What is the vSphere Web Client?

What is the vSphere Web Client?

  • This is a funky new feature in vSphere 5
  • An alternative to using the vSphere Client and a web-based interface to vCenter or a VMware ESXi host
  • Supports Firefox and IE Browsers on multiple O/S platforms (Windows and Linux)
  • Customisable Interface
  • Advanced Search Functionality
  • Partners and Users can add features and capabilities
  • Requires Adobe Flash Player

What can it be used for?

  •  Managing VMs
  • Creating VMs
  • Performing VM operations
  • Configuring VM Resources
  • Viewing all vSphere objects
  • Performing basic health monitoring
  • Supplying a remote console
  • Managing vSphere apps through the web

Where do you install it from?

The only difference between installing this to the vSphere Client is selecting an HTTP and a HTTPS Port. By default the HTTP and HTTPS ports are 9090 and 9443 although be careful using 9443 as this is used as a storage I/O Port by VMware. Possible conflict

Installation

  • Before you can connect to a vCenter Server Instance, you must register the vCenter Server Instance.
  • Select Start > Programs > VMware > VMware vSphere Web Client > vSphere Administration Application and click Register vCenter Server

  •  Use this tool to register one or more vCenter Instances. This tool cannot be run remotely. The User must have Admin rights to the vCenter Server Instance

  • Ignore the Client Certificate warning
  • The next screen is the final screen showing you are configured.

  • Open a Web Browser window and type in the URL HTTP:vCenterSever:9443/vSphere-client
  • Put in Server, Username and Password

This Service runs under a service called vCenter Inventory Service – Always make sure this is running or you may get an error when you connect.

Unable to add new LUNS on VMware 4.1 U2

Problem

This week we have upgraded our hosts to VMware ESXi 4.1.0, 582267. Our storage guy has given us 2 x 2TB LUN’s but I was unable to add them as per screen-print below. Previously he has created 2TB LUNs and these have been fine

Unable to read partition information from disk

Solution

It seems Update 2 enforces the maximum LUN size, which is 2TB minus 512 Bytes with vSphere 4.x. Depending on the storage system, 2 TB could be either 2.000 GB (marketing size) or 2.048GB (technical size). The above mentioned maximum relates to the technical size, so with the storage system you have, you may need to configure 2.047GB max.
