peer persistence convert to 3DC PP

[dennischen]

Hi,

I met a problem in the PP converting to 3DC-PP. Three 3par systems are OS 3.3.1. A and B are currently running as peer persistence. When Adding the third storage C (cabling and zoning), the rcopy link A->C, B->C are alway down.

A:

3par_A cli% showrctransport -rcfc

N:S:P Peer_Node_WWN    Peer_Port_WWN    State

2:0:2 2FF70002AC021FA9 21020002AC021FA9 new 

3:0:2 2FF70002AC021FA9 20010002AC021FA9 new 

1:0:2 2FF70002AC01D245 21020002AC01D245 ready               #This is current pp rcopy link

0:0:2 2FF70002AC01D245 20020002AC01D245 ready             #This is current pp rcopy link

 B:

3par_B cli% showrctransport -rcfc

N:S:P Peer_Node_WWN    Peer_Port_WWN    State

3:0:2 2FF70002AC021FA9 23010002AC021FA9 new 

2:0:2 2FF70002AC021FA9 22020002AC021FA9 new 

1:0:2 2FF70002AC01D226 21020002AC01D226 ready              #This is current pp rcopy link

0:0:2 2FF70002AC01D226 20020002AC01D226 ready            #This is current pp rcopy link

 C:

3par_C cli% showrctransport

N:S:P Peer_Address     Address          State Type

3:0:1 23020002AC01D245 23010002AC021FA9 new   rcfc

2:0:2 22020002AC01D245 22020002AC021FA9 new   rcfc

1:0:2 22020002AC01D226 21020002AC021FA9 new   rcfc

0:0:1 23020002AC01D226 20010002AC021FA9 new   rcfc

 From "showrctransport -rcfc", the new added rcfc links are new, not the ready status. So I do the "creatercopytarget" to establish the rc link. Do the "creatercopytarget" in A/B/C.

A: creatercopytarget 3par_C FC 2FF70002AC021FA9 2:0:2: 21020002AC021FA9 3:0:2: 20010002AC021FA9

C: creatercopytarget 3Par_A FC 2FF70002AC01D226 0:0:1:23020002AC01D226 1:0:2: 22020002AC01D226

the B &C ......

But when showrcopy links, the new rcopy links are all down. What should I do next? Thanks for the advice!

3par_A cli% showrcopy links
