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 return the storage configuration 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 the procedures in How to Handle Storage Reconfiguration During an Upgrade.

Before You Begin

Return the storage topology to its original configuration. Check the configuration of the devices that were flagged as possibly being replaced, including the cabling.

  1. On each node of the cluster, become superuser.

  2. Update the DID driver on each node of the cluster.

    phys-schost# scdidadm -ui
    phys-schost# scdidadm -r

    Loads the device–ID configuration table into the kernel.


    Initializes the DID driver.


    Reconfigures the database.

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

  3. If the scdidadm command returned any error messages in Step 2, make further modifications as needed to correct the storage configuration, then repeat Step 2.

Next Steps

Return to the remaining upgrade tasks. Go to Step 4 in How to Upgrade Sun Cluster 3.2 Software (Standard).
