1.Virtualisation - see in video create HOST group for new array in old vsp
Old array is virtualized behind the Exxx.
•Virtualizing in Ops Center: E-VOL will get LDEV ID assigned during GUI process
•Virtualizing with raidcom: must do separate command to map LDEV ID to E-VOL
2.Cut over-
- Shutdown hosts being migrated (for clusters with SR/PGR, must shutdown before virtualization)
- Remove zones to source array ports
- Add zones to target array ports
- Boot up servers and verify virtualized LUNs present
- Verify multipathing, file systems and Apps/DB
