Issues in Tapelibrary using robtest

I've tried to run robtest (Symantec net backup 7.5.0.6)  and got this message

    Seems the device path has disappeared or changed.

    What does the output of this command show?

    volmgr\bin\scan -changer

     

    If the robot no longer shows under scan you have an issue with the robot being presented to the OS - check the cabling/zoning and rescan the devices.

    You will need to delete the robot and re-add it once you get it back, or manually change the device path (deleting and re-adding is so much easier)

    Also check for ghost devices since you will be removeing and readding in the device manager: TECH93292

    To identify and remove the ghost devices from the Windows Device Manager, do the following:

     
    1.  From the command prompt on the problem media server, run:
     
    C:\>set devmgr_show_nonpresent_devices=1
     
    C:\>start devmgmt.msc 
     

     
    2.  Then, select View from the drop down and select to Show Hidden Devices.
     

    At this point, any ghost tape devices will be seen with lighter, transparent icon and can be removed.  This is done by right-clicking the ghost tape device and selecting "Uninstall".  A reboot of the machine should be performed following this action.

    The device is visible. Rerun your device configuration as suggested above. Then try robtest again.

    Did you delete the robot from within NetBackup? If so, delete it again from NetBackup then delete from devices in Windows, then rescan to re-detect the robot, then run tpautoconf -a from volmgr\bin to rediscover it within NetBackup

    then run robtest again. what is the result?

    I agree with above advice - the device path for the robot should not be the serial number.

    So, best to delete existing robot config and re-add from the Device Config wizard.

    Please ensure that Persistent Binding is in place at HBA level to prevent OS from losing connectivity to devices.
