VSICM55 - Slide 02-32 - Viewing ESXi System Logs



Wrong:

The third and fourth paragraphs in slide notes state:

In vSphere 5.5, all log messages are generated by syslog, and messages are logged to either a local log server, one or more remote log servers, or both. A given server logs messages from more than one host. Log messages can be remotely logged by using either SSL or TCP connections.
With vSphere 5.5, you can configure log messages from different sources to go into different logs for more convenience.
Correct:

Stated as it is shown above, the sentences seem to suggest that syslog support has been introduced in vSphere 5.5. Instead, both local and remote syslog facilities has been introduced in vSphere 5.0.

Installing the vCenter Operations Manager 5.x vApp when DRS is not available

In my role as a VMware Certified Instructor I often find myself warmly recommending my students to try vCenter Operations Manager in their environments, either test and development or production ones. When I do so, I'm fully convinced they can very much benefit from the precious informations they can get out of it, regardless they are an SMB, a Corporate or a Service Provider.

During a recent course, in Oslo (NO), one of the attendees mentioned a strange issue he had when he tried to deploy vCenter Operations Manager:

The operation is not supported on the object.

It turned out to be a problem related to the lack of Distributed Resource Scheduler (DRS) support when deploying the vCenter Operations Manager vApp within a cluster.

 

Background Informations

vCenter Operations Manager is distributed as a vApp - using the Open Virtualization Appliance (OVA) format - that you can import and deploy to a virtualization platform, such as vSphere. A vApp has the same basic operation as a virtual machine, but can contain multiple virtual machines or appliances. The same vApp exists for the Foundation (available in vSphere 5.1), Standard, Advanced, and Enterprise Editions.

vCenter Operations Manager architecture consists of two virtual machines:

  • The UI VM allows you to access the results of the analytics in the form of badges and scores using the Web-based application for the UI VM. It also allows you access to the Administration Portal in order to perform management tasks.
  • The Analytics VM is responsible for collecting data from vCenter Server, vCenter Configuration Manager, and third party data sources, such as metrics, topology, and change events. Raw data is stored in its scalable File System Database (FSDB).

 

VMware Knowledge Base

According to the VMware Knowledge Base article number 2013695 explaining the issue mentioned above, since VirtualCenter Server 2.0 (back in 2006), DRS is required for the deployment of a resource pool in a cluster. DRS is also used to place the virtual machines in a vApp within a cluster. Hence, even if deploying vCenter Operations Manager 5.x on a standalone ESXi host does not require DRS, deploying it on a cluster does require DRS.

As vSphere DRS is only available on vSphere Enterprise and Enterprise Plus editions, it is now clear that deploying vCenter Operations Manager 5.x in any other vSphere license edition will require some additional step.

 

Resolution

To deploy vCenter Operations Manager 5.x in a vCenter Server environment with an Essentials Plus or Standard cluster of three ESX hosts:

  1. Remove one of the ESXi hosts from the cluster so that it resides directly under the parent datacenter.
  2. On that ESXi host, deploy the vCenter Operations Manager vApp, specifying static IP addresses.
  3. Power on the vApp before moving the host back into the cluster to ensure IP settings are picked up.
  4. License the solution in vCenter.
  5. Move the ESXi host with vCenter Operations back into the cluster.

Why "myCourseware Corrections"?

"myCourseware Corrections" is an idea based on a recurrent aspect we all face - as either VMware Certified Instructors or class attendees - every time a new course is released: there might be typos, errors and inaccuracies which are unintentionally introduced with the new course materials or carried over from previous courseware revisions.

As this can be sometimes a hassle for trainers, not to mention the misleading understanding engendered in students' perception, I thought it would have been useful to have a reference place where to find corrected and updated notes, plus complementing detailed informations to further integrate the required knowledge.

It is not my intention to claim these pages will become your ultimate source of truth, yet - having already done the majority of this work for myself - I would like to share the outcome with those who might be interested in using it as a support when prepping their VMware certification exam or when teaching.

As a courtesy, since we ALL make mistakes, if you find any courseware correction I'm suggesting here to be inaccurate or incomplete, please drop me a line: I'll be very happy to accept your suggestions, correct my errors and credit your feedback.

VSICM51 - Slide 14-40 - Managing vCenter Server Appliance Services



Wrong:

The second paragraph in slide notes state:

The embedded database is a DB2 Express database.
Correct:

The IBM DB2 Express database - originally deployed in vSphere 5.0 - has been soon replaced by PostgreSQL.

Versions 5.0.1 and 5.1 of the vCenter Server Appliance use PostgreSQL for the embedded database instead of IBM DB2, which was used in vCenter Server Appliance 5.0.

VSICM51 - Slide 14-25 - vCenter Server Installation Wizard



1. Wrong:

In the slide notes, the unordered list item "SYSTEM account or user-specified account", which states the vCenter Server service account requirements, is incomplete.

Even if you do not use Windows authentication for SQL Server, you might want to set up a local user-specified account for vCenter Server. The only requirement is that the user-specified account must be an administrator on the local machine.
1. Correct:

Actually, the domain user account permissions pre-requisites are three:

  • Member of the Administrators group.
  • Act as part of the operating system.
  • Log on as a service.
1. Source:

vSphere 5.1 Documentation Center.



2. Wrong:

In the slide notes, the unordered list item "vCenter ports", which lists the network ports required by vCenter Server, is incomplete.

2. Correct:

The most up-to-date list of the required ports for vCenter Server can be found in the online documentation following the link provided below (the page also provides a link for the documentation page listing ports required by the vCenter Server Virtual Appliance).

VSICM51 - Slide 14-22 - Before Installing vCenter Server



1. Wrong:

The second item of the unordered list in the slide notes state:

Make sure that the system that you use for vCenter Server belongs to a domain and not a workgroup. If the system is assigned to a workgroup, vCenter Server is unable to discover all domains and systems available on the network when using such features as Guided Consolidation.
1.a. Correct:

vCenter Server can belong to either an Active Directory Domain or a Workgroup, in which case the documentation has a warning:

If the system that you use for your vCenter Server installation belongs to a workgroup rather than a domain, not all functionality is available to vCenter Server. If assigned to a workgroup, the vCenter Server system is not able to discover all domains and systems available on the network when using some features.
1.a. Source:

vSphere 5.1 Documentation Center.


1.b. Correct:

According to vSphere 4.1 Release Notes:

VMware vSphere 4.1 and its subsequent update and patch releases are the last major releases for VMware Guided Consolidation.

As such, VMware vCenter Guided Consolidation is no longer supported in vSphere 5.x, hence the above list item from slide notes is not applicable to this release.

1.b. Source:

VMware vSphere 4.1 Release Notes.



2. Wrong:

Another typo, in the third item of the unordered list in slide notes, messes up with the embedded database version:

Create a vCenter Server database, unless you want to use SQL Server 2008 Express, the default vCenter Server database.
2. Correct:

As already stated for slide 14-20, the correct version of the embedded database is SQL Server 2008 R2 Express.
