Isolating Remote Snap replication faults 55
Replication setup and verification
After storage systems and hosts are cabled for replication, you can use the Replication Setup Wizard in the
SMU to prepare to use the Remote Snap feature. Optionally, you can use telnet to access the IP address of
the controller module and access the Remote Snap feature using the CLI.
NOTE: Refer to the following manuals for more information on replication setup:
• See HP Remote Snap technical white paper for replication best practices
• See HP MSA 1040 SMU Reference Guide for procedures to setup and manage replications
• See HP MSA 1040 CLI Reference Guide for replication commands and syntax
• See HP MSA Event Descriptions Reference Guide for replication event reporting
Basic information for enabling the MSA 1040 controller enclosures for replication supplements the
troubleshooting procedures that follow:
• Familiarize yourself with Remote Snap by reviewing the “Getting started” and “Using Remote Snap to
replicate volumes” chapters in the SMU Reference Guide.
• For best practices concerning replication-related tasks, see the technical white paper.
• Use Wizards > Replication Setup Wizard to prepare to replicate an existing volume to another vdisk in
the secondary system.
Follow the wizard to select the primary volume, replication mode, and secondary volume, and to
confirm your replication settings. The wizard verifies the communication links between the primary and
secondary systems. Once setup is successfully completed, you can initiate replication from the SMU or
the CLI.
• For descriptions of replication-related events, see the Event Descriptions Reference Guide.
Diagnostic steps for replication setup
