Sun Cluster 2.2 System Administration Guide

Adding a SPARCstorage Array

You can add SPARCstorage Arrays to a Sun Cluster configuration at any time.

You must review the disk group configuration in your cluster before adding a SPARCstorage Array. To determine the impact of the SPARCstorage Array on your disk group configuration, refer to the configuration planning information in the Sun Cluster 2.2 Software Installation Guide.

How to Add a SPARCstorage Array

  1. Shut down the cluster node that is to receive the new SPARCstorage Array.

    Use the procedure "How to Stop Sun Cluster on a Cluster Node" to shut down the node.

  2. Install the Fibre Channel SBus card (FC/S) in the node.

    Use the instructions in the hardware service manual for your Sun Cluster node to install the FC/S card.

    Note -

    Install the FC/S card in the first available empty SBus slot, following all other cards in the node. This will ensure the controller numbering will be preserved if the Solaris operating environment is reinstalled. Refer to "Instance Names and Numbering", for more information.

  3. Connect the cables to the SPARCstorage Array and FC/S card.

    Use the instructions in the hardware service manual for your Sun Cluster node.

  4. Perform a reconfiguration reboot of the node. 


    ok boot -r

  5. Run the haswitch(1M) command to switch ownership of all logical hosts that can be mastered to the rebooted node.


    phys-hahost1# haswitch phys-hahost2 hahost1 hahost2

  6. Repeat Step 1 through Step 4 on the other nodes that are connected to this SPARCstorage Array.

  7. Switch ownership of the logical hosts back to the appropriate default master, if necessary.


    phys-hahost1# haswitch phys-hahost2 hahost2

  8. Add the disks in the SPARCstorage Arrays to the selected disk group(s).

    Use the instructions in your volume manager documentation to add the disks to the selected disk group(s). Also, refer the Sun Cluster 2.2 Software Installation Guide for information on Solstice DiskSuite and VxVM.

  9. (Solstice DiskSuite configurations only) After adding the disks to the diskset by using the metaset(1M) command, run the scadmin(1M) command to reserve and enable failfast on the specified disks.


    phys-hahost1# scadmin reserve cNtXdYsZ
