HP Proliant Dl380P G8 Accidentally Removed Logical Drive

[AT1]

I have HP Proliant Dl380P G8 Server with 4 SAS 600 GB configured as Raid 5

I istalled new SAS Drive 600 GB on the server i opened ACU and found it as an unassigned Logical Drive created array for this new drive then I deleted the array

Unfortunatelly after deleting the new Logical drive. i found the original array with 4 SAS Drives Deleted as well !!!

I Rebooted my Server, I found the array again Configured as Raid 5 same configuration before it has been deleted, but inside ACU--> View Status and Alert for this logical Drive threre is one Alert. Code Number:786 "Background parity initialization is currently queued or in progress on Logical Drive 2 (1.6 TB, RAID 5). If background parity initialization is queued, it will start when I/O is performed on the drive. When background parity initialization completes, the performance of the logical drive will improve."

I Rebboted my server but there is No Operating System found ??

Is there any way to recover my System again ?

is it Possible after the Background parity initialization compeletes the all data recovered 

Please Help me as soon as Possible

Consider Background parity initialization = format.

The only way back is likely restoring the backup.
