Rescan VMware vSphere Hypervisor (ESXi) using PowerCLI simplified

Tweet
While preparing some disaster recovery (DR) tests, I had to add and remove a couple of LUNS from several ESX hosts in different clusters. Doing so,  I had to rescan a lot of host bus adapters (HBA) several times. As I hate doing repetitive tasks in a graphical user interface (GUI), I always find myself [...]

vCloud Director offerings are coming

Tweet
During VMworld Europe 2010 in Copenhagen I had the opportunity to have a glimpse of the VMware vCloud Director (vCD). While back in 2009 VMware was only still introducing the foundation for cloud computing by releasing vSphere 4, now just one year later, they actually did it and provide the software to actually enable cloud [...]

Collect VMware ESX Host PCI Device Information

Tweet
Whenever you need to install a new box with ESX, there’s the struggle with matching physical ports to VMware devices. Which network adapter becomes vmnic0?, Which hostbus adapter becomes vmhba1?, etc. Especially when you have a lot of network adapters this can be confusing and you can’t connect to the device over the network unless you [...]

PowerCLI: Disable/Enable HA and DRS

Tweet
Before upgrading my Virtual Center 2.5 server to vCenter Server 4.0, I decided to temporarily disable HA and DRS. This is just a precaution taken to avoid waiting for cluster reconfigurations right after the upgrade. Because I hate doing things more than once by hand, I used PowerCLI for this.
Although no rocket science you can use the [...]

How sure is your backup?

Tweet
Everybody backups their environment, but how many do actually test if the backup can be restored? When you do, you know how time consuming this process is and even when you do a test restore, you are actually only testing that particular backup. You can’t possibly test every backup in your environment.

Unattended upgrade of HP mgmt agents – Part 2

Tweet
It’s been a year since I blogged about my script to perform an unattended upgrade of the HP management agents 8.1.1 on ESX 3.5 U3. After HP upgraded their management agents to version 8.2.0 some things changed. The installation procedure is now a 2 step process. First there’s a PreInstall_Setup.sh script which modifies some startup [...]

Critical 2009 last-minute ESX3.5 patches

Tweet
I just noticed that VMware released a couple of critical ESX3.5 fixes on December 29th, shortly after releasing ESX3.5 Update5 on December 3rd. Wading through the patch details I stumbled upon some severe issues addressed by the ESX350-200912401-BG patch. I quote some issues that caught my eye: 

ESX hosts might get disconnected from VirtualCenter Server. This issue [...]

How to force a login on a QLogic HBA

Tweet
When running some storage test on an ESX 3.5 environment lately, I ran into a problem where a dead storage path disappeared after a rescan. While this was as expected, the storage path didn’t return after fixing it in the SAN and running a rescan again. After a reboot of the ESX server, the new [...]
