If what you want to achieve is to have the 1st and 2nd level guests in the same IP subnet, you could do it a few ways... 1) At the first level directory, add one NICDEF statement for each of the guests in your second level z/VM to the directory entry for the 2nd level z/VM. The NICDEFs will attach the NICs to your VSWITCH. Inside the 2nd level system the virtual NICs will appear as a lot of OSAs -- DEDICATE the triplet for each of them to one of your 2nd level guests. 2) At the first level directory, add one NICDEF statement with DEVICES as large as you can make it to the directory entry for your second level z/VM. The NICDEF will attache the NIC to your VSWITCH. Inside the 2nd level system you would see a single OSA, but you DEDICATE a triplet to each of your 2nd level guests thereby sharing the virtual OSA between all your 2nd level guests. Those two both use the VSWITCH defined at the 1st level, but there are a couple of ways to get the end result by using a VSWITCH inside 2nd-level: 3) At the first level directory, add one NICDEF statement to the directory entry for your second level z/VM. Inside the 2nd level system, create a VSWITCH that connects to the virtual OSA. Connect all your 2nd level guests to the 2nd level VSWITCH. 4) At the first level directory, DEDICATE a triplet from the real OSA through to the 2nd level system. Inside the 2nd level system, create a VSWITCH that connects to the real OSA. Connect all your 2nd level guests to the 2nd level VSWITCH. Note that 1) is pretty much guaranteed to work, but is the most resource- -intensive (system and sys-prog) method. 2), 3) and 4) I've never done, but should work just fine. Of course if your secondary objective is to not run a TCPIP stack at all in 2nd level, disregard 3) and 4) (the 2nd-level VSWITCH obviously requires it). In this case, I'm sure you already realise that you'll only be able to reach consoles at 2nd level by DIALling from 1st level... :) Cheers, Vic Cross ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
