The following script generates a mapping of the Hitachi Multi-path
drives and provides all information necessary to identify a drive. The
information includes PVID, Location Code, WWN, LDEV Number, HDLM device
name, Hdisk device name, Major Number, and Volume Group.

#### Description: The purpose of this script is to provide a
#### mapping of the Hitachi SAN disks to show the various
#### identifiers associated with each disk. These identifiers
#### include:
####
#### PVID
#### Location Code
#### Hdisk Name
#### HDLM Name
#### WWN
#### LDEV Number
#### Volume Group
#### Major Number

This script generates HTML code containing the SAN Disk associations
for each SMART Instance Server. The information allows the AIX
administrator to boot an AIX host from a specific "rootvg" and to attach
SMART instances to that host.

#### Program: dlmfdrvhtml.sh

#### Description: The purpose of this script is to
#### obtain several parameters that identify the disk drives
#### associated with an AIX system. The drives may be
#### internal or exist on the SAN. The identification
#### parameters provide the AIX administrator with the
#### ability to boot the AIX machines from a selected drive,
#### and provide the ability to attach selected drives to an
#### AIX system.
