  • 1.  Veritas DMP on AIX - Not showing all Paths

    Hi,
    We have Veritas installed on AIX 5.3 TL11, and DMP is not showing all the paths to hdisk.
    AIX server is connected to EMC array,and we have installed the ODM definition/PCM module as Veritas, which should disable MPIO.

    lspath shows that there are multiple paths to each hdisk.

    lspath -l hdisk11
    Enabled hdisk11 fscsi0
    Enabled hdisk11 fscsi2

    vxdmpadm listctlr all
    CTLR-NAME ENCLR-TYPE STATE ENCLR-NAME
    =====================================================
    vscsi0 IBM_VSCSI ENABLED ibm_vscsi0
    fscsi0 EMC ENABLED emc0

    Try uninstalling the EMC MPIO filesets. I think you've got a conflict. You'll probably want to rmdev and reconfigure the disks afterwards.

    I do not think that is the problem.We have another server ,where there is no EMC drivers. Veritas infact is asking to install vendor specific ODM definition or PCM module

    If you don't have any ODM driver installed, Veritas will manage the disks as if they are generic.

    The vendor specific ODM module is EMC.Symmetrix.aix.rte.

    EMC support is already built into the Veritas libraries so there shouldn't need to be anything other then the EMC ODM definition.

    I ran a very large AIX shop using the Veritas stack and we never had the MPIO filesets installed. You can take my advice or leave it but you are the one on the forum asking for help from people who have done this before.

    This is what we had to do, install the following two filesets. For AIX server connected to EMC Symmetrix or Clarion one can download the ODM definition from EMC, and install the respective filesets.
