How can this impact to the nightly process be minimized?
Storage administrators for an EMC Symmetrix VMAX need to increase allocated storage for Microsoft Exchange LUNs without interrupting its operation. Performing a virtual LUN migration causes a critical nightly clone operation to run for hours instead of minutes. This impacts later dependent jobs, preventing production operations from completing.

How do you migrate RDM data located on a Symmetrix array?
You are planning a cold migration of a virtual machine from one VMFS datastore to another. VAAI hardware acceleration is enabled and both datastores are on the same EMC Symmetrix array.
The virtual machine has RDMs attached to it.
When you perform the cold migration, the virtual disks move to their new location. However, it appears that the RDMs have been converted into virtual disks.

Which course of action will resolve this issue?
A company has implemented Microsoft Exchange Server 2010 in an SRDF environment with replicas being taken at the disaster recovery (DR) site. During testing of this solution, they have failed over Exchange operations to the DR site. The Exchange mailbox server appears to come online, but user mailboxes are inaccessible. The Exchange Management Console shows all mailboxes marked with a small red “x” over the mailbox icons.
