Hi all

So I embarked on the simple task of upgrading my ESXi server.

Followed the upgrade as per this procedure, no hiccups.

http://blog.vmpros.nl/2011/07/13/vmware-easy-upgrade-esxi-4-1-to-esxi-5-0/

Now when I boot my server it says it cannot boot from C:, no system disk, etc etc.

About to try reinstalling ESXi5 now but any ideas?

Did you install or upgrade a USB flash drive?

or was ESXi 4.1 on the system disk?

Personally, I would not try an upgrade, I would re-install from scratch. If you have VMs on ESXi 4.1, backup, install new, and restore VMs.

ESXi 4.1 was installed on the system disk.

If I choose "Install ESXi 5.0.0, PRESERVE VMFS" does that mean all I need to do is reconfigure the IP address etc of the Host, but VM's will be ok?

Correct, it will not upgrade the VMFS.

But personally, I would not do in place upgrades.

I meant re-trying the upgrade. It completes successfully (upgrade VMWare, preserve VMFS"

but on reboot it complains of no system disk.

So my best course of action is to now:

1. boot from vmware 5 disk
2. choose second option "Install ESXi 5.0.0, PRESERVE VMFS"
3. Hopefully that works and I can just reconfigure the IP

All should be fine after?

Upgrade is buggy, Complete a new installation.

Grub has not been installed on the active system disk.

When you say complete a new installation, you mean my post containing 3 steps?

I cannot format the whole disk and start completely fresh, my VM's are on there and now I have no way of getting them off!

1. Backup VMs
2. Complete a new installation, overwrite everything.
3. Restore VMs.

Do you have a copy of your VMs?

Well, you'll be in a mess now because of a failed install.

Install to a ESXi 5.0 to a USB flash drive or SD card.

or install ESXi 4.0 to a USB flash drive, and it will pickup the existing VMFS, Backup VMs, and then proceed with ihstalling to hard drives.

Personally I would always recommend installing ESXi to a USB flash drive or SD card.

Ok.

Something is up with this server I think!

Changed USB slot and it still wouldnt boot. Powered off completely, rebooted and its now booting to ESXi 5.0 from USB key.

Assign IP and away I go?
