Preparation

 

Complete the following steps to prepare for the upgrade:

  1. Verify that all your front-end S or SM nodes are configured with matching keys in the spi.ini file. For details, see the spi.ini file section in the SBR Carrier Reference Guide, and ensure that all your S or SM nodes have the same keys and are listed in the [Hosts] section.

    Caution

    Do not proceed with this upgrade until all your S or SM nodes are configured with matching keys and are listed in the [Hosts] section of the spi.ini file. Failure to do so will cause the upgrade to fail.

  2. Copy the sbr-cl-8.5.0.R-1.sparc.tgz software distribution package to every node in the cluster, regardless of its role (S, SM, D, and M nodes). Copy the package to the /opt/tmp directory or another location with enough disk space, and unzip and un-tar the distribution package.

    For example:

    cd /opt/tmp

    gunzip sbr-cl-8.5.0.R-1.sparc.tgz

    tar xf sbr-cl-8.5.0.R-1.sparc.tar

  3. (Optional) For simplicity, in this procedure the entire distribution is copied to every node in the cluster. If you have limited disk space, you can optionally just copy the file *mysqlcluster*.tar.gz to every data (D) node and management (M) node, or mount it over NFS. This is the only file that is actually required on data nodes and management (M) nodes. If you are comfortable with Solaris, you can choose to unpack the entire distribution only on the S and SM nodes, and copy just *mysqlcluster*.tar.gz to the M and D nodes. If you choose this advanced method, you must be sure to unpack the entire distribution on all S or SM nodes. Note the path to the file *mysqlcluster*.tar.gz on your D nodes, for example: /opt/tmp/JNPRsbr.pkg/reloc/radius/install/ndb/bin/*mysqlcluster*.tar.gz.

    Note

    When SBR Carrier is upgraded from a release earlier than 7.4.0 (inclusive) to 7.4.1 or a later release, the /opt/tmp/JNPRsbr.pkg/reloc/radius/install/ndb/bin/ path contains two versions of MySQL files. We recommend that you use the latest version of MySQL file.

  4. Verify that you have more than 6 GB of disk space remaining on each node running SBR (S or SM nodes) after copying the entire distribution package.

  5. Verify that you have more than 1 GB of disk space remaining on each D node after copying the package.

  6. Verify that you have more than 1 GB of disk space remaining on each M node after copying the package.
