If your original node is one of the supported models, during the process of upgrading by moving storage you can convert the node to a drive shelf and then attach it to the new nodes in the same cluster.
Procedure
-
Replace the controller modules in the node you are converting with appropriate IOM modules.
- Set the drive shelf ID.
Each drive shelf, including the chassis, requires a unique ID.
- Reset other drive shelf IDs as needed.
- Turn off power to any drive shelves connected to the new nodes, and then turn off power to the new nodes.
- Cable the converted drive shelf to a SAS port on the new system, and, if you are using out-of-band ACP cabling, to the ACP port on the new node.
- Turn on the power to the converted drive shelf and any other drive shelves attached to the new nodes.
- Turn on the power to the new nodes, and then interrupt the boot process on each node by pressing Ctrl-C to access the boot environment prompt.
