VMware Converter 4.0.1 standalone fail at 1% with error: method.Summary

The Solution is taken from Vmware Knowledge Base,
When converting a Linux source to an ESX 4.1 host, VMware Converter 4.0.1 Standalone fails at 1% with the error: methodFault.Summary

Symptoms (Summary from Vmware KB)
  • When converting a Linux source machine to an ESX 4.1 host, VMware Converter 4.0.1 Standalone fails
  • The conversion fails continuously at 1%.
  • You see the error:
  • In the vmware-converter-agent.log file, located at C:\Documents and Settings\All Users\Application Data\VMware\VMware Converter Enterprise\Logs, you see the error:

    Failed to connect ISO to remote VM

Resolution (from  Vmware KB)
This issue occurs when using VMware Converter 4.0.1 Standalone with ESX 4.1 hosts because Converter Standalone version 4.0.1 is not compatible with vSphere 4.1.

To resolve the issue, try one of these options:
  • Install the latest version of VMware Converter from the vCenter Server installation media and use this to convert to an ESX 4.1 target. VMware Converter 4.3 supports conversion to vSphere 4.1 environments.
  • Convert the source machine to an ESX host running a lower version of ESX and then migrate the machine.
For more information, see the vCenter Converter 4.2 Standalone Release Notes.

Memory retention Failure, unflushed cach lost on IBM Server using ServeRAID-8k

This week we encountered this critical error on our IBM Server using ServeRAID-8K. The Server rebooted and since this server was hosting our VM, several of our VM was disconnected.

Power-cycling didn't help. Bu thanks God there is one cool writeup by a system administration that encounter the same problem. His description of the problem of the ServeRAID-8K and how he tried to fix it is nicely documented.
 Tuesday Outage: It’s RAID-tastic!

To resolve the issues, we just update the RAID-8K firmware. See IBM ServeRAID-8i, 8k, 8k-l and 8s BIOS and firmware update CD v5.2.0 (Build 16002) - IBM BladeCenter and System x

After upgrading the firmware, the problem was fixed!

Using Gnome Partition Editor (Gparted) to resize, move the partition Windows NTFS

GParted is a free partition editor for graphically managing your disk partitions. The latest stable version of GParted is able to handle comfortably the following file systems. See Gpart -- Features. Please check before you use Gparted.

I have used the Gparted to shrink my D drive, and expand the "C" Drive on a Windows 7. I was pleasantly surprised that after dhrinking my D drive, I can move "D" Drive to the "free space" and  create "free" space on the right of the C Drive. And all this is done with simple clicked, drag and drop.

Indeed a wonderful tool for System Administration
