Monitor RAID performance and statistics on VMware ESXi 4.0

I have a client running a HP ML350 server with a E200i controller, with a raid 5 made of 3 500gb sata disks.  There is 1 2003 SBS server and 5 windows xp hosts running on the box.  

We've replaced the drives from time to time, and they seem to take a long time to rebuild, and the network appears slower during that process.   Today I was called because of slowness, and upon looking at the lights on the drives, they may be rebuilding.  I have no way to check unless I shutdown all the guests and reboot the server, and that is amajor inconvenience to the customer.  My question is:

How can I monitor the status of the RAID on a ML350 running vmware ESXi.   On a physical server I can install the HP tools to do so, but I dont belive I can do this on a virtual box, as the ESXi runs in-between the hardware and the windows guest.

Have you installed the HP OEM version of ESXi 4.0?

if not you will need to install the additional CIM providers, or you will need to BOOT from the Smart Start CDROM and select the Array Configuration Utility.

RAID 5 Rebuild times, with SATA disks can take a while.

Also, you can check the REBUILD Priority on the Array Controller, High, Medium or Low.

What Generation of HP ML350?

G3 does not seem to have OEM CIM providers for ESXi 4.0, its possible G3 is not on the Hardware Compatibility List.

So your options are to use Smart Start CDROM. ACU.

Ok.  "Offline Bundle"...  I install this on the host in maintenence mode, right?  This doesnt look like something I do with the Vsphere client, or the host update utility either.  It also looks like I may have to upgrade the host to 4.0 update 3 for it to work.  I am a windows guy, so can you give me any hints or point me to any other info that might be helpful?

Could I DOWNLOAD the HP ESXi, boot the CD and run it?  Would it upgrade the host for me, or would I lose my existing data store and all guests?

What is teh vihost update utility and how do i get it?

Yes, you would need to be at al least ESXi 4.0 U3.

The vihostupdate.pl utility is part of the vCLI

Download here

and follow the instructions inluded with the HP Offline Bundle.
