  1. strange issue (Media Server vs Device Manager)


    My environments is:
    Netbackup 5.1 w/ SSO
    1 Master Media Server, 4 Media Servers, all connected to a Quantum tape library
    via fiber optic cable.
    I've been having this problem with Media Servers losing their connection
    to the tape library which causes backup jobs to run endlessly and hangs Windows
    Device Manager. After this occurs the affected server can no longer connect
    to the library unless I reboot the server. I can't seem to correct the Windows
    Device Manager problem without the reboot.
    I've stopped the 4 NB services running on the host but noticed there are
    still several NB executables running....but I can't kill the processes.
    Does anyone have any idea how I can regain control of the server without
    rebooting?

    regards,
    JOE

    Did you set your drives for persistent bindings?

    Also, if they are hanging, did you look in Task Manager to see if any of
    the Veritas processes are still running? (usually start with bp...); you
    might have to use the kill commmand and kill by PID#.

    Hope this helps a bit...

    After stopping the 4 services on the affected Media Server I see bptm.exe,
    ltid.exe, oprd.exe. I can't stop any of these services...I tired using PSKill
    but I keep getting access denied.
    What do you mean by the "Kill" command?
    I'm checking into the persistent bindings.

    The clue here is that the Windows Device manager is also hung after
    this happens. Make sure that HBA and tape drive drivers are up to
    date. Make sure you are using persistent binding. Normally when
    Windows loses connection to a device it does not hang device manager.
    There may be something else wrong here.

    Jeff - Where do I confirm if I have "persistent bindings" configured?

    That is usually set in the HBA settings. Look at those first. They may
    also be called Static mappings.

    apparently these drives are not visible to ur hosts and it gets hang. review
    ur brocade zoning configuration. Hv u procured the sso option to use the
    same drive from a shared library ? if not, all connectd hosts will try to
    take the control of the drives and create such problem.

    I have a similar san configuration as yours-- a master and 4 medias, etc.
    I have been doing this---
    go to the nbu console and bring down all nbu services on all 5 servers.
    then open a cmd window on each of the five servers and do:
    tlist -t
    this gives the process id's of all the oprd executables
    then i use
    taskkill /f /pid

    after that is done on all 5 servers, i bring the services back up via the
    nbu console gui.
    after waiting a couple minutes or so for all master/media servers to sync
    up, the nbu functions usually act right again.
