Storage Foundation for Oracle® RAC 7.4.1 Configuration and Upgrade Guide - Solaris

To perform the pre-upgrade tasks on the first half of the cluster

1. Back up the following configuration files: main.cf, types.cf, CVMTypes.cf, CFSTypes.cf, OracleTypes.cf, OracleASMTypes.cf, , PrivNIC.cf, MultiPrivNIC.cf, /etc/llttab, /etc/llthosts, /etc/gabtab, /etc/vxfentab, /etc/vxfendg, /etc/vxfenmode

   For example:

   # cp /etc/VRTSvcs/conf/config/main.cf \
   /etc/VRTSvcs/conf/config/main.cf.save
   # cp /etc/VRTSvcs/conf/config/types.cf \
   /etc/VRTSvcs/conf/config/types.cf.save
   # cp /etc/VRTSvcs/conf/config/OracleTypes.cf \
   /etc/VRTSvcs/conf/config/OracleTypes.cf.save
   # cp /etc/VRTSvcs/conf/config/PrivNIC.cf \
   /etc/VRTSvcs/conf/config/PrivNIC.cf.save
   # cp /etc/VRTSvcs/conf/config/MultiPrivNIC.cf \
   /etc/VRTSvcs/conf/config/MultiPrivNIC.cf.save

   The installer verifies that recent backups of configuration files in the VxVM private region are saved in /etc/vx/cbr/bk.

   If not, the following warning message is displayed: Warning: Backup /etc/vx/cbr/bk directory.

2. Stop all applications that are not configured under VCS but dependent on Oracle RAC or resources controlled by VCS. Use native application commands to stop the application.
3. If you plan to continue using Storage Checkpoint or storage tiering policies you created with a 5.0x or earlier version of Storage Foundation for Oracle RAC, complete the following preparatory step before migrating the SFDB repository database to 7.4.1.

4. Stop the applications configured under VCS. Stop the Oracle database:

   • If the Oracle RAC instance is managed by VCS:

     # hagrp -offline oracle_group -sys sys1
     # hagrp -offline oracle_group -sys sys2

   • If the Oracle RAC instance is not managed by VCS, log in as the Oracle user on one of the nodes in the first half of the cluster and shut down the instances:

     For Oracle RAC 12c or later:

     $ srvctl stop instance -db db_name \
     -node node_name

     For Oracle RAC 11.2.0.2 and later versions of 11g Release 2:

     $ srvctl stop instance -d db_name \
     -n node_name

     For Oracle RAC 11.2.0.1 and earlier versions:

     $ srvctl stop instance -d db_name \
     -i instance_name

5. • If the Oracle database is managed by VCS, set the AutoStart value to 0 to prevent the database service group from starting automatically when VCS starts:

     # haconf -makerw
     # hagrp -modify oracle_group AutoStart 0
     # haconf -dump -makero

   • If the Oracle database is not managed by VCS, change the management policy for the database to manual:

     For Oracle RAC 11g:

     $ srvctl modify database -d db_name -y manual

     For Oracle RAC 12c or later:

     $ srvctl modify database -db db_name -policy manual

6. Unmount the CFS file systems that are not managed by VCS.

   • Make sure that no processes are running which make use of mounted shared file system. To verify that no processes use the CFS mount point:

     # mount | grep vxfs | grep cluster

     # fuser -cu /mount_point

   • Unmount the CFS file system:

     # umount /mount_point

7. Stop the parallel service groups and switch over failover service groups on each of the nodes in the first half of the cluster:

   # hastop -local -evacuate

8. Unmount the VxFS file systems that are not managed by VCS.

   • Make sure that no processes are running which make use of mounted shared file system. To verify that no processes use the VxFS mount point:

     # mount | grep vxfs

     # fuser -cu /mount_point

   • Unmount the VxFS file system:

     # umount /mount_point

9. Verify that no VxVM volumes (other than VxVM boot volumes) remain open. Stop any open volumes that are not managed by VCS.

   # vxvol -g diskgroup stopall
   # vxprint -Aht -e v_open

10. Verify that only ports a, b, d, and o are open:

    # gabconfig -a
    GAB Port Memberships
    =======================================================
    Port a gen   79c302 membership 0123
    Port b gen   79c307 membership 0123
    Port d gen   79c306 membership 0123
    Port o gen   79c304 membership 0123

11. If you plan to upgrade the operating system, stop all ports.

    For versions up to 7.0:

    # /opt/VRTS/install/installsfrac<version> -stop sys1 sys2

    Where <version> is the specific release version.

    For 7.0 and later versions:

    # /opt/VRTS/install/installer -stop sys1 sys2
