Post subject:  Change rcip peer IP address?
Hi all,

New to the board!

In my current job, I inherited two 3PAR arrays doing rcopy vi rcip.

I know enough to manage the array, support, and create new vdisks, however a bit unclear on rcopy.

I have googled, but there is little out there.

Recently I had to change subnets which caused a change to IP addresses on the remote (target?)array.

showrctransport shows:

N:S:P Peer_Address Address State Type
2:6:1 192.168.3.221 192.168.24.188 missing rcip
3:6:1 192.168.3.222 192.168.24.245 missing rcip

I changed 192.168.3.221 to 192.168.52.221 and 192.168.3.222 to 192.168.52.222 on the remote array.

On the source array has do I change the peer address?

Yes, I can ping the remote array interface from the source via the ping command:
controlport rcip ping 192.168.52.221 2:6:1

Thanks for any guidance!

-John

Hi John. I recently had to do this myself and it was a nightmare to figure out but eventually with HP I got it squared away. Here are my notes that may help. I had to dismiss the link and readmit it.

Hope this helps.

/////////////////////////////////

Changing the IP address of a remote copy link

1 – Remove the existing Link
The remote target is the 3PAR on the other side. So running the command from the "A" 3PAR the remote target would be "B".
X:X:X is the port of the NIC used for the interface on the current 3PAR.

Dismissrcopy <remote_target> X:X:X:<Current_IP>

2 – Readmit the link with the new IP address

Admitrcopylink <remote_target> X:X:X:<New_IP>
