Finding connection location for SSA pdisk definition.

ENVIRONMENT:
   AIX 4.1.5, 7133 SSA Subsystem
.PROBLEM:
   Customer is trying to find out how to get the connection address
   (A/B port plus hop count) for SSA disks.
.ACTION TAKEN:
   The "ssaconn" command will report this information.  This command
   is included as part of the SSA device drivers at 4.1.5.X and
   4.2.1.X.  With this, a script such as the following can be used.
   The script assumes that the commands are in the /usr/local/bin
   directory.  Usually, they will be located in the /usr/sbin
   directory.
.   *** NOTE ***
   The following script is provided on an as-is basis, and is not
   guaranteed; use at your own risk!
