Adding new LUNs dynamically to a target ID

Dynamic Multi-Pathing (DMP) provides a Dynamic Reconfiguration tool to simplify the addition of new LUNs to a new or existing target ID. One or more new LUNs are mapped to the host by way of multiple HBA ports. An operating system device scan is issued for the LUNs to be recognized and added to DMP control.

Warning:

Do not run any device discovery operations outside of the Dynamic Reconfiguration tool until the device operation is completed.

In a cluster, perform the steps on all the nodes in the cluster.

To add new LUNs dynamically to a target ID

Start the vxdiskadm utility:
```
# vxdiskadm
```
Select the Dynamic Reconfiguration operations option from the vxdiskadm menu.
Select the Add LUNs option.
The following are sample EMC Symmetrix commands:
When the prompt displays, add the LUNs from the array.
Output similar to the following is displayed:

Select y to continue to add the LUNs to DMP.

DMP updates the operating system device tree and the VxVM device tree. The newly-discovered devices are now visible.
