There are three different kernel levels possible to determine the MAC address
for VSWITCH NICs:
- old kernels just using the old IPA READ MAC method
- intermediate kernels using DIAG 26C on the data subchannel (this results in
an allocation of a new MAC address)
- latest kernels using DIAG 26C on the read subchannel
Your dbginfo material shows there is still this extra MAC address
02-00-00-00-42-CD defined:
root@s390vsl205> vmcp -b 4k q v nic
Adapter 0700.P00 Type: QDIO Name: UNASSIGNED Devices: 3
MAC: 02-00-00-00-01-07 VSWITCH: SYSTEM VSWN1
Adapter 0800.P00 Type: QDIO Name: HYD1G1 Devices: 3
MAC: 02-00-00-00-42-CD VSWITCH: SYSTEM VSWNL2
MAC: 02-00-00-00-01-08 Device: 0802 Current
Can you redefine this NIC with "vmcp det nic 0800", "vmcp def nic 0800 type
qdio devices 3", "vmcp couple 0800 to VSWNL2"?
Then you should no longer see MAC: 02-00-00-00-42-CD. And as long you do not
run an intermediate kernel, there should no other MAC address show up anymore.
