An EMC Symmetrix VMAX storage array is hosting multiple Microsoft Exchange 2010 servers in a virtualized infrastructure. Replication Manager is being used with TimeFinder/Clone to provide backups of the Microsoft Exchange 2010 environment with Microsoft Volume Shadow Service (VSS).
Each hypervisor has two HBAs which are zoned into separate fabrics with four FAs from the Symmetrix VMAX in each fabric. The hypervisors host four Exchange 2010 servers that contain 20 databases each. When presenting the RDMs to the hypervisors using Auto-Provisioning, some of the RDMs are not visible.
What could be the issue?

A.
Path to LUN per hypervisor limit of 1024 has been exceeded

B.
Hypervisor LUN limit of 256 has been exceeded

C.
ACLX database entries per FA limit has been exceeded

D.
Auto-Provisioning limits have been exceeded
