Deployment Guide

To initiate replication, use the replicate CLI command or in the PowerVault Manager Replications topic, select Action >
Replicate.
• Using the PowerVault Manager, monitor the storage system event logs for information about enclosure-related events, and to
determine any necessary recommended actions
NOTE: These steps are a general outline of the replication setup. Refer to the following manuals for more information
about replication setup:
• See the Dell EMC PowerVault ME4 Series Series Storage System Administrator’s Guide for procedures to set up and
manage replications.
• See the Dell EMC PowerVault ME4 Series Series Storage System CLI Guide for replication commands and syntax.
NOTE: Controller module firmware must be compatible on all systems that are used for replication.
Diagnostic steps for replication setup
The tables in the following section show menu navigation for virtual replication using the PowerVault Manager:
NOTE: SAS controller enclosures do not support replication.
Can you successfully use the replication feature?
Table 26. Diagnostics for replication setup: Using the replication feature
Answer Possible reasons Action
Yes System functioning properly No action required.
No Compatible firmware revision
supporting the replication feature
is not running on each system that
is used for replication.
Perform the following actions on each system used for virtual replication:
• On the System topic, select Action > Update Firmware. The Update
Firmware panel opens. The Update Controller Modules tab shows firmware
versions that are installed in each controller.
• If necessary, update the controller module firmware to ensure compatibility
with the other systems.
• See the topic about updating firmware in the Dell EMC PowerVault ME4
Series Storage System Administrator’s Guide for more information about
compatible firmware.
No Invalid cabling connection. (If
multiple enclosures are used,
check the cabling for each
system.)
Verify controller enclosure cabling:
• Verify use of proper cables.
• Verify proper cabling paths for host connections.
• Verify cabling paths between replication ports and switches are visible to one
another.
• Verify that cable connections are securely fastened.
• Inspect cables for damage and replace if necessary.
No A system does not have a pool
that is configured.
Configure each system to have a storage pool.
Can you create a replication set?
After valid cabling, and network availability, create a replication set by selecting Action > Create Replication Set from the Replications
topic.

Answer Possible reasons Action
Yes System functioning properly. No action required.
