Lost Partition & can't initialize

I have a Clariion AX4-5F and I was having trouble copying & deleting files & folders. I was getting a lot of hard disk # 51 & NTFS #57 errors in my system event log so I rebooted the server. When it came back up the 2 SAN drives connected to the server were missing. I went into Disk Management and it said the drives need to be initialized. When I tried to initialize them with MBR format, I get the message 'The device is not ready' & "VDS fails to write boot code on a disk during clean operation. Error code: 80070015@02070008" in the system log. I guess all the data is gone, which is no big deal, I just want to get the drive space back onto a stable partition. I unassigned the luns in Navisphere, rescanned & they went away. I then assigned them, rescanned & they came back, but still can't initialize them. The two drives are 2TB & 1.6TB in size connected directly to the server with fiber running Windows Server 2008R2. All components are 'Normal' & connections are 'Active'. It's running Flare ver. 02.23.050.5.711.
