Help to create a share DG

Hello

I am new in VCS using the CVMVolDg concepts.

Please take a look at my steps to create my share disk group and then present it to VCS.

Before I update my production VCS, could anyone point any possible mistakes ?

1) In my VCS Master Node (vxdctl -c mode), I create a dg and turn it to a share using (vxdg deport arch1dg / vxdg -s import arch1dg)

2) Listing the dgs:

svmediador2:/# vxdg list
NAME         STATE           ID
bgw1dg       enabled,shared       1338943751.50.svmediador1
arch1dg      enabled,shared       1351182830.67.svmediador2
ora1dg        enabled,shared       1338925017.17.svmediador1
 

3) After this, was created the Volume -  vxassist -g arch1dg make vol01 100g

4) Then, make the FS - mkfs -F vxfs /dev/vx/rdsk/arch1dg/vol01

5) Testing, I can mount the filesystem in both VCS cluster nodes, but not at the same time. One mount at a time.

6) Configuring this arch1dg at VCS, enabling to mount at the both nodes, some parts of my main.cf is:

6.1) INSERTING THE ARCH1DG IN THE CVM GROUP:

group cvm (
    SystemList = { svmediador1 = 0, svmediador2 = 1 }
    AutoFailOver = 0
    Parallel = 1
    AutoStartList = { svmediador1, svmediador2 }
    )

    CFSfsckd vxfsckd (
        ActivationMode @svmediador1 = { bgw1dg = sw, arch1dg = sw, ora1dg = sw}
        ActivationMode @svmediador2 = { bgw1dg = sw, arch1dg = sw, ora1dg = sw}
        )

    CVMCluster cvm_clus (
        CVMClustName = MediatorCluster
        CVMNodeId = { svmediador1 = 0, svmediador2 = 1 }
        CVMTransport = gab
        CVMTimeout = 200
        )

    CVMVxconfigd cvm_vxconfigd (
        Critical = 0
        CVMVxconfigdArgs = { syslog }
        )

    cvm_clus requires cvm_vxconfigd
    vxfsckd requires cvm_clus

6.2) INSERTING MY NEW ARCH1DG IN THE ora_DG GROUP:

group ora_DG (
    SystemList = { svmediador1 = 0, svmediador2 = 1 }
    AutoFailOver = 0
    Parallel = 1
    AutoStartList = { svmediador1, svmediador2 }
    )

    CFSMount cfsmount4 (
        Critical = 0
        MountPoint = "/var/opt/mediation/ora"
        BlockDevice = "/dev/vx/dsk/ora1dg/vol01"
        NodeList = { svmediador1, svmediador2 }
        )
    CFSMount cfsmount13 (
        Critical = 0
        MountPoint = "/oraarch"
        BlockDevice = "/dev/vx/dsk/arch1dg/vol01"
        NodeList = { svmediador1, svmediador2 }
        )

    CVMVolDg cvmvoldg4 (
        Critical = 0
        CVMDiskGroup = ora1dg
        CVMActivation @svmediador1 = sw
        CVMActivation @svmediador2 = sw
        )

    CVMVolDg cvmvoldg13 (
        Critical = 0
        CVMDiskGroup = arch1dg
        CVMActivation @svmediador1 = sw
        CVMActivation @svmediador2 = sw
        )

    requires group cvm online local firm
    cfsmount4 requires cvmvoldg4
    cfsmount13 requires cvmvoldg13

6.3) Oracle1 Group REQUIRES THE ora_DG

group Oracle1 (
    SystemList = { svmediador1 = 1, svmediador2 = 2 }
    AutoStartList = { svmediador1 }
    )

    IPMultiNIC Oracle1_IP (
        Address = "192.168.4.98"
        NetMask = "255.255.255.0"
        MultiNICResName = MultiNICA
        IfconfigTwice = 1
        )

    ORACLE bgw (
        )

    Proxy Oracle1_NIC_PROXY (
        TargetResName = MultiNICA
        )

    requires group ora_DG online local firm
    Oracle1_IP requires Oracle1_NIC_PROXY
    bgw requires Oracle1_IP

7) Did I forget anything ? This mess is going to work?

Thanks a lot
