I just upgraded to ESXi 5, however there was no support for the JMicron ATA Controller on my EP45-UD3L board.
Vib can be installed into a running instance like so:
#set acceptance to community support if not already selected esxcli software acceptance set --level=CommunitySupported esxcli software vib install -v http://dustint.com/code/pata-jmicron-0.1.5.x86_64.vib
Note that I could not get the package to work with an existing instance and had to do a “fresh” install of ESXi (rather than installing the package or an in-place upgrade).

After upgrading to VMWare ESXi 5 from 4.1, I found one of my datastore volumes would no longer mount. The disk would show up as a device, but there were a series of errors whenever I tried to mount the volume.
After trying a variety of things, I still couldn’t get the volume to mount, so I decided to try to recover the virtual machines off the drive before wiping it.
The first step is to configure the un-mountable disk as a raw passthrough. This will allow a guest OS to access the disk. Instructions for these steps can be found here:
After converting the disk to a raw passthrough, assign it to a virtual machine on your ESXi host. I chose Gentoo Linux.
By default, most linux distributions don’t ship with VMFS support, however Christophe Fillot and Mike Hommey have developed a tool called vmfs-tools that allows mounting of VMFS partitions. If you have Debian or Ubuntu you can simply install the package. Since I was using Gentoo I had to build from source:
You may have to emerge some of the prerequisites if you do not have them. See the vmfs-tools site for details.
wget http://glandium.org/projects/vmfs-tools/vmfs-tools-0.2.1.tar.gz tar -xf vmfs-tools-0.2.1.tar.gz cd vmfs-tools-0.2.1 ./configure make && make install
Now that we have vmfs-fuse installed, we can mount our volume:
#Ensure the fuse kernel module is loaded modprobe fuse #Mount the device to the desired mountpoint vmfs-fuse /dev/sdd1 /mnt/vmfs #copy files off of mounted vmfs cp -Rv /mnt/vmfs /tmp
