    Dear All,

    I have tried to deploy a webservice to the cluster, however, although the command by itself(without clusrun) runs well on each and every computers in the cluster, the clusrun does not work out. 

    1) clusrun /all hostname 

    The simple hostname command works out smoothly

    Microsoft Windows [Version 6.1.7601]

    C:\Windows\system32>clusrun /all hostname

    Please help.  It looks like the fileserver mapping can't be understood by the clusrun, but how could I make it understood correctly by clusrun. Thanks for your time.

    Yes, the process started by clusrun runs in session 0, and drive mappings such as the one you're using don't persist well across sessions and users. You can see whether your drive mapping is available within the clusrun command by running a command such as this:

    clusrun /all net use

    In your scenario, it's better to specify a UNC path instead of the drive mapping. e.g.

    clusrun /all xcopy /y \\fileserver\share\HPCExpress\PiCalcServer.dll "%CCP_HOME%\NxR2"

    Alternatively, if you absolutely have to use a drive mapping in your clusrun command, another solution might create the drive mapping as part of the command. This might look like the following:

    clusrun /all net use R: \\fileserver\share ^& xcopy /y R:\HPCExpress\PiCalcServer.dll "%CCP_HOME%\NxR2"

    Also, keep in mind that the %CCP_HOME% env var by default contains a terminating backslash. e.g.

    C:\>set ccp_home
    CCP_HOME=C:\Program Files\Microsoft HPC Pack 2008 R2\

    Regards,

    I had no idea you could run multiple commands in clusrun using '^&'.

    I assume this also works when you are trying to execute various commands in a node prep/node release task?

    Thanks!
