NIM - MASTER - and inet alias IP

    Hello,

    I've just transformed a LPAR as a NIM master as a node in a PowerHA cluster.

    So my previous address which serves for nim connections is now a service IP address taht could switch (192.168.33.180).

    The goal is to move my NIM resource as a clusterized one.

    The problem: when I perform a mksysb, the resource cannot be created, and here is what complains nimlog:

    <Mon Jun 24 12:06:25 CEST 2013> <master> <5308650> <0042-053 nim: there is no NIM object named "mksysb_parlsn00-adm">
    <Mon Jun 24 12:06:27 CEST 2013> <master> <15728826> <0042-151 c_stat: the file "/export/nim/mksysb/mksysb.parlsn00-adm" has a file type of 0100000.
            This conflicts with the expected type of 040000.>
    <Mon Jun 24 12:06:27 CEST 2013> <master> <11141226> <0042-006 m_mkbosi: (From_Master) connect Error 0

    - I've tried to reconfigure all the nim server, but it automatically connect to the standby address (a private network) only used for HA purpose.
    And the command line cannot specify a default hostname.

    - Here are the definition of my IP:
    en1: flags=1e080863,4c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),LARGESEND,CHAIN>
            inet 192.168.35.180 netmask 0xffffff00 broadcast 192.168.35.255  ==> HA standby IP wher NIM serviec is connected to!
            inet 192.168.33.254 netmask 0xffffff00 broadcast 192.168.33.255 ==> persistent IP stuck to the machine
            inet 192.168.33.180 netmask 0xffffff00 broadcast 192.168.33.255 ==> service IP where I want to plug NIM movable service.
             tcp_sendspace 262144 tcp_recvspace 262144 rfc1323 1

    Any idea, or have I to abandon such an idea?

    Thanks.

    Loïc Sarrazin.

    instead of PowerHA

    Hi,

    yes I knew this method, but that's true that HA is not the good response (CPUID problem among others).

    Thank you
