        Hi Manish,

        I followed your procedure to find the WWID and configure the disks across the nodes, I checked with SAN Admin, he says that the disks are persistent and no issues with the allocation.
        scsimgr lun_map -D /dev/rdisk/disk76 | grep WWID

        After trying very hard with the 11gR2 RAC installation, we did 11gR1 installation successfully and will upgrade it to 11gR2, can you please share information regarding the upgrade from 11gR1 to 11gR2, I am currently following "*Oracle Database Upgrade Guide11g Release 2 (11.2) E17222-08*"

        Many thanks for providing great help.

            Hi,

            yes, LUNs are properly mapped across the nodes.

            By root user, Give the permissions & ownerships to /dev/oracle/* like below,

            # chown grid:asmadmin /dev/oracle/*
            # chmod 660 /dev/oracle/*

            and then try it again.


            Regards,
            Manish

              Hi Manish,

              Yes I gave the "grid:asmadmin" ownership to the disks and also the 660 file permissions, still the disks are not identified by the OUI.

              Can you please send the Oracle RAC 11gR2 installation procedure to "zed_clone@yahoo.com"

              Thanks!

                  Hi,

                  Thanks for sharing the installation procedure.

                  Its strange, I followed each and every step and still cannot list the disks in the OUI, your document has "oracle:asmadmin" ownership on the disk, I even tried it and still the same issue.
                  I think there is something to do with the ownership, its either "grid:asmadmin" or "oracle:asmadmin" or something else, but the oracle docs says that it should be "grid:asmadmin".
                  On the same disks I installed Oracle RAC 11gR1 successfully without any issue.

                    Hi,

                    the SCAN IPs can be configured in the Windows DNS server?
                    As you mentioned for a two node RAC cluster it requires the following IP configuration:

                    2 Public IPs
                    2 Private IPs
                    2 Virtual IPs
                    and 3 SCAN IPs

                    can you please explain the configuration of VIPs and SCAN IPs in 11gR2.
