Domain.com site has a large base of EMC Storage products installed. On-site EMC residents are responsible for day-to-day storage administration tasks. There have been numerous complaints recently from end users, saying that storage, on which they had live data, had been deallocated from systems without notification. All storage manipulation requests are currently sent to the EMC residents via email request, and are stored for reference purposes in case questions arise regarding it.

What needs to be done to avoid similar problems from occurring in the future?

A.
Advise Domain.com that the residents should have root access to all servers so that they can monitor system level device utilization.

B.
Establish a change review board to verify all storage manipulation requests.

C.
Stipulate that EMC residents will not perform storage deallocation activities.

D.
Monitor devices through performance manager for several days prior to implementing changes to ascertain whether or not they are actively being used.
