4. Enter the controlport rcip ping command for each interface on each system in the
configuration.
NOTE: Because of the spanning tree protocol and MAC address learning, you might need
to ping each system several times before the server updates all tables and the ping succeeds.
Solution Problem
If the pings do not
succeed: 1. Issue another set of pings without specifying a size:
controlport rcip ping -pf <IP_address> <N:S:P>
If this ping command succeeds, the network does not support 9000-byte MTU.
2. Revert to 1500 MTU:
controlport rcip mtu 1500 <N:S:P>
3. Proceed to “Setting Up the Remote Copy Servers” (page 42) .
Setting Up Remote Copy over Fibre Channel
Configuring Ports for RCFC
For Remote Copy over Fibre Channel (RCFC) configurations, each link between a Remote Copy
pair is a physical link between a controller node on one storage system and a controller node on
the other storage system in the pair. These links use up to an 8 Gbps Fibre Channel adaptor port
from each of the two nodes in the storage systems that belong to the Remote Copy pair.
If these ports were not set up during the initial setup of the storage system, or if the configuration
has changed, reconfigure the ports before you set up the Remote Copy transport layer.
To configure the ports, use the controlport rcfc command.
CAUTION: Each pair of Remote Copy over Fiber Channel links must exist in an exclusive zone.
Fabric zones cannot be shared.
