## 4.4 Working with external storage controllers 

After the internal storage configuration is complete, you can find the MDisks that were created by using the internal drives in the MDisks by Pools window. When you use this window, you can manage all MDisks that are made up of internal and external storage. 

LUNs that are presented by external storage systems to IBM Storwize V5000 Gen2 are discovered as unmanaged MDisks. Initially, the MDisk is not a member of any storage pools, which means that it is not used by the IBM Storwize V5000 Gen2 storage system. 

For more information about external storage, see Chapter 11, “External storage virtualization” on page 607.
