How to Replace a StorEdge D1000 Disk Array in a Running Cluster

Use this procedure to replace a StorEdge D1000 disk array in a running cluster. This procedure assumes that you are retaining the disk drives in the disk array you are replacing and you are retaining the references to these same disk drives.

If you are replacing your disk drives, see "How to Replace a Disk Drive in a StorEdge D1000 Disk Array in a Running Cluster".

  1. If possible, back up the metadevices or volumes that reside in the disk array.

    For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

  2. Perform volume management administration to remove the StorEdge D1000 disk array from the configuration.

    For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

  3. Disconnect the SCSI cables from the StorEdge D1000 disk array, removing them in the order that is shown in Figure 5-4.

  4. Power off and disconnect the StorEdge D1000 disk array from the AC power source.

    For the procedure on powering off a StorEdge D1000 disk array, see the Sun StorEdge A1000 and D1000 Installation, Operations, and Service Manual.

  5. Connect the new StorEdge D1000 disk array to an AC power source.

  6. Connect the SCSI cables to the new StorEdge D1000 disk array, reversing the order they were disconnected, as shown in Figure 5-4.

  7. Move the disk drives one at a time from the old StorEdge D1000 disk array to the same slots in the new StorEdge D1000 disk array.

  8. Power on the StorEdge D1000 disk array.

    For the procedure on powering on a StorEdge D1000 disk array, see the Sun StorEdge A1000 and D1000 Installation, Operations, and Service Manual.

  9. On all nodes that are attached to the StorEdge D1000 disk array, run the devfsadm(1M) command.


    # devfsadm

  10. One at a time, shut down and reboot the nodes that are connected to the StorEdge D1000 disk array.


    # scswitch -S -h nodename
# shutdown -y -g0 -i6

    For more information on shutdown procedures, see the Sun Cluster 3.0 U1 System Administration Guide.

  11. Perform volume management administration to add the StorEdge D1000 disk array to the configuration.

    For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.
