####
#### Description: The purpose of this script is to map the
#### disks from a VIO server to their respective virtual SCSI
#### slot numbers, virtual adapters, and LDEV numbers.
####
#### This script is intended to be run on a VIO server in the
#### "oem_setup_env" environment. The output from this script
#### is a table of information containing the name of the VIO
#### server, hdisk name, virtual adapter name, virtual slot
#### number, and the SAN LDEV ID.
