If the pings fail, issue another set of pings without specifying a size. If this second

attempt succeeds, the new setting is not supported and you should revert to 1500 MTU

3.4.3 Setting Up Remote Copy Over Fibre Channel

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 server and a controller node

on the other storage server in the pair. These physical links use up to a 4 Gbps Fibre Channel

adaptor port from each of the two nodes in the storage servers that belong to the Remote

Copy pair. Typically, these ports are configured during the initial setup of the storage system.

If the setup did not occur, or the configuration has changed, you will need to reconfigure the

ports before you can begin setting up Remote Copy. Ports are configured using the

controlport rcfc

command. See

Appendix B, Remote Copy Commands

for more

information on this command. See the InForm OS Command Line Interface Reference for

complete information on using this command.

RCFC requires a dedicated node pair per target. Each fibre channel interface on each node in

the primary InServ Storage Server must connect to a dedicated fibre channel interface on each

node in the backup InServ Storage Server. For example, in

Figure 3-5

:

Fibre channel interfaces on nodes 0 and 1 on the Primary InServ connect to fibre channel

interfaces on Backup InServ1 nodes 0 and 1, respectively.

Fibre channel interfaces on nodes 2 and 3 on the Primary InServ connect to fibre channel

interfaces on Backup InServ2 nodes 0 and 1, respectively.

CAUTION: Each pair of Remote Copy over Fiber Channel links must exist in an

exclusive zone. Fabric zones cannot be shared.
