I got really really stuck into creating a custom VMware boot image today, I bought a cheap Adaptec card recently and I want to install VMware vSphere Hypervisor on it, apparently this is the only option.

Cut the long story, the VMware ISO will not detect the card and drives (although it supports and certified by VMware), that is why I need to create a custom boot disc.  Instruction from Adaptec shows that I need to use PowerCLI, some scripts and a bit of time to do that.  I tried and it doesn’t work!!!!!!!

Pick up the phone, call up the Adaptec support, quickly explain the situation and my first response is “Oh no, don’t use that, waste your time and it’s too hard”.  WTH, that’s the instruction “Black/White” written in the installation guide, but the technician tells me wrong….arggggg…..

Anyway, he knows what to do, below is the software and instruction that he highly recommend.


below is the link to the instruction

Creating a VMware 5.5 install CD for Adaptec Series 6-7-8 controllers

I guess it will work with other situations, but this seem to be an easier and promising tool to use.

Reclaim space from your Virtual Hard Disk on VMware Workstation

I am running a Windows7 VM on a 120GB SSD, and I am running it for Internet and converting video files.  One day I noticed that the disk is about to fill up, but hang on the usage only show 70GB of usage, where is the 50GB gone??

Then I realised that it is similar to its brother software VMware vSphere, it needs to manually claim the spaces back, however in a much easier way.

I am running VMware Workstation 9, and here is the link to it’s official explanation

Select the virtual machine in the library.
From the menu bar, select VM > Manage > Clean Up Disks.

Workstation calculates how much space can be reclaimed, and either the Clean Up Now button becomes available or a message appears, explaining why the command is unavailable.

Click Clean Up Now to start the process.

A dialog box reports the progress of the clean-up process.

Once after the clean up, my host shows 70GB of usage, plenty of free spaces left again.


ESX host grey out ~

Since last night, one of the ESX host in the cluster has became “not responding”, although all the VMs on it are still running, I just don’t know what will happen next.

From home, I logged in through Putty, and tried a few methods that found on Internet, still doesn’t resolve the problem.

This morning had a look at the console screen, it says some CPU Journal I/O error, not sure what it is yet, but looks like I will need to reboot the physical server to try fix it.
