    Hello All,

     

    I'm not able to perform DLPAR activities on lpars patched to an HMC, resulting following error as below:

    A RMC network connection to the partition is not present.verify the network settings on the partition and the HMC
    if you select OK you will have to restart the partition for the resource changes to take effect.

     

    I have tried these, but still issue is not resolved :

    HMC DLPAR:
    **************

    /usr/sbin/rsct/bin/rmcctrl -z   = stops all the deamons
    /usr/sbin/rsct/bin/rmcctrl -A    = starts (Adds?) all the deamons
    /usr/sbin/rsct/bin/rmcctrl -p    = resets Peer conections
    /usr/sbin/rsct/install/bin/recfgct

    Any suggestions please...

    You need to check the status of RMC "network" rather than just stopping and starting daemons: try this

    /usr/sbin/rsct/bin/rmcdomainstatus -s ctrmc -a IP

    from the hmc, do: lssyscfg -r lpar -m <CEC name> -F rmc_ipaddr,lpar_id,name,state,rmc_state

    also ping the nodes from the hmc and ping the hmc from the nodes

    If basic networking connectivity is there, by experience (DLPAR not working with same 'A RMC network connection to the partition is not present.': 

    odmdelete -o CuAt -q "name='cluster0'" 

    was needed on the LPAR (together with other commands listed).

    Check the caution concerning clustering.

    Also ssh to your hmc.... do the following command... and you should see DCaps have a none zero value. One issue is if you are using the firewall function on the hmc make sure it is not blocking the packets.
