How to Replace a Netra D130/StorEdge S1 Enclosure in a Running Cluster

Use this procedure to replace a Netra D130/StorEdge S1 enclosures. This procedure assumes that you want to retain the disk drives in the Netra D130/StorEdge S1 enclosures you are replacing and to retain the references to these same disk drives.

If you want to replace your disk drives, see "How to Replace a Netra D130/StorEdge S1 Disk Drive 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 disk array from the configuration.

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

  3. Disconnect the SCSI cables from the Netra D130/StorEdge S1 enclosures, disconnecting the cable on the SCSI OUT connector first, then the cable on the SCSI IN connector second (see Figure 10-7).

  4. Power off, and disconnect the Netra D130/StorEdge S1 enclosures from the AC power source.

    For more information, see the documentation that shipped with your Netra D130/StorEdge S1 enclosures and the labels inside the lid of the Netra D130/StorEdge S1 enclosures.

  5. Connect the new Netra D130/StorEdge S1 enclosures to an AC power source.

    Refer to the documentation that shipped with the Netra D130/StorEdge S1 enclosures and the labels inside the lid of the Netra D130/StorEdge S1 enclosures.

  6. Connect the SCSI cables to the new Netra D130/StorEdge S1 enclosures, reversing the order in which you disconnected them (connect the SCSI IN connector first, then the SCSI OUT connector second). See Figure 10-7.

  7. Move the disk drives one at time from the old Netra D130/StorEdge S1 enclosures to the same slots in the new Netra D130/StorEdge S1 enclosures.

  8. Power on the Netra D130/StorEdge S1 enclosures.

  9. On all nodes attached to the Netra D130/StorEdge S1 enclosures, run the devfsadm(1M) command.


    # devfsadm

  10. One at a time, shut down and reboot the nodes connected to the Netra D130/StorEdge S1 enclosures.


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

    For more information on shutdown(1M), see the Sun Cluster 3.0 12/01 System Administration Guide.

  11. Perform volume management administration to add the Netra D130/StorEdge S1 enclosures to the configuration.

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