Troubleshooting
Replication setup and verification
After storage systems and hosts are cabled for replication, you can use the SMU to prepare to use the Remote Snap
feature. Optionally, you can use SSH 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 about replication setup:
•
See HPE Remote Snap
technical white paper for replication best practices
•
See
HPE MSA 2050 SMU Reference Guide
for procedures to setup and manage replications
•
See
HPE MSA 2050 CLI Reference Guide
for replication commands and syntax
•
See
HPE MSA Event Descriptions Reference Guide
for replication event reporting
Basic information for enabling the MSA 2050 SAN controller enclosures for replication supplements the troubleshooting
procedures that follow.
•
Familiarize yourself with replication content provided in the SMU Reference Guide.
•
For best practices concerning replication-related tasks, see the technical white paper.

In order to replicate an existing volume to a pool on the peer in the primary system or secondary system, follow these
steps:
Find the port address on the secondary system:
Using the CLI, run the
show ports
command on the secondary system.
Verify that ports on the secondary system can be reached from the primary system using either method below:
–
Run the
query peer-connection
CLI command on the primary system, using a port address obtained from
the output of the
show ports
command above.
–
In the SMU
Replications
topic, select
Action > Query Peer Connection
.
Create a peer connection.
To create a peer connection, use the
create peer-connection
CLI command or in the SMU
Replications
topic,
select
Action > Create Peer Connection
.
Create a replication set.
To create a replication set, use the
create replication-set
CLI command or in the SMU
Replications
topic,
select
Action > Create Replication Set
.
Replicate.
To initiate replication, use the
replicate
CLI command or in the SMU
Replications
topic, select
Action >
Replicate
.

Diagnostic steps for replication setup
The tables in this subsection show menu navigation for replication using the SMU.
IMPORTANT:
Remote Snap must be licensed on all systems configured for replication, and the controller module
firmware must be compatible on all systems licensed for replication.
