vCenter Orchestrator (vCO) 5.5-Part-2-Executing Workflow using vCO

Manish Jha

In part-1 of this series we have configured the vCO settings and added vCenter Server where we will be executing the workflows from vCO.

In this part we will see how to use vCO to execute the workflows. A lot of pre-defined workflows are already integrated in vCO and you can import or create your custom workflows as well.

vCenter Orchestrator (vCO) 5.5-Part-1- Installing & Configuring vCO

Manish Jha

vCenter Orchestrator (vCO) is a cool product from VMware which allows you to create tasks and automated workflows which and be run directly within vSphere Web Client or the vCenter Orchestrator Client.

vCO brings automation to the next level and helps admins, engineers to orchestrate and integrate your cloud with the rest of management systems.

There are a number of pre-made workflows integrated in vCO to get you started. Almost any task that can be performed in vCenter can be automated through vCO. With the use of AD integration, API’s and other 3rd party plugin’s vCO becomes more powerful and can save a lot of time for the VMware admins.

Workflows can be anything from simple workflows that contain a single task to say create a virtual machine, to complicated workflows containing many tasks that might build an entire solution and integrate with 3rd party plugins.

vCO is included with vCenter Server and it’s free!  … Read More

Troubleshooting vDS out of sync issue

Manish Jha

Today when I booted my lab I saw some issues with one of the host and the summary page of host was showing the below error

“The vNetwork Distributed Switch configuration on some hosts differed from that of the vCenter Server.”

vds-0

The cause of this issue can be explained as follows:

When we install distributed switch and add hosts to the vDS a hidden switch is created on all hosts and a copy of  vDS database is copied to each host with information on the switch. This database is synched every 5 minutes.

vDS are created and managed from vCenter as it holds the management plane and the the part of vDS which get installed on per host level is called IO plane. So if ever vCenter Server is down it will not affect the VM traffic on the host and you will only loose management capabilities.

Selecting the vDS and navigating to host tab will show you a warning (under VDS status) that your host is out of sync.… Read More

vRealize Automation- Deploying Virtual Machines from self-Service Portal

Manish Jha

Finally we came to last post of this series where an end user will request a virtual machine for himself from the services he is entitled to.

In our last post Creating Entitlements we have created an entitlement for windows server 2003 and granted access to users manish@alex.local and alexhunt@alex.local. Lets see if these 2 users can request for a new virtual machine for themselves from the self-service portal and whether or not this request is completed.

An error occured while consolidating disks:msgs.fileio.locked

Manish Jha

Today while working in our production environment where our monitoring system has generated an alert for one of the vCenter server appliance. The alert was ” disk consolidation needed for server xyz”

On checking the vCenter VM status from management vCenter console I found that there as an yellow warning on the same and selecting the summary tab also confirmed the same error message about disk consolidation.

We are using EMC Avamar backup solution and my guess is Avamar failed to cleanup the snapshot which it took on the vcsa vm after backup.

I tried to consolidate the disk by going to snapshot manager for the vcsa VM and hitting consolidate button but it was failing with error “An error occured while consolidating disks:msgs.fileio.locked”

disk cond

I was not sure why this error is coming while doing consolidation and while searching for solution I came across this blog where the issue have been addressed.… Read More

vRealize Automation- Creating Entitlements

Manish Jha

Entitlements  allows you to grant users and groups access to Services and/or Blueprints as well as determine what actions they can perform with them. Entitlements offer a significant amount of flexibility in how you provide access to services through the catalog, who can access those services, what actions they can perform, and what is any approvals are required.

Entitlements are made up of three components. Services, Catalog Items, and Actions. You can choose to entitle complete Services which encompass all Items within the service or just select catalog Items. You can also determine what actions the users that belong to the entitle can perform against all the catalog items that are a part of the entitlement.

Within entitlements you also have the ability to assign approvals to Services, Catalog Items, and actions.

vRealize Automation- Creating a Service

Manish Jha

Self-Service catalog is a new way of managing Catalog Items. Service categories organizes catalog items into related offerings to enable end users to browse catalog items they needed in an easier and convenient way.

In vRA Blueprints are published which enables them to be assigned to users and groups through the catalog management components of the vRA Service Catalog. In earlier version of vCAC Blueprints were assigned to groups within the Blueprint itself.

To enable blueprints to be available in the catalog we first need a service that we can publish them to. Services are the containers that hold the actual catalog items that can be requested.

We must have at least one service in the environment to enable our catalog items against.

vRealize Automation-Create and Publish Blueprints

Manish Jha

What is A Blueprint?

Blueprints define the resources and attributes associated with the provisioning of a virtual, physical, or cloud machine. vRA supports several type of platforms as endpoint such as vSphere, vCloud, Hyper-V, XEN, Physical, Amazon etc so a unique Blueprint is needed per platform.

Blueprints are visible as Item to end users in Service Catalog from where they can request to provision a new virtual machine or applications etc.

In this post we will learn how to Create and Publish a vSphere Blueprint. To do this there are certain pre-requisites that need to be met.

Within the blueprint configuration there is a template picker that will allow you to pick form the available templates in your environment. In order for templates to show up in the template picker there are some items that need to be configured in the vCAC environment. You will need to have the following already configured:

  • vSphere Credential
  • vSphere EndPoint
  • Fabric Group (with the vSphere resources assigned)
  • Reservation

vRealize Automation-Create Business Group and Reservation

Manish Jha

What is a Business Group?

A Business group associates a set of services and resources to a set of users, such as a line of business, department, or other organizational unit. A business group is created within a tenant by the tenant administrator.

A business group can have access to catalog items specific to that group and to catalog items that are shared between business groups in the same tenant. Each business group has one or more reservations that determine on which compute resources, virtual machines that this group has requested can be provisioned. To request catalog items, a user must belong to at least one business group. A user can be a member of more than one business group, and can have different roles in different groups.

A business group must have at least one business group manager, who monitors the resource use for the group and often is an approver for catalog requests.… Read More

vRealize Automation-Creating and Configuring Fabric Groups

Manish Jha

Fabric and Fabric Groups

The Fabric groups are what enable you to provide access to resources from your physical infrastructure. Fabric includes all the computing resources that are discovered from the added endpoint data collection.

Fabric is organized into fabric groups and there can be multiple fabric groups with different purposes, for example you may assign clusters to different business groups within the enterprise to ensure performance.

Within a fabric group we add users or groups that are responsible for managing infrastructure resources and add the resources they are responsible for.

For example we may select clusters that are managed from vCenter and assign the user/groups that are responsible for managing those resources.

Fabric administrators are responsible for creating reservations on the compute resources within their groups to allocate fabric to specific business groups. Fabric groups are created in a specific tenant, but their resources can be made available to users who belong to business groups in all tenants.… Read More
