How 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.
