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 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.
