In this video we demonstrate how to restart the management agents running on a VMware vSphere ESXi or ESX host.
For troubleshooting purposes, it may be necessary to restart the management agents on your ESXi or ESX host. This video tutorial goes through the steps that you will need to take in order to restart the management agents (mgmt-vmware and vmware-vpxa) directly on the vSphere ESXi or ESX host server.
We have a new video today which will be of interest to those of you wondering how VMware’s new Virtual SAN offering operates with other VMware solutions that you may have in your environment, specifically with vSphere Replication and Site Recovery Manager.
We look at how you can perform a planned migration of a set of virtual machines from a traditional storage infrastructure onto your virtual SAN cluster.
vSphere 5.5 has been released for all to download. We’re sure vSphere users are all eager to install a copy and start kicking the tires, and we’re just as eager to see that you get started on the right foot. With this in mind, we have created the following list of Knowledgebase articles that are brand new, or have been updated for vSphere 5.5 You’ll notice lots of best practices KBs here.
The first grouping contains absolute ‘must know’ information, the second grouping gets a bit more into details.
Fresh out of development today VMware has a new tool to help everyone with the implementation of custom certificates. The vCenter Certificate Automation Tool 1.0, will help customers update certificates needed for running vCenter Server and supporting components. This is primarily of interest to customers who use custom certificates either generated internally from Corporate CAs, or from public CA’s like VeriSign.
To add a little background information various components within vSphere and the vCenter platform use certificates for identifying themselves as well as for secure communication with external software entities (browsers, API clients). These can broadly be classified into the following categories:
Secure token Service Certificate – Certificate used by vCenter Single Sign On (SSO) for encryption tokens
Solution User Certificates – Certificates used by each solution to identify themselves as users to SSO
SSL Certificates – certificates needed for SSL communication for the UI and API layer
Host Certificates – These certificates are deployed in each ESXi host and used for secure vCenter to ESXi communication.
Note: The new certificate tool automates the updating of certificates in the management layer only (a, b, c above). This tool does NOT handle replacement of certificates in ESXi hosts.
The vCenter Certificate Automation Tool aims to automate the process of uploading certificates and restarting the following components within the vCenter Platform:
Some of you early adopters might have VMware vSphere 5.1 down pat by now, but we’re sure many of you are still trying to wrap your heads around all the new bits. Today we thought we’d highlight some really good documentation that is more than just your typical step-by-step instructions. These guides come in multiple formats such as HTML, PDF, EPUB and MOBI so you can download it to your device of choice and carry it around with you. We highly encourage you to check out the following:
Ever since vSphere 5.1 launched we’ve been getting a fair number of support calls about Single Sign On, or SSO for short. It is a requirement now, and many of you are getting caught on some aspect of the upgrade/implementation.
We don’t like our customers having to call into support. Not that we don’t love to hear from you, but we’d rather document how to deal with different issues and push the information out to you before you run into them. Then, you don’t have to waste time calling us!
Let’s start with two particularly important KB articles. These are classified as ‘Resolution Paths’. They walk you through an ordered set of steps in resolving a problem. You can read more about resolution path articles here.
This is the last video for today, but it is a special one indeed.
Note: This is a video of a Technology Preview.
VMware made some significant announcements around its storage direction at VMworld 2012 in San Francisco last month.
One of the announcements was about a new feature, Distributed Storage – basically the ability to take ESXi hosts with just local storage and build a distributed datastore across all hosts in the cluster. There are so many neat features attached to this, such as its scale out capability, the ability to have compute-only nodes in the cluster ,and the introduction of Storage Policy Based Management (SPBM) to define virtual machine storage requirements such as performance and availability in the form of a profile.
There is so much more to Distributed Storage than that, of course.
In this video, we have Cormac Hogan (Senior Technical Marketing Architect at VMware) discuss and demonstrate some interesting aspects of this new feature.
Cormac touches on:
Scale Out Storage
VM Storage Profile Creation
Provisioning a VM using Storage Profiles
We have worked with Cormac on several video tutorial projects in the past, so naturally we were delighted to work with him again on this really cool and interesting video topic. In fact, we are working on a few new video tutorials in coordination with Cormac relating to the VSA or vSphere Storage Appliance which we hope to make available for your viewing pleasure at some point in the next two weeks…so watch this space!
For now, you can get more information about this over at Cormac’s blog post.
For those of you heading to VMworld 2012 in Barcelona in October, Cormac highly recommends attending session INF-STO2192. For those of you who cannot make VMworld, Cormac highly recommends watching this video :-).
This presentation expands on the diagram provided in knowledge base article: VMware vSphere 5 Memory Management and Monitoring diagram (2017642). It provides a comprehensive look into the ESXi memory management mechanisms and reclamation methods, and also provides the relevant monitoring components in vCenter Server and the troubleshooting tools like ESXTOP.
