VMware vSphere Client for Ipad now avaible

Since VMworld San Francisco 2010 we are waiting for this nice app for the Ipad. VMware today released this app via the iTunes store for FREE (Direct Link), just as the VMware View Client for IPAD (Direct Link).

 What are the features available in this app?

  • Search for vSphere hosts and virtual machines in your vSphere environment
  • Monitor the performance of vSphere hosts and virtual machines
  • Manage virtual machines with the ability to start, stop and suspend
  • View and restore your virtual machines’ snapshots
  • Reboot vSphere hosts or put them into maintenance mode
  • Diagnose vSphere hosts and virtual machines using built-in ping and traceroute tools

 

 

 

 

 

What is required for this app to be able to manage your vCenter?

  • vCenter Mobile Access (vCMA) virtual appliance available from the VMware Labs: http://labs.vmware.com/flings/vcma (Now supports SSL)

    NOTE: This app is available as is, with community support.

  • Network connection to the vCMA virtual appliance; can use built-in VPN client
  • VMware vSphere and VMware vCenter Server

Look at my blog entry to see how to setup the vCMA : limited-vsphere-management-using-a-mobile-device

An overview of the architecture

(Limited) vSphere management using a mobile device

On the VMware Labs website you can find a free appliance that can give you limited access to the management tools available in vSphere vCenter. The appliance is called vCMA or vCenter Mobile Access.

How to install?

  • Go to the vmware.com/labs website and download vCMA as a OVF. Jump to site
  • Extract the zip file that contains the OVF.
  • In vCenter, go File – Deploy from OVF and point to the extracted OVF file.
  • Once deployed, you can start the VM.
  • After the VM is started, there are 3 options to change settings
    • Using the menus on the console (to set network, timezone, login in to the command console)

    • Using the web interface https://vcma-host-or-ip:5480

       

    • Or using the command console. (use login in first screen)

       

      • By default the root account has as password vmware (remember the console is by default in qwerty)

 

Special configuration settings to thing about!

  • Set the IP to a fixed address
  • Enter the DNS servers
  • Change the default hostname and domainname. (http://communities.vmware.com/message/1335001)
  • Change the root default password using the passwd, in the command console

How to use?

  • It is very easy to start using this app.
  • Open a browser (on you PC or mobile device)
  • Point to http:// vcma-host-or-ip/vim (the folder /vim is needed and I hope VMware will change this in a next release)
  • Enter the vCenter server name and the userID and password you normally use in the vcenter.
  • Now you can do some functions like
    • vMotion
    • Edit settings of a VM
    • Change Powerstates of a VM
    • Etc, install and discover.

Website was gone for some hours

The upgrade to wordpress 3.05 did go as smooth as it should be.  Website was completely corrupt.  and as each good IT guy I had a backup (NOT).  Copied all files that were still available, copied the WP 3.05 sources to my web host, then the config file back and everything in the contect dir (database was still ok) and lucky everything came up again.  Only updating the plugins and finished I was.

I also added the WPTOUCH plugin so the website has a nice view on the mobilephones as iPhone and Android.

Any good backup plugis available?   please recommend….

Dependent Hardware iSCSI Adapters

During the VMware vSphere ICM courses I sometimes get some questions on NIC’s that appear as a iSCSI card. What are they and how can they be used.

A definition from VMware (from the SAN Introduction page)

Dependent Hardware iSCSI Adapter: Depends on VMware networking, and iSCSI configuration and management interfaces provided by VMware. This type of adapter can be a card that presents a standard network adapter and iSCSI offload functionality for the same port. The iSCSI offload functionality depends on the host’s network configuration to obtain the IP, MAC, and other parameters used for iSCSI sessions. An example of a dependent adapter is the iSCSI licensed Broadcom 5709 NIC.

Migrating Buslogic to LSI Logic SCSI controller in a Virtual Machine

When you use convertor to migrate a physical machine to a virtual machine you get a BusLogic Controller as SCSI controller. Following is tested on vSphere 4.1 with a Virtual Machine hardware version 7

In the Virtual Machine Settings you see this.

µ

In your device manager it is present as a VMware SCSI controller

If you want to change this to a LSI Logic SCSI controller because some application may need it like Trend Micro Deep Security – vShield, you have to follow steps below to get it working

Steps to convert

  • Install the latest VMware Tools.
  • Power down the Virtual Machine (try to use the shutdown so your OS is closed correctly.)
  • Edit Settings of the Virtual Machine and add a new disk (can be small because this will be removed afterwards). We cannot add a new SCSI controller without adding a disk.
  • When you add a new disk select a different SCSI-id then the existing SCSI Controller. First number in the ID is the number of the SCSI controller.

     

  • When the disk is updated, the type of the SCSI controller must be changed.

     

  • When the configuration is updated, you can restart the VM
  • In your device manager you now see 2 types of SCSI controllers

     

  • When you see the LSI logic SCSI controller you can shut down the VM again. Then will remove the just added disk and change the type of SCSI Controller 0

     

  • When this is finished you can restart the Virtual Machine
  • After starting the Virtual Machine you see that new hardware is found, now you need to reboot once more. (Last time to reboot).
  • Now for best practices you need to remove all unused devices in you device manager. Therefor you need to start device manager using a special set parameter.
    • set devmgr_show_nonpresent_devices=1
    • devmgmt.msc

If you now select the SCSI and RAID Controllers, you will see some grayed-out devices. These devices should be uninstalled

  • Now you are done.

Clipboard Copy and Paste not possible in vSphere 4.1 Console connection

Hi,

I have done a lot of migration to VMware vSphere 4.1.  Everytime I bumb into the same issue: When I open a Console to a Virtual Machine and want to copy / paste some info into the Virtual Machine, it does not work anymore.

This because in vSphere 4.1 VMware has introducted one of the setting out of the Security Hardening guide for vSphere 4.0.  There ore 2 ways to bypass these settings:

  1. Use a RDP connection instead of a VMware Console connection to your Windows Machines and then the copy / paste still works (this is a best practice)
  2. Change the settings so copy / paste is allowed again.  Read this VMware KB Article

VSS issues when doing backups using VMware VDR

Hi,

During some consultancy projects @ SMB customers where we needed to install and configure VMware VDR to do some backups, we had some issues with Windows Machines and VSS. The result of the these errors with VSS was that the VDR backup jobs all failed.

Here some possible solutions (gonna try to keep the list up to date.)

  • VSS could not be started on a Windows 2003 server

We had to reregister all VSS DLL’s, restart the server and everything was working again. (check this)

VMware KB Articles about possible VDR / VSS issues.

Cannot create quieced snapshots if backup or system recovery applications are installed KB 1009558

Troubleshooting Volume Shadow Copy (VSS) quiesce related issues KB 1007696

A virtual machine can freeze under load when you take quiesced snapshots or use custom quiescing scripts KB 5962168

Because VDR is taking snapshots of your virtual machines this can also be a interesing KB

P2V issues with old hardware & IP addresses

Doing a P2V is very easy using the VMware Converter (Standard / Enterprise).  But after the machine has been migrated the P2V is not yet finished, we need to do some extra stuff.

  • Remove all hardware related software via add / remove programs (if possible) or disable the service.
  • Old unused devices should be removed using device manager after setting a special SET parameter (set devmgr_show_nonpresent_devices=1).  This can be done manually are using a script.
  • Update virtual hardware settings (CPU / Memory)
  • Enter the IP configuration on the new NIC.  (Can be automated)
  • Depending on the MS license you are using you maybe need to reactivate.
