vmware partition table lost while upgrading hdd, please help!

I have ibm x3550 M3 server that was running vmware 4.0. I had 2x140GB SAS disks in RAID1 and 2x300GB SAS disks in RAID1 as well. vmware esxi 4 was installe on 2x140gb sas raid.

i was upgrading from 2x140GB SAS to 2x600GB SAS. before upgrade i did a backup only of 2x140gb datastore.

when i removed 2x140gb disks and inserted 2x600gb and created additional virtual drive in ibm bios, i think ibm controller deleted a partition table on my 2x300gb disks


so without knowing that i installed esxi 5.0 latest version on 2x600gb and booted up. sadly my old datastore was not here and format type for volume was unknown


To have some backup i removed from raid 1x300gb and then replaced back 2x600gb with 2x140gb, the same issue.



when doing fdisk in console, it said lost partition table



following http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1002281 i created a simple partition table but still i can not mount or see any data


Create the partition:
Press n and press Enter to create a new partition.
Press p and press Enter to select that this is a primary partition.
Press 1 and press Enter to make the first partition.
Press 128 and Enter to  align the partition to sector 128.
Press Enter again to retain the default value.
Change the partition to type fb (VMFS):
Press t and press Enter. Partition 1 is automatically selected.
Enter fb and press Enter.

Press w and press Enter to save.
Run vmkfstools -V and press Enter to discover the VMFS.  




here is current result of fdisk -l
