Adding additional hard disk to Windows 2003 server

[chill]

ESX3 server with Windows 2003 virtual server - trying to add 50 gig of hard disk space, but after I add it - the virtual server cannot find the operating system. As soon as I remove it, the server boots up fine. The new space is set up as Hard Disk 2. Any ideas?

When adding the disk, what's the virtual device node assigned to the new disk? The boot drive should be 0:0 (assigned automatically) and subsequent drives should be 0:1, 0:2, etc.

It sounds like (but I may be wrong) you're trying to increase the capacity of the disk with the OS installed on. I assume using vmkfstools -x?

If so you need so use a winPE boot disc, I use BartPE, with disk partition tools included.

Then select ‘Go | System | Storage | Disk part’.

Using the command line, select the correct Disk and partition. Use the expand command then list the volumes to make sure it has picked up the new size.

Power-up the VM and wait for it to confirm the new hardware device and restart when it prompts.

OS disk is now the new size.

If I've got the wrong end of the stick here just ignore the above :smileywink:

Thanks, I missed that part. Silliness on my part. Thanks for your help.
