Abstract

A software program is disclosed that automates cloning of Volume Groups (VG) for IBM's Advanced Interactive eXecutive(AIX) operating system. The program consists of three (3) Korn Shell script files which read the existing Volume Group (VG), Logical Volume (LV) and filesystem configuration of a running AIX system and produces a script which would duplicate that VG, LV, and filesystem arrangement on another AIX system with a similar disk configuration. The AIX system VG (rootvg) is specifically excluded from this processing.

AIX Volume Group Cloning

   A software program is disclosed that automates cloning of
Volume Groups (VG) for IBM's Advanced Interactive eXecutive(AIX)
operating system.  The program consists of three (3) Korn Shell
script files which read the existing Volume Group (VG), Logical
Volume (LV) and filesystem configuration of a running AIX system and
produces a script which would duplicate that VG, LV, and filesystem
arrangement on another AIX system with a similar disk configuration.
The AIX system VG (rootvg) is specifically excluded from this
processing.

   The disclosed program provides AIX System Administrators
with the capability to clone like systems by building the first and
replicating it onto the others.  It also serves as a key component in
a disaster recovery plan for AIX systems (such as RS6000/Scaleable
Processors) that are usually backed up and restored via a network
backup facility (such as Adstar Distributed Storage Manager (ADSM))
rather than standalone tape.  ADSM requires the containers, i.e. the
VG, LV, and filesystem configuration to be created before customer
data can be restored.

   The names and functions of the disclosed program modules
are:
  -savelv.ksh: reads the VG, LV, and filesystem configuration on
   the running system and writes a temporary data file.
  -rstorlv.ksh: reads the above temporary data file and writes a
   Korn shell script that contains the commands to recreate the
   VG, LV, and filesystem configuration.
  -savevg...
