You can ATTACH the additional first level OSA subchannels to the 2nd level system with the same address as the "primary" set used on the first level. For example, given: - Your real OSA has subchannels 1E00-1E1F defined for your VM LPAR - You dedicate 1E00-1E02 to your first level TCP/IP then you can dedicate 1E03-1E05 to the 2nd level guest as 1E00-1E02, so that it sees the same subchannel numberss. If your IOCP doesn't have spare subchannels, then use dynamic I/O to add them. Alternatively you can use a VSWITCH on the first level and have everyone use virtual NICs on that VSWITCH.
