How to Remove a StorEdge A5x00 Array From a Running Cluster

Use this procedure to remove a StorEdge A5x00 array from a cluster. "Example--Removing a StorEdge A5x00 Array" shows you how to apply this procedure. Use the procedures in your server hardware manual to identify the StorEdge A5x00 array.

1. 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.

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

   # luxadm remove_device -F boxname

3. Remove the StorEdge A5x00 array and the fiber optic cables that are connected to the StorEdge A5x00 array.

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

4. On all nodes, remove references to the StorEdge A5x00 array.

   # devfsadm -C # scdidadm -C

5. If necessary, remove any unused host adapters from the nodes.

   For the procedure on removing host adapters, see the documentation that shipped with your nodes.
