How to Replace a StorEdge A5x00 Array in a Running Cluster

Use this procedure to replace a failed StorEdge A5x00 array in a running cluster. "Example--Replacing a StorEdge A5x00 Array" shows you how to apply this procedure. This procedure assumes that you are retaining the disk drives.

If you are replacing your disk drives, see "How to Replace a Disk Drive in a StorEdge A5x00 Array in a Running Cluster".

  1. If possible, back up the metadevices or volumes that reside in the StorEdge A5x00 array.

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

  2. Perform volume management administration to remove the StorEdge A5x00 array from the configuration.

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

  3. On all nodes that are connected to the StorEdge A5x00 array, run the luxadm remove_device command.


    # luxadm remove_device -F boxname
    
  4. Disconnect the fiber optic cables from the StorEdge A5x00 array.

  5. Power off and disconnect the StorEdge A5x00 array from the AC power source.

    For more information, see the Sun StorEdge A5000 Installation and Service Manual and the Sun StorEdge A5000 Configuration Guide.

  6. Connect the fiber optic cables to the new StorEdge A5x00 array.

  7. Connect the new StorEdge A5x00 array to an AC power source.

  8. One at a time, move the disk drives from the old StorEdge A5x00 disk array to the same slots in the new StorEdge A5x00 disk array.

  9. Power on the StorEdge A5x00 array.

  10. Use the luxadm insert_device command to find the new StorEdge A5x00 array.

    Repeat this step for each node that is connected to the StorEdge A5x00 array.


    # luxadm insert_device
    

  11. On all nodes that are connected to the new StorEdge A5x00 array, upload the new information to the DID driver.

    If a volume management daemon such as vold is running on your node, and you have a CD-ROM drive that is connected to the node, a device busy error might be returned even if no disk is in the drive. This error is an expected behavior.


    # scgdevs
    
  12. Perform volume management administration to add the new StorEdge A5x00 array to the configuration.

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

Example--Replacing a StorEdge A5x00 Array

The following example shows how to apply the procedure for replacing a StorEdge A5x00 array.


# luxadm remove_device -F venus1
