2.10.1 Adding Enclosures after initial configuration
When the initial install of the IBM Storwize V5000 is complete, all expansion enclosures and
control enclosures that were purchased at that time should 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 after the initial installation by adding a second
I/O Group (a second control enclosure) or adding expansion enclosures, follow the physical
installation procedures as described in IBM Storwize V5000 Quick Installation Guide Version
6.4.1, GC27-4219. For more information about zoning the node canisters, see 2.2, “SAN
configuration planning” on page 31.
After the hardware is installed, cabled, and powered on, a second control enclosure is added.
Complete the following steps to use the management GUI to configure the new enclosure:
1. In the Monitoring tab, select Actions Add Enclosures Control and Expansions, as
shown in Figure 2-33.

2. If the control enclosure is properly configured, the new control enclosure is identified in the
next window, as shown in Figure 2-34.

Click the Identify option to turn on the identify LEDs of the new canister, if required.
Otherwise, click Next.
3. You might receive a message that indicates the software level of the new control enclosure
needs upgrading, as shown in Figure 2-35. This is normal if the new enclosure is at a
lower level of code than your existing IBM Storwize V5000. Click OK.
Figure 2-35 New control enclosure software upgrade warning
It can take several minutes for the software upgrade to complete.
Chapter 2. Initial configuration 61
After the code upgrade completes or if the new enclosure is already at the same level, the
IBM Storwize V5000 adds the new enclosure to the configuration, as shown in
Figure 2-36.
Figure 2-36 Add enclosure complete
Because the new control enclosure forms an I/O Group of its own, it appears as a single
enclosure in the rack. The original I/O Group is not shown even though they are part of the
same clustered system. The wording in the window is also misleading. By clicking the
enclosure that is shown, you see the candidate nodes that are to be added to the system.
The empty spaces do not actually do anything. If no new hardware is shown, check your
cabling and zoning and use the Refresh option. Be aware the Refresh option also is
disabled in subsequent windows if you use it. Therefore, if you still cannot see the new
hardware after a refresh, you might have to stop the process by clicking Cancel, correcting
any physical connectivity issues or hardware issues, and then beginning the process of
adding an enclosure again.
4. To add the enclosure, select the new enclosure and click Finish. The task to add the
enclosure completes, as shown in Figure 2-37 on page 62.
Important: It is recommended that you have your system at the latest level of code
before any enclosure expansions are done.

5. Click Close to finish the wizard. You are prompted to configure the new storage, as shown
in Figure 2-38.

At this point, you can choose Configure Storage or No to quit the wizard and return to the
IBM Storwize V5000 GUI.
Chapter 2. Initial configuration 63
If you choose to configure storage, a wizard starts, as shown in Figure 2-39.

6. Select Yes to have the IBM Storwize V5000 automatically configure the new drives as
candidates. Select No to exit the wizard.
The wizard prompts you to configure the new internal storage, as shown in Figure 2-40.
