At this point, you can configure zones for hosts by using the primary host attach ports (virtual
WWPNs) of the IBM Spectrum Virtualize ports, as shown in bold in the output of Example 5-8
on page 232.
5.4.3 Enabling NPIV on an existing system
When IBM Spectrum Virtualize systems that are running code before 7.7.1 are upgraded to
version 7.7.1 or higher, the NPIV feature is not turned on by default, because it might require
changes to host side zoning. Enabling N_Port ID Virtualization (NPIV) on an existing system
requires that you complete the following steps after meeting the prerequisites:
1. Audit your SAN fabric layout and zoning rules, because NPIV has stricter requirements.
Ensure that equivalent ports are on the same fabric and in the same zone. For more
information, see the topic about zoning considerations for N_PortID Virtualization in IBM

2. Check the path count between your hosts and the IBM Spectrum Virtualize system to
ensure that the number of paths is half of the usual supported maximum. For more
information, see the topic about zoning considerations for N_Port ID Virtualization in IBM

3. Run the lstargetportfc command to note down the primary host attach WWPNs (virtual
WWPNs), as shown in bold in Example 5-14.
