How to setup basic software iSCSI for VMware vSphere

This videos provides an overview of how to setup software iSCSI in VMware vSphere (VMware ESX 4 and VMware vCenter Server 4).

The steps are essentially the same for ESX 3.5 and vCenter Server 2.5 so this applies to those versions as well.

The steps are performed using the vSphere Client. For earlier versions of ESX/vCenter Server, you’ll use the VMware Infrastructure Client to perform the steps.

Announcing VMware KBTV

Our new video KB articles have been received so well by our customers that we have created a new blog just for video content.  The videos are great for how-to types of topics, or for doing white-board chats. Some folks are just happier having something shown to them rather than having to read through pages of steps.



So far we have about a dozen videos, but watch for this list to grow dramatically. You’ll want to subscribe to our RSS feed so you don’t miss anything.

ESXi 4.0 hosts not adding or reconnecting to vCenter Server

We've become aware of an issue where you can't add or reconnect an ESXi 4.0 host to a vCenter Server 4.0 or 4.0 Update 1. Specifically, the issue occurs if you remove and try to re-add the host or if you upgrade from vCenter Server 4.0 to vCenter Server 4.0 update 1. This is because the vCenter agent service does not install or upgrade on ESXi 4.0 hosts.

For up-to-date information on the issue, check out vCenter agent service does not install or upgrade on ESXi hosts (1016262).

The symptoms are:

  • vCenter Server reports the following error:

    Cannot install the vCenter agent service. Unknown Installer error

  • After the error, the ESXi host does not display in vCenter Server or stays disconnected.
  • All attempts to add or reconnect ESXi hosts to vCenter Server fail.

  • The /var/log/vmware/vpx-iupgrade.log file on the ESXi 4.0 host contains the error: 

    Acquiring lock /tmp/bootbank.lck
    Copying vpxa.vgz to /bootbank/vpxa.vgz
    Editing /bootbank/boot.cfg to add module vpxa.vgz

ESX 4.0 to Update 1 issue resolved in re-released Update 1A

We've released a new version of ESX 4.0 Update 1 that resolves the issue with the ESX 4.0 Update 1 install failing, timing out and resulting in the host entering an usable state.

The new version is called ESX 4.0 Update 1A.

You can find the new version on VMware Downloads.

For more details, see Due to a possible dead lock on rpmpd, upgrading ESX 4.0 to ESX 4.0 Update 1 can fail or time out and leave the host in an unusable state (1016070).

Timekeeping Revisited

Time keeping best practices for Windows VMs are something requested over and over, so today we updated an old KB article on the topic: Timekeeping best practices for Windows (1318).

There are two main issues to consider: correctly configuring time synchronization and avoiding excessive CPU and memory over commitment. Definitely worth a read if you virtualize Windows machines.
