  • 1.  LPM & using different vSwitch on target ?

    Hello,

    Quick and stupid q;  Can you force LPM somehow to use different vSwitch & VLAN on destination frame compared to source?

    E.g on source VM has vSwitch Happy, VLAN ID 123; and on destination it would be Weekend, VLAN 234?
    (Actual L2 level network would remain identical (IP address, subnet, gw, mask etc))

    Or does one need to "fake" the old switch & VLAN info on destination; do offline LPM; modify VM profile to be correct & then re-activate VM.

    Hello Tommi
    yes you can switch to another vSwitch since last year....

    Hi 

    I hope that you have a migration strategy :)

    You have HMC command to it dynamically without downtime :

    hscroot@hmcXXX:~> migrlpar -o m -m CPU-FRMXXXX -t CPU-FRMXXXY -p LPAR1 -i 'shared_proc_pool_name=shp_app,"vswitch_mappings=180/VS_P8/VS_LAN_PROD_CMN,3358/VS_P8/VS_LAN_PROD_CMN"'

    Where :
    CPU-FRMXXXX : frame source
    CPU-FRMXXXY: target frame
    shp_app: shared pool name, same on target frame
    LPAR1 : partition name
    vswitch_mappings: on frame source, my partition LPAR1 VLAN's 180/3358 configured on Vswitch VS_P8, and on target frame i changed Vswitch name to VS_LAN_PROD_CMN. no change of subnet configuration.

    About this point :
    live-partition-mobility-lpm-move-pvidvlan-one-vswitch-another-vswitch-across-dual-hmc-using-hmc-cli-command

    Hope that help you.

    Hi,

    Thanks for the reply! And sure; "Strategy is my middle name" , so no worries :D 

    Actually this would just be a POC for this kind of migrations, not doing any production stuff right away :)

    Hi,

    One more question related to this...From CLI it is possible to give new vSwitch...but how about the VLAN ID?
    Is it possible to change VLAN ID as well, or does it need to remain the same as in source frame?
