Pinned topic Help with fencing x3650 M3 and Redhat Cluster Suite

‏2011-04-05T08:50:29Z |
Hi.

We have two x3650 M3 with Virtual Media Key. Our plan is install Redhat with Cluster Suite role in this two servers and made a cluster active/passive mode. Clustersuite needs fencing devices, in compatibility list RSA and RSAII are listed but in this model this cards are removed.

Please any help for selecting the right choice for fencing??? RSAII are still compatible with this server model??

Best regards.

    Per http://www-03.ibm.com/systems/info/x86servers/serverproven/compat/us/xseries/x3650.html , the IBM 39Y9566 Remote Supervisor Adapter II Slimline is IBM approved for this server.

    The RSA2 card is only supported with the 3650, not the 3650M2 or M3.

    3650M2/M3 have a Integrated Management Module (IMM) which replaces/improves on the RSA2 functionality and is embedded within the system board (IMM=BMC+RSA2). Note: Remote Presence is enabled via a orderable HW Key option.

    Hi

    My name is Charanjit I was doing the googling and found this post relevent for addressing my issue. My issue
    is I have IBM x3650 M3 server on which I have installed the RHEL 5.5 32 bit OS and deployed the RHEL cluster suit I have used IMM as its fencing device in a cluster in ipmi option. But now issue is if my active server gets fail my passive node unable to fence the active node in /var/log/messages it shows fence fail. If I execute fence_node same problem it shows that fence_ipmi fail to reboot the active node but if i execute fence_ipmi command for fencing active node then active node get fence. Please suggest what can be issue. I am attaching the cluster.conf file in this post.

    [4] - fence_rsa has been deprecated and replaced by IMM hardware, which utilizes fence_ipmilan.

    Hi there,

    from your cluster.conf file, it is apparent, you miss quorum disk, which definitely is problem in 2 node cluster, as for fencing you need to keep quorate.
