Isolate Replication Faults
This procedure applies to following systems:
l
QXS-312 and QXS-324
l
QXS-412, QXS-324, QXS-448, and QXS-456
l
QXS-648 and QXS-656

Cabling for Replication
The replication feature is a licensed option for disaster recovery, providing access to either of the following
software product versions:
• V3 disk management utility supports replication for virtual storage environments.
• V2 disk management utility supports replication for linear storage environments.
These two replication models are mutually exclusive to one another. Choose the method that applies to your
storage system. For more information, see replication topics in the
QXS Disk Management Utility User
Guide V3
.
Replication setup and verification
After storage systems are cabled for replication, you can use the V3 or V2 disk management utility to
prepare to use the replication feature. Alternatively, you can use telnet to access the IP address of the
controller module and access the replication feature using the CLI.
Note:
You can use the CLI to perform replication in linear or virtual storage environments.
l
Set Management mode to v2 for linear replication (use Manage role).
l
Set Management mode to v3 for virtual replication (use Manage role).
Basic information for enabling the RAID chassis for replication supplements the troubleshooting procedures
that follow.
l
Familiarize yourself with replication by reviewing the “Getting started”, “Working in the Replications
topic”, and “the process to replicate volumes” chapters in the
QXS Disk Management Utility User Guide
V3
.
l
For virtual replication, in order to replicate an existing volume to a pool on the peer in the primary system
or secondary system, follow these steps:
l
Find the port address.
Using the CLI, run the query peer-connection command.
l
Create a peer connection.
