| Announcing the start of development of Configuring and Managing Complex
OpenVMS Cluster Environments.
This project will create a five day lecture lab that will teach MCS
service delivery engineers and customers how to configure, install,
upgrade, and manage complex OpenVMScluster environments. These
environments are complex because they have multiple connections via
similar and or different interconnects and or may include both AXP and
VAX systems. The target audience for this course is:
- MCS engineers delivering remote remedial support for OpenVMS.
- MCS engineers delivering installation and start-up services
for OpenVMS.
- OpenVMS System Managers who manage complex VMScluster
environments.
While this course is being funded by Multi Vendor Customer Services
(MCS), it is also being made available to customers and the planning
has included customer instructor input. It is a follow on to System
and Network Node Management III, they are capable of supportind and
managing ethernet clusters and simple CI configurations. There is no
training on more complex environments such as multi-rail NI, complex
CI, distributed FDDI, mixed interconnect, or mixed architecture
(AXP/VAX) clusters. These technologies are the stepping-stone into the
cluster of the future. This course will obsolete the VAXcluster System
Management course.
The following is a high level topic outline, the order is subject to
change, more depth will be added to some sections:
I. VMScluster Architecture
A. Understanding the architectural/protocol layers
components of the layers (CNXMAN, SCS, Datagrams,
VAXports, class drivers, MCSP, TMSCP, multi-LAN.)
B. Overview and limitations of cluster media (CI [incl.
tickcount=10 & RDP], NI, multi-NI, DSSI, FDDI) and
adapters including limitations.
C. Overview of FT clusters
II. Archictectural considerations & config management:
A. Complex CI configurations
B. MI Configurations
C. Mixed Architecture Configurations
1. Why run mixed architecture VMSclusters
2. VMScluster software features in OpenVMS AXP
Version 1.5
3. Mixed VMScluster configuration rules and constraints
a. Common vs. multi system disk
4. Performance issues in configuring MA clusters
5. VMScluster management support such as:
a. How to create common system command procedures
b. How to tell AXP or VAX executables
c. Future expansion to full AXP clusters
6. Upgrading to a Mixed Architecture Cluster
D. Distributed configurations
1. Multi-datacenter/FDDI
2. Clustering through bridges, etc.
E. VMS Clusters as multivendor servers
connectivity management (in a
multi-vendor environment, w/ OSs, NOSs (netware, banyan,
pathworks-decnet), routers, bridges etc).
1. Number of bridges and acceptable delay
III. Design & implementation
thorough Quorum (for two node only) planning discussions -
differences for CI/DSSI vs NI-only, dual/tri/quad host
strategies, restrictions
IV. VMScluster storage
A. storage management (managing disk drives in a cluster -
where to place files for load balancing and
accessibility; RAID; controller issues, disk issues.
B. Striping, shadowing, and shadowed stripe sets
V. Cluster security
Multihost security in a non-homogen. environment (i.e.
not just the VAXen & AXPs, but issues which come up with
the cluster as a client/server host, and how Macs, PCs,
VI. Network considerations incl. phase V long names
VII. Advanced NI node topics
A. Satellite booting sequence, troubleshooting booting.
B. NI cluster specific performance issues.
C. Staged booting
D. NI system disk, striping, shadowing

I am working fast and furious on chapter 7 as we speak. It should be
finished by Friday.
The Prototype teach is to be held in Atlanta the week of May 16. John
Grundhoefer will be the instructor.
Comments received by May 23 will receive full consideration. After
that I will do the best I can. I am disappointed that this very
important course has received so little comment.
I would like to emphasize again that this is not just an update of the
old cluster course. This is a very new course that is heavy on
concepts.
Please post comments in this notes file or send them to SUPER::TARRY.
Chapter 1 Introduction to clusters and the SHOW CLUSTER utility
Chapter 2 SCS, Interconnects,
Chapter 3 Storage options, disk serving, boot servers
Chapter 4 Quorum, Distributed lock manager, State transition
Chapter 5 Configuring for availability, scalability and performance,
Business Recovery Server
Chapter 6 Installing OpenVMS and using CLUSTER_CONFIG.COM to build
a VMScluster. (Mostly review)
Chapter 7 Managing a VMScluster system, queue manager, DECamds,
VAXsimPlus, and more

| The prototytpe edition of the instructor manual has been posted
in the review directory. It includes:
lecture materials chapters 1-7
lab exercises 8
test 9
glossary 10
The directory is:
SUPER::$1$DUA6:[IDC$REVIEW.VMS_CLUSTER_V6]EY-Q154E-INSTRUCTOR-PILOT.PS
The prototype teach starts May 16 in Atlanta with John Grundhoefer as
the instructor.
Changes will be made to the files the following week. All comments
must be received by May 23 in order to be considered for this rev of
the course.
The next task is to post the overheads.
There will be at least one collection on security added to the course
after the prototype teach.
This is not just an update of the old course. Instructors should
expect to spend some time preparing. Students should have completed
sysnet I,II, and III before taking this course. There is some
duplication of materials, but not much.
Written exercises are included at the end of the chapter. These
exercises are part of the course and not just a test of reading skills.
Please devote some time to the exercises.
There are 12 lab exercises. You will probably have to be selective
about which ones you perform.
Some text materials are marked as (Optional). Optional materials are
explained in the "About This Course". Materials are optional
because they are:
Review materials presented for easy reference
Beyond the scope of the course
Reference materials needed for the lab exercises
For example, there is a section that lists and defines in tables all
the fields displayed by the SHOW CLUSTER utility. Students will need
this material to use the utility, but they really don't need for the
instructor to read it all to them. The new course format disallows
appendices.
In another example, XOR parity is explained. This is beyond the scope
of the course, but students can read it on their own.
