PERC 6i and VMWare ESXi

Hi Krishnaprasad,
 I ended up opening a ticket with VMWare. What happened is as
follows. For some reason the PERC controller was truncating the
true drive size by about 30 or so GB. I am not sure if this
occurred recently, or it has always been like this and it finally
got to a point where it functionally damaged the partition table.
Anyhow, per the VMWare support rep, I disconnected both drives from
the PERC controller, connected one of them to the onboard Cerc2/s
controller(in ATA mode), and proceeded to boot from that one drive.
The Cerc controller detected the correct drive size/geometry, and
from there, the support rep repaired the partition table and I was
able to dump my VM's to another disk. I wiped the partition
information from both drives via DD and deleted the virtual disk.
Now, when I go back to recreate the virtual disk, the drive size
reported by the PERC controller is wrong, it is reporting 609620MB
as opposed to 6400000. Hence my post last night...
