NAME

       opascpall

       (Linux)  Copies  files  or  directories  from  the current system to multiple hosts in the
       fabric. When copying large directory trees, use the -t option to improve performance. This
       option  tars  and  compresses the tree, transfers the resulting compressed tarball to each
       node, and untars it on each node.

       Use this tool for copying data files, operating system files, or applications to  all  the
       hosts (or a subset of hosts) within the fabric.

       NOTE:

       •      This  tool  can only copy from this system to a group of systems in the cluster. To
              copy from hosts in the cluster to this host, use opauploadall.

       •      user@ style syntax cannot be used when specifying filenames.

Syntax

       opascpall [-p] [-r] [-f  hostfile] [-h 'hosts'] [-u  user]
       source_file ... dest_file

       opascpall [-t] [-p] [-f  hostfile] [-h 'hosts'] [-u  user]
       [ source_dir [ dest_dir]]

Options

       --help

                 Produces full help text.

       -p

                 Performs copy in parallel on all hosts.

       -r

                 Performs recursive copy of directories.

       -t

                 Performs  optimized  recursive  copy  of  directories  using  tar.  dest_dir  is
                 optional.  If  dest_dir  is  not specified, it defaults to the current directory
                 name. If both source_dir and dest_dir are omitted,  they  both  default  to  the
                 current directory name.

       -h hosts

                 Specifies the list of hosts to copy to.

       -f hostfile

                 Specifies the file with hosts in cluster. Default is /etc/opa/hosts file.

       -u user

                 Specifies the user to perform copy to. Default is current user code.

       source_file

                 Specifies the a file or list of source files to copy.

       source_dir

                 Specifies the name of the source directory to copy. If omitted. is used.

       dest_file or dest_dir

                 Specifies the name of the destination file or directory to copy to. If more than
                 one source file, this must be a directory. If omitted current directory name  is
                 used.

Example

       # efficiently copy an entire directory tree

       opascpall -t -p /usr/src/opa/mpi_apps /usr/src/opa/mpi_apps

       # copy a group of files

       opascpall a b c /root/tools/

       # copy to an explicitly specified set of hosts

       opascpall -h 'arwen elrond' a b c /root/tools

       HOSTS='arwen elrond' opascpall a b c /root/tools

Environment Variables

       The following environment variables are also used by this command:

       HOSTS

                 List of hosts; used if -h option not supplied.

       HOSTS_FILE

                 File containing list of hosts; used in absence of -f and -h.

       FF_MAX_PARALLEL

                 When the -p option is used, maximum concurrent operations are performed.
