Sun Cluster Software Installation Guide for Solaris OS

How 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

    Loads the device ID configuration table into the kernel


    Initializes the DID driver


    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.
