF-4664 : Found inconsistent name resolution entries for SCAN name "vmorarac-scan.pbi.global.pvt"
                  PRVF-4664 : Found inconsistent name resolution entries for SCAN name "vmorarac-scan.pbi.global.pvt"
                  {code}

                  If you can see are different issue.

                  If you are using DSN to resolve hostname "vmorarac-scan.pbi.global.pvt" check with "nslookup" if the name is resolved correctly.

                  If you are using Hosts File to resolve hostname "vmorarac-scan.pbi.global.pvt" you must configure only one ip (152.144.199.201) to resolve "vmorarac-scan.pbi.global.pvt" this entrie must be on host file of all nodes of cluster.
