  • 1.  NIM mksysb restore and additional vlans.

    Hi, I'm trying to restore an mksysb from a NIM server to an Lpar on a p750. The thing is that the way that the Lpar reaches the network is through a virtual adapter whith a vlan adapter on top of it, because on the vios servers this vlan is routed as an additional vlan.
    When I go to the SMS menu on the Lpar, it tries to reach the NIM server trhough the en0 (it has no en1 since it is a vlan adapter) and it does not reach the master.
    Is there a known workaround?.
    I can think of adding an adapter with an IP on the default vlan an boot/install trhough it but I'm asking just in case.
    Thanks in advance.
    Pablo.

    as you already suspect the vlan adapter is an aix virtual device, and sms does not provide the same functionality.
    anyway, why would you want to put a vlan adapter ontop of a virtual adapter? 2 (hypervisor) virtual adapters will do just the same (in terms of tagging), and your sms knows these and let you netboot.

    I've got the vlan adapter on top of the virtual adapter because my scenario is the following:

    2 vios
    For the vlan 161 I've got:
    SEA failover for developement and test partitions using this vlan.
    1 SEA on each vios and etherchannel for the production Lpars.

    So; the SEA Failover has vlan adapter 2 and additional vlans 161, and the SEAs for the etherchannel have vlan adapter 7 and 8 on vios1 and vios2 and additional vlans 161.
    Developements and test partitions are configured with virtal ethernet adapters using vlan id 2 and on top of it a vlan adapter whith vid 161.
    Production partitions are configured with an adapter with vlan id 7 and other whith vlan id 8 and an etherchanel whit ip 161.

    I'm not able to boot trhough the adapter on the developement/test partitions because of the vlan adapter.

    Anyway I figured it out booting from the Nim with a vlan visible from the master and after it is installed I had to change the default gateway, remove the ip on the virtual adapter, recreate the vlan adapter and change the host at /etc/hosts.

    Thanks
