Re: hipersockets on a VM layer 2 vswitch
Yes but the layer 2 vswitch is running on z/VM ver. 5.4. Does this mean we will need to set up a layer 2 hipersocket on the z/OS side as well?

Re: 回复： Does OSA Express2 Ethernet su pport zVM layer2
Greetings, I saw this post and would like to get some verification on running both layer 2 and layer 3 on the same OSA. So we can now have say a z/VM running Linux guest on a layer 2 to an OSA along with a layer 3 TCP stack on the same z/VM using the same OSA? Would we be able to also have other LPARS either z/VM or z/OS share this same OSA with layer 3 as well ?

But what won't work on a z900, is sharing the osa with layer 2 and layer 3 traffic. As I recall, the first to connect to the OSA could set the mode (2 or 3) and all other shared connections have to use the same mode (just like the portname). The restriction got lifted with z990, there you can use the same shared OSA, mixing layer 2 and layer 3 connections.

Re: Does OSA Express2 Ethernet support zVM layer2 mode
Yes the OSA does support the Layer 2. It took us some time and effort but it does work. Are you setting this up so that it allows you the ability to move Linux guest from one VM to another while retaining it's IP address? If so you will need to start assigning MAC addresses and keeping track of that as well. This is what we used to set the layer 2 OSA You will need to set the group: You will also need to set the group: CP SET PORT GROUP GLAN515 JOIN F### CP DEF VSWITCH VSWF### ETH VLAN 515 RDEV F### NAT 515 PORTN OSAPORT CP SET VSWITCH VSWF### GRANT X X = guest name or user account note you will need to have a LAN to point too.

Greetings, Have you been successful with the install over an OSA defined on a layer 2 network? We are running z/VM 5.4 with the latest PTF's and SUSE 10 SP2 trying to perform the install using the IBM scripts. It is failing every time during the re-boot phase of the install.

We are having an issue with the build of a Linux guest defined for a layer 2 network. While the Linux build is starting it goes out to another Linux guest on another z/VM LPAR to download the binaries. *** Error while accessing the FTP server: Failed to connect to FTP server *** Could not find the SUSE Linux Enterprise Server 10 Installation Source.

Are there any tricks to get the installs to work? The theory is that with the layer 2 network in place we will be able to move Linux guest from one z/VM to another and potentially move from one box to another box as long as the OSA's on them are connected to the same layer 2 network and that the OSA's are defined the same so that the Linux guest can retain their IP address's no matter which box they are running. Supposedly for load balancing and when maintenance is required on the z/VM systems there will be minimal outages on the Linux guests. Hopefully I have made some sense.
Re: Linux install on a z/VM 1st level with an OSA defined as layer 2 network
Thanks, We were able to get past the FTP error. The issue was within the layer 2 VSWITCH definitions. We needed to have the VLAN and the NAT LAN statement set to the same LAN name ( 515 ). Now we are able to ping the VM machine on the layer 2 along with the linux guest when the first phase of the install has completed. Now we are running into another problem which seems to be with the Linux install script issue working on the layer 2 network. The first phase does runs, but the phase 2 part fails. Below are the console messages leading up to the failure and the VNC connection error.
