Experiment: 1) Rcopy enabled and VV synced VV exported only from 3Par1 for both servers -> IO ok. All paths (4) on each server is active. 2) VV exported from 3Par2 with the same LUN id, WWN's of VV - equal, Rcopy policy checked. Servers WWN's is different, zonning according brocade best practice, -> Scan for HW changes -> IO ok, All paths (8) on each server is active. 3) Switchover Rcopy group -> Scan for HW changes -> IO failed -> All paths (8) on each server is standby. 4) unexport VV from 3Par1 -> Scan for HW changes -> IO ok. All paths (4) on each server is active. |
