Sun Cluster 2.2 System Administration Guide

Adding a Sun StorEdge MultiPack or Sun StorEdge D1000

You can add Sun StorEdge MultiPacks or Sun StorEdge D1000s to a Sun Cluster configuration at any time.

You must review the disk group configuration in your Sun Cluster configuration before adding a disk enclosure. The discussions in Chapter 2 in the Sun Cluster 2.2 Software Installation Guide, and in Appendix A, Administering Volume Managers, in this book, will help determine the impact of the disk enclosure on the configuration of disk groups.

How to Add a Sun StorEdge MultiPack or Sun StorEdge D1000

  1. Shut down one of the cluster nodes.

    Use the procedure in "Stopping the Cluster and Cluster Nodes", to shut down the node.

  2. Install an additional SBus card in the node, if necessary.

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

    Note -

    Install the SBus card in the first available empty SBus slot, following all other cards in the node. This ensures that 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 SCSI-2 cables to the disk enclosure.

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

  4. Set the SCSI initiator ID, as appropriate.

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

  5. Perform a reconfiguration reboot of the node. 


    ok boot -r

  6. Use 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

  7. Repeat Step 1 through Step 5 on other nodes connected to this disk enclosure.

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

    For example:


    phys-hahost1# haswitch phys-hahost2 hahost2

  9. Add the disks in the disk enclosures to the selected disk group.

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