VCS configuration for Solaris IPMP

Hi All,

I am trying to configure hme0 and qfe0 as part of IPMP group with virtual IP address being 10.0.0.200 which will migrate between node1 and node2.

Will this Solaris 10 IPMP configuration work? (a partial main.cf file):

group public_network (
                         SystemList = { node1 = 0, node2 = 1 }
                         Parallel = 1
                         AutoStartList = { node1, node2 }
 )
 
IPMultiNICB res_name2 (
                        BaseResName = public_network
                        Address = "10.0.0.200"
                        NetMask = "255.0.0.0"
  )
 
 MultiNICB res_name1 (
                       Device = { hme0 = 0, qfe0 = 1 }
  )

I want to use the virtual IP address for Oracle. I will be creating the Oracle resource group.

For the failover resource group, oracle-db, the partial listing of main.cf file will be:

group oracle-db (
            SystemList = { node1 = 0, node2 = 1 }
            AutoStartList = { node1 }
 )
 
 IP oracle-db_ip (
            Device = hme0
            Address = "10.0.0.200"
            NetMask = "255.0.0.0"
  )
 
 Netlsnr RP1_netlsnr (
           Owner = oracle
           Home = "/oracle/RP1/102_64"
           TnsAdmin = "/oracle/RP1/102_64/network/admin"
           Listener = LISTENER
  )
 
Oracle RP1_oracle (
          Sid = RP1
          Owner = oracle
          Home = "/oracle/RP1/102_64"
          Pfile = "/oracle/RP1/102_64/dbs/initRP1.ora"
  )
 
Proxy oracle-db-nic_proxy (
         TargetResName = res_name2
  )
 
Proxy oracle-db-cfs_proxy (
         TargetResName = cfs_online_phantom
  )


Regards,
Bruce

    couple of issues...

    1) you are using 10.0.0.200 twice ... i.e oracle-db_ip & res_name2 ... this is not correct / recommended , use it just in oracle group....

    2) multinicb resource should be used in a separate parallel group with a phantom resource (since NIC is persistent resource), see VCS bundled agents guide for reference...

    3) If u intend to use IPMP, u need to set UseMpathd =1 for multinicb resource, again refer VCS bundled agents guide for reference...

    Hi Gaurav,

       Thanks for your inputs. So should the main.cf file contain the following:

    group public_network (
     SystemList = { node1 = 0, node2 = 1 }
     Parallel = 1
     AutoStartList = { node1, node2 }
     )

     MultiNICB ipmp (
      UseMpathd = 1
      Device @node1 = { hme0 = "", qfe0 = "" }
      Device @node2 = { hme0 = "", qfe0 = "" }
      GroupName = vcs_ipmp
      )
     Phantom public_network_phantom (
      )
    group public_network (
     SystemList = { node1 = 0, node2 = 1 }
     Parallel = 1
     AutoStartList = { node1, node2 }
     )

    group oracle-db (
     SystemList = { node1 = 0, node2 = 1 }
     AutoStartList = { node1, node2 }
     )
     IP oracle-db_ip (
      Device = hme0
      Address = "10.0.0.200"
      NetMask = "255.0.0.0"
      )
     Netlsnr RP1_netlsnr (
      Owner = oracle
      Home = "/oracle/RP1/102_64"
      TnsAdmin = "/oracle/RP1/102_64/network/admin"
      Listener = LISTENER
      )
     Oracle RP1_oracle (
      Sid = RP1
      Owner = oracle
      Home = "/oracle/RP1/102_64"
      Pfile = "/oracle/RP1/102_64/dbs/initRP1.ora"
      )
     Proxy oracle-db-nic_proxy (
      TargetResName = public_network_phantom
      )
     Proxy oracle-db-cfs_proxy (
      TargetResName = cfs_online_phantom
      )
     requires group cfs online local firm
     oracle-db_ip requires oracle-db-nic_proxy
     RP1_netlsnr requires oracle-db_ip
     RP1_netlsnr requires RP1_oracle
     RP1_oracle requires oracle-db-cfs_proxy

    looks much better, however remove duplicate entry for group "public_network"......

    & I believe that IPMP config is setup correctly at solaris level...
