Thanks Perry, for taking this up.

When I select Storage from the failover cluster I could see only 1 disk available with 900 GB in size and if I expand that disk I could see all the parttions but not able to map these partitions while configuring MSDTC . Please find the screenshot attached.

Please do let me know what should I do? Earlier I was using starwind for storage but this is the first time we are using SAN.
