Pinned topic NIM - MASTER - and inet alias IP

‏2013-06-24T13:18:01Z | nim

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.

    Try Enabling NIM alternate master support

    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
