Im looking to upgrade the existing Raid5 array on a few of our ML350 G5 server. only snag is that they are running ESXi 3,5 so cannot use the windows based  configuration tool.

Current setup is 3 x 146GB SAS drives in Raid 5 Configuration i would like to increase this to 8 drives still Raid 5 with Hot spare.

Im presuming i cannot do this with destroying the ESXi datastore or am i wrong?

regards

You can,

but you will be down for a while...

1) shutdown ESXi (because you don't have full ESX, you can't use ACU for Linux in console :-(
2) use ACU from Smart Start -> expand (when controller starts expanding you should restart and then boot your ESXi
3) then wait (i don't know perhaps 1 day is enough for expansion)
4) from RCLI expand VMFS volume (if you dont have RCLI -> download it from wmware)
****************************************************
case that you Can upgrading your array from 72 to 300 flawlessy...

you can create a new partition on the new array created from additional
space ( with fdisk )
use "vmkpcidivy -q vmhba_devs" to know real devices name
in the array change the type of the partition to "FB" (Vmfs type ) ( still
with FDISK )

Then use vmkfstools -C ( uppercase ) to create the Vmfs filesystem example
Vmkfstools -C vmfs2 vmhbaX:Y:Z:PART

And you can use the -Z switch to extend a existing VMFS partition to another
Partition

a Possible solution, I Have built another ESXi Server as temorary store for the guest operating system whilst i recreate the Array from scratch but everytime i try to migrate the guest using virtuakl centre  to the other esx server its gets all the way to 99% and then times out. This was my favoured route as it mean minimal down time. Anythought on what could be causing that, i have tried rebooting both hosts to no avail.
