DataStore Gone :( due to removing LUNs: pls help

Hi,

Pls see the below steps I did :

• I created two luns 850 GB & 76 GB on EMC CX300 and assigned it to ESX and expanded/increased the datastore
• Then I deleted those luns directly from Storage – EMC CX 300 (I did not removed the LUNs from the datastore) – I think this is the only thing which I missed and problem created.
• After seeing the ESX datastore again, it was grayed out and nothing was happening.
• When trying to take console of those VMs it was not letting me to see the OS window
• And when tried RDP it was going

Please help me to restore the datastore again to the normal state. I am worried about those 5 VMs (Servers) that I have build 6 months ago

I need to add 1 TB to the datastore but it is not functioning at all.

Please help me...

THanks,

Yash
