3.  Upgrading Sun Cluster Software Recovering From Storage Configuration Changes During Upgrade  Previous   Contents   Next 
   
 

ProcedureHow to Handle Storage Reconfiguration During an Upgrade

Any changes to the storage topology, including running Sun Cluster commands, should be completed before you upgrade the cluster to Solaris 9 software. If, however, changes were made to the storage topology during the upgrade, perform the following procedure. This procedure ensures that the new storage configuration is correct and that existing storage that was not reconfigured is not mistakenly altered.

  1. Ensure that the storage topology is correct.

    Check whether the devices that were flagged as possibly being replaced map to devices that actually were replaced. If the devices were not replaced, check for and correct possible accidental configuration changes, such as incorrect cabling.

  2. Become superuser on a node that is attached to the unverified device.

  3. Manually update the unverified device.
    # scdidadm -R device
    -R device

    Performs repair procedures on the specified device

    See the scdidadm(1M) man page for more information.

  4. Update the DID driver.
    # scdidadm -ui
    # scdidadm -r
    -u

    Loads the device ID configuration table into the kernel

    -i

    Initializes the DID driver

    -r

    Reconfigures the database

  5. Repeat Step 2 through Step 4 on all other nodes that are attached to the unverified device.

  6. Return to the remaining upgrade tasks.

ProcedureHow to Resolve Mistaken Storage Changes During an Upgrade

If accidental changes are made to the storage cabling during the upgrade, perform the following procedure to change the storage configuration back to the correct state.


Note - This procedure assumes that no physical storage was actually changed. If physical or logical storage devices were changed or replaced, instead follow procedures in How to Handle Storage Reconfiguration During an Upgrade.


  1. Change the storage topology back to its original configuration.

    Check the configuration of the devices that were flagged as possibly being replaced, including the cabling.

  2. As superuser, update the DID driver on each node of the cluster.
    # scdidadm -ui
    # scdidadm -r
    -u

    Loads the device-ID configuration table into the kernel

    -i

    Initializes the DID driver

    -r

    Reconfigures the database

    See the scdidadm(1M) man page for more information.

  3. Did the scdidadm command return any error messages in Step 2?

    • If no, proceed to Step 4.

    • If yes, return to Step 1 to make further modifications to correct the storage configuration, then repeat Step 2.

  4. Return to the remaining upgrade tasks.

Sun Management Center Software Upgrade

This section describes how to upgrade from Sun Management Center 2.1.1 to either Sun Management Center 3.0 software or Sun Management Center 3.5 software on a Sun Cluster 3.1 10/03 configuration.

ProcedureHow to Upgrade Sun Management Center Software

  1. Have available the following items:

    • Sun Cluster 3.1 10/03 CD-ROM or the path to the CD-ROM image. You use the CD-ROM to reinstall the Sun Cluster 3.1 10/03 version of the Sun Cluster-module packages after you upgrade Sun Management Center software.

    • Sun Management Center documentation.

    • Sun Management Center patches and Sun Cluster-module patches, if any.

      See "Patches and Required Firmware Levels" in Sun Cluster 3.1 Release Notes for the location of patches and installation instructions.

  2. Stop any Sun Management Center processes.

    1. If the Sun Management Center console is running, exit the console.

      In the console window, select File>Exit from the menu bar.

    2. On each Sun Management Center agent machine (cluster node), stop the Sun Management Center agent process.
      # /opt/SUNWsymon/sbin/es-stop -a

    3. On the Sun Management Center server machine, stop the Sun Management Center server process.
      # /opt/SUNWsymon/sbin/es-stop -S

  3. As superuser, remove Sun Cluster-module packages.

    Use the pkgrm(1M) command to remove all Sun Cluster-module packages from all locations listed in the following table.

    Location

    Package to Remove

    Each cluster node

    SUNWscsam, SUNWscsal

    Sun Management Center console machine

    SUNWscscn

    Sun Management Center server machine

    SUNWscssv

    Sun Management Center help-server machine

    SUNWscshl

    If you do not remove the listed packages, the Sun Management Center software upgrade might fail because of package dependency problems. You reinstall these packages in Step 5, after you upgrade Sun Management Center software.

  4. Upgrade the Sun Management Center software.

    Follow the upgrade procedures in your Sun Management Center documentation.

  5. As superuser, reinstall Sun Cluster-module packages to the locations listed in the table below.
    # cd /cdrom/suncluster_3_1_u1/SunCluster_3.1/Packages/
    # pkgadd module-package

    Location

    Package to Install

    Each cluster node

    SUNWscsam, SUNWscsal

    Sun Management Center server machine

    SUNWscssv

    Sun Management Center console machine

    SUNWscshl

    Sun Management Center help-server machine

    SUNWscshl

    You install the help-server package SUNWscshl on both the console machine and the help-server machine.

  6. Apply any Sun Management Center patches and any Sun Cluster-module patches to each node of the cluster.

  7. Restart Sun Management Center agent, server, and console processes.

    Follow procedures in How to Start Sun Management Center.

  8. Load the Sun Cluster module.

    Follow procedures in How to Load the Sun Cluster Module.

    If the Sun Cluster module was previously loaded, unload the module and then reload it to clear all cached alarm definitions on the server. To unload the module, select Module=>Unload Module from the console's Details window.
