68 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
2.10.1 Adding enclosures after the initial configuration
When the initial installation of the IBM Storwize V5000 Gen2 is complete, all expansion
enclosures and control enclosures that were purchased at that time must be installed as part
of the initial configuration. This process enables the system to make the best use of the
enclosures and drives that are available.
Adding a control enclosure
If you are expanding the IBM Storwize V5000 Gen2 after the initial installation by adding a
second I/O group (a second control enclosure), you must install it in the rack and connect it to
the SAN. Ensure that you rezone your Fibre Channel switches so that the new control
enclosure and the existing control enclosure are connected. For more information about
zoning the node canisters, see 2.2, “SAN configuration planning” on page 40.
After the hardware is installed, cabled, zoned, and powered on, a second control enclosure is
visible from the IBM Storwize V5000 Gen2 GUI, as shown in Figure 2-38.

Note: Adding a second I/O group (via second controller enclosure) is only supported on
the IBM Storwize V5000 Gen2 model V5030.
