prty. The lowest priority is 0.
Depending on the system configuration, priorities may or may not be honored.

it not be found online (i.e. stage). Depending on the system configuration,
staging may or may not be honored.
requests that the file be copied into the cluster should
it not be found on the same server as the first file in the specified list of
files When the file is copied it is co-located with the first file in the list
of files, if sufficient space exists on the target server. Depending on the
system configuration, co-location may or may not be honored.

OPERANDS
target

where the prepare is to occur. If the prepare is to occur on more than one
redirector, specified each one separated by a comma.
are the files to be prepared. Specify one or more files
separated by a space. to occur. If the prepare is to occur on more than one
redirector, specified each one separated by a comma. If fB-f is specified, you
need not specify any files on the command line. Files specified on the command
line are always processed first.
NOTES
Unless the -s or -S option is specified, file
preparation merely seeds the redirector's location cache. This allows the
look-ups for prepared files to progress much faster in the future.
