3PAR Remote Copy (RCIP) Basic Network Setup

Basic Network Setup for Remote Copy over IP on 3PAR

Setting up remote copy for 3PAR it`s easy and straight forward.
We are working on 8440 3PAR system, with 4 controller nodes.

Before doing any setup, your Remote Copy tab in CMC will look like in the picture bellow:

First, we need to connect to 3PAR CLI using administrator account:

Default credentials for 3PAR are:
Username: 3paradm
Password: 3pardata

Our systems have 4 RC ports, one on each node.

showport command will list all ports and their details:

If you execute showport -rcip comand you will get following answer:
DC13PAR cli% showport -rcip
There is no specified port information.

You need to setup IP details for each port as next step. Command for this task is:

controlport rcip addr <ip_address> <subnet_mask> <node:slot:port>

In our example:

DC13PAR cli% controlport rcip addr 10.244.77.200 255.255.255.192 0:3:1
Are you sure you want to change the address for 0:3:1?
select q=quit y=yes n=no: y
Remote Copy interface change successful.

Do the same for all interfaces (in our case, interfaces numbers are: 0:3:1, 1:3:1, 2:3:1 and 3:3:1) but don`t forget to change the IP address as each interface needs a different IP.

Execute startrcopy command to enable the RC engine.
DC13PAR cli% startrcopy

Now, if you run showport -rcip command you should get an output similar to:

DC13PAR cli% showport -rcip

Notice there is no gateway set up. We need to add Gw details for each port. Command is:

controlport rcip gw <ip_address> <node:slot:port>

In our case: 

DC13PAR cli% controlport rcip gw 10.244.77.193 0:3:1
Are you sure you want to change the gateway for 0:3:1?
select q=quit y=yes n=no: y
Remote Copy interface change successful.

Running  showport -rcip command you should be able to see all details:

RO_DC1_135_3PAR_SYS cli% showport -rcip
N:S:P State ---HwAddr---        IPAddr         Netmask       Gateway  MTU  Rate Duplex AutoNeg

Execute showrcopy command to check the status:

DC13PAR cli% showrcopy

Remote Copy System Information

Status: Started, Normal

At this point you should configure the secondary system similar to the primary one and test the connection between them.

Ping command to test the connection is:
controlport rcip ping <ip_addr> <node:slot:port>
