Sun Open Telecommunications Platform 2.0 Administration Guide

ProcedureTo Prepare Hosts for Dual-Partition Upgrade

You must perform this procedure before you upgrade Sun Open Telecommunications Platform using dual-partition upgrade.

  1. Set the resource group property to false.

    clresourcegroup set -p RG_system=false otp-system-rg

    Reset the value to true after completing the live upgrade.

  2. Set up the ssh login between the hosts in the cluster.

    Perform this step on all the hosts in the cluster.

    1. Type the following command.

      ssh-keygen -t rsa

    2. Accept the default values on all nodes.

    3. Append the contents of the /.ssh/id_rsa.pub file to the /.ssh/authorized_keys2 file from each host to all the cluster hosts.

    4. Edit the /etc/ssh/sshd_config file. Set the value of the PermitRootLogin variable to yes.

    5. Restart the ssh instance.

      svcadm restart svc:/network/ssh:default

    6. Verify you are able to log in between all the cluster hosts without typing the password.

  3. Set the system property for the otp-system-rg variable to false.

    /usr/cluster/bin/scrgadm -c -g otp-system-rg -y rg_system=FALSE

  4. Partition the cluster.

    1. On the first host, unzip the cluster bundle.

      unzip -d /tmp_dir 2.0_mediadir/solaris_sparc/components/cluster.zip

      2.0_mediadir is the fully-qualified path name to the Sun OTP 2.0 installation source directory.

    2. Type the following command.

      /tmp_dir/cluster/Solaris_sparc/Product/sun_cluster/Solaris_10/Tools/scinstall

    3. Select Option #3: Manage a dual-partition upgrade.

    4. Assign the manager host to the second partition, and the managed host to the first partition. The managed host on the first partition will be halted.

      Note –

      The first host or the manager host must remain in the second partition.

    5. Boot the hosts in the first partition in the non-cluster mode.

      ok boot -x

    Note –

    For installing and administering Sun Cluster using the GUI, refer to Chapter 12, Administering Sun Cluster With the Graphical User Interfaces, in Sun Cluster System Administration Guide for Solaris OS.
