------- Comment From [email protected] 2016-02-08 05:39 EDT------- Virt.NIC QDIO - depends on the z/VM layer configured, more details below Virt.NIC Hiper - always layer3 Virt.NIC OSM - that's dead code, does not occur, I will add the removal on my to do list, any default is ok Virt.NIC OSX - that's dead code, does not occur, I will add the removal on my to do list, any default is ok unknown - should hopefully not occur, thus any default is ok OSD_100 - both layers possible, use layer2 as default HSTR - token ring no longer supported, does not occur, has been layer3 only OSD_1000 - both layers possible, use layer2 as default OSD_10GIG - both layers possible, use layer2 as default OSD_FE_LANE - outdated type, does no longer occur, has been layer3 only OSD_TR_LANE - token ring no longer supported, does not occur, has been layer3 only OSD_GbE_LANE - outdated type, does no longer occur, has been layer3 only OSD_ATM_LANE - outdated type, does no longer occur, has been layer3 only OSD_Express - both layers possible, use layer2 as default HiperSockets - both layers possible, use layer3 as default OSN - special case, needed for an IBM product already approaching end of life time (end of service effective 2016-03-31), does not have a layer2 attribute at all, ignore? OSM_1000 - always layer2 OSX_10GIG - both layers possible, use layer2 as default
As you see, there are still some outdated OSA-types listed, which we have not yet removed to still enable running on old hardware. They are not critical, and you can configure them as you like. A problematic type is "Virt.NIC QDIO". Here qeth does not yet determine the layer of the z/VM VSWITCH automatically. zVM commands allow to determine the layer. You could first determine the name of the VSWITCH, a virtual NIC is connected to - with "vmcp q virtual nic <vdev>" . Sample: > vmcp QUERY VIRTUAL NIC f5f0 Adapter F5F0.P00 Type: QDIO Name: HYD1G1 Devices: 3 MAC: 02-12-34-56-78-90 VSWITCH: SYSTEM VSW444 Here "VSW444" is the name of the VSWITCH. Then you can determine the layer of the VSWITCH with "vmcp q vswitch <vswitch name>". Sample: > vmcp QUERY VSWITCH VSW444 VSWITCH SYSTEM VSW444 Type: QDIO Connected: 9 Maxconn: INFINITE PERSISTENT RESTRICTED ETHERNET Accounting: OFF ... The keyword here is "ETHERNET". In this case layer2 must be configured for the virtual NIC, otherwise layer3. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1541544 Title: ubuntu-installer makes a contradictional statement regarding layer2/layer3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1541544/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
