    Can you attach the install logs ? Was there any other error during installation ? Is it only the DMP installation or you are installing whole SF ? Did you do a rom --verify & confirm if package is installed without errors ?

    Try booting from CD/network in single user mode, Try to create a file (/etc/vx/reconfig.d/state.d/install-db), this file will make sure that vxvm doesn't start during boot time. Once system is booted

    paste below

    # cat /etc/system

    Try starting vxconfigd manually here

    # vxiod set 10
    # vxconfigd -m disable
    # vxdctl init <hostname>

    # vxdctl enable

    Let us know if you are able to start vxconfigd manually.

     

    In the mean time, something worth to look in

    dmp_native_support determines whether DMP will do multi-pathing for native devices.
    ideally the tunable should be set to on to have DMP do multi-pathing for native devices.

    After turning the tunable to off, are you able to get multipathing between luns ? Are you able to see paths & run a vxdmpadm stat & see if all paths are getting utilized.

    Hi Gauvrav,

    Thanks for the reply, I have managed to bring the server online.

    I need to install dmp alone as i will be using the LVM for disk management along with vcs,  so i installed DMP 5.1_SP1_RP2_RHEL6.x and took a reboot of the server. after reboot I updated the sfha rhel6_x86_64-5.1SP1PR2RP4 patches and did the vxdmpadm settune dmp_native_support=off.

     

    the server is coming online without issues, could you please tell me the parameter should be set on or it can be off, As i am not going to use VxVM.

    Please advise.

     

    Thanks and regards
