FAST.X needs to be configured on a VMAX3 array to access LUNs on an XtremIO X-Brick. In addition, existing data on the LUNs has to be preserved and made available for host access.
How can this be accomplished?
- A . By externally provisioning the LUNs
- B . By incorporating the LUNs
- C . By zoning the host HBAs to the VMAX3 array FE ports
- D . By zoning the host HBAs to the VMAX3 array DX ports
SRDF/A MSC has been configured between two sites. There are two VMAX3 arrays at the source site and two VMAX3 arrays at the target site. An SRDF/A MSC trip event has occurred.
