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.
Logical unit numbers (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.
To learn more about external storage, see Chapter 11, "External storage virtualization" on
page 641.
