Operating System Software User Manual

• <N:S:P>—Location on the current system (System1) that contains the IP connections to
the target system, expressed as node:slot:port
• <link_IP_addr>—Link IP address for the corresponding port on the target system (for
example, XXX.XX.1.10 or XXX.XX.1.11).
For RCFC:
# creatercopytarget <target_name> FC <node_WWN> <N:S:P>:<WWN> <N:S:P>:<WWN>
where:
• <target_name>—Name of the target system (System2)
• FC—Defines link as an FC link
• <node_WWN>—WWN of the node on the target system
• <N:S:P:WWN>—FC adapter port on the primary system (System1), expressed as
node:slot:port, and the WWN of the peer port on the target system (System2)
NOTE: On each node, you can configure only one link per target definition.
SolutionProblem
If link performance is below standard, HP 3PAR Remote
Copy does not admit the link. For more information, see:
Before admitting a link to a target definition, HP 3PAR
Remote Copy checks its throughput and latency, which
may be inadequate.
“Checking RCIP Link Throughput and Latency” (page 33)
Setting Up the Backup System for M-to-N Remote Copy
When you set up the links on the backup storage system, you create the links in the opposite
direction.
1. Issue the following command to start HP 3PAR Remote Copy on the backup storage system
(System2):
# startrcopy
2. Issue the following command to define a target on the backup system (System2).
For RCIP:
# creatercopytarget <target_name> IP <N:S:P>:<link_IP_addr>
<N:S:P>:<link_IP_addr>
where:
• <target_name>—Name of the target system (System1)
• IP—Defines link as an IP link
• <N:S:P>—Location on the current system (System2) that contains the IP connections to
the target system, expressed as node:slot:port
• <link_IP_addr>—Link IP address for the corresponding port on the target system
(XXX.XX.1.10 or XXX.XX.1.11)
For RCFC:
# creatercopytarget <target_name> FC <node_WWN> <N:S:P:WWN> <N:S:P:WWN>
