Potential Problem with ESX 3.0.x and VirtualCenter 2.5
We are still running ESX 3.0.x and VC 2.0.x. I thought about upgrading vcenter first and then just upgrading the servers has time permits. But if there’s going to be odd issues like this, even if its only when you install some patches. I think I’ll try to put together a much shorter timeline to move to 3.5
Heads up—I’ve been alerted to a potential problem when using ESX Server 3.0.x with VirtualCenter 2.5. Quoting from this VMware KB article:
ESX Server 3.0.x hosts managed by VirtualCenter 2.5 must have their Host Agent (hostd) specially configured to work with VirtualCenter 2.5. This configuration is done automatically during the initial installation of the VirtualCenter Agent (vpxa). If an ESX Server patch is subsequently applied that includes the esx-hostd RPM package, like ESX Server patch 1002435, the patch replaces the existing Host Agent (hostd) configuration file (/etc/vmware/hostd/config.xml) and undoes vpxa’s changes. This reverting of the Host Agent configuration file breaks connectivity with VirtualCenter 2.5.

ESX3: Storage Health Check
You can easily check the health of your storage by looking under the /proc filesystem in the service console.
The directory /proc/vmware/scsi/vmhbaX/ where X refers to your HBA number contains virtual files which correspond to LUNs on that HBA. Using "cat" you can view the contents of these and check for cmdsAbrt (command aborts) and busRst (bus resets), these should both be zero indicating healthy storage connectivity. If either of these numbers are higher, especially bus resets, it is advisable to investigate for storage sub-system issues.
For example, to check LUN 0 on VMHBA0, which is LUN 0 on local storage, you would use:
cat /proc/vmware/scsi/vmhba0/0:0
You can obtain a summary of attached storage volumes from /proc/scsi/scsi again using "cat".

EMCWORLD was great, wish I could have met some of the other storage bloggers well I was there, maybe next year at Vegas.
I’ll be getting into navisphere Analyzer on Tuesday to look at some of the reports I learned about. I’ll also be dicussing EmailXtender and Avamar with my local EMC rep.

Windows Admin Script: Defrag Drives Based on Threshold
you should setup this script as a scheduled job to run after hours.
I’m going to start sharing some useful scripts that I use to automate many processes. Most of the ones I will share, I have gathered from the Internet and edited. Who knows just what I will share, but I can guarantee they can help you out with many system admin tasks!
The first one I will share is a Defragment script I have implemented to run every day on many of the XP workstations I manage. Defragmentation is a big problem if not taken care of every once in a while.
What is defragmentation? When a file is saved to the hard drive, it tries to keep everything in the same location (or cluster) Over the course of time files will be deleted, leaving blank areas between files. If you install another large program, the hard drive tries to fill the holes, thus breaking up the program storage block. This effects your system performance by as much as 200% since programs have to access more areas of the hard drive, just to run.
The script I will show below is based on a threshold of fragmentation. A drive will be defragmented only if it’s fragmentation percentage is determined to be equal to or greater than the FragThreshold value. You can edit to whatever you want.
REQUIREMENTS: The script has to be executed locally on only XP or Server 2003 systems and under account with permissions to defragment local fixed drives.
