Can you create a replication set?
Answer Possible reasons Actions
Yes System functioning properly. No action required.
No Selected link type or port-to-link
connections are incorrect.
• Remote Replication mode: In the Configuration View panel,
right-click the remote system, and select Tools > Check
Remote System Link. Click Check Links to verify correct link
type and remote host port-to-link connections.
• Local Replication mode: In the Configuration View panel,
right-click the local system, and select Tools > Check Local
System Link. Click Check Links to verify correct link type
and local host port-to-link connections.
No On controller enclosures with iSCSI
host interface ports, replication set
creation fails due to use of CHAP.
If using CHAP (Challenge-Handshake Authentication Protocol),
configure it as described in the Storage Management Guide
topics “Using the Replication Setup Wizard” or “Replicating a
volume.”
No Unable to select the replication mode
(Local or Remote)?

• Review event logs (in the Configuration View panel,
right-click the system, and select View > Event Log) for
indicators of a specific fault in a host or replication data
path component. Follow any Recommended Actions.
• Local Replication mode replicates to a secondary volume
residing in the local storage system.
• Verify valid links.
On dual-controller systems, verify that A ports can
access B ports on the partner controller, and vice versa.
• Verify existence of either a replication-prepared volume
of the same size as the master volume, or a disk group
with sufficient unused capacity.
• Remote Replication mode replicates to a secondary volume
residing in an independent storage system:
• Verify selection of a valid remote disk group.
• Verify selection of valid remote volume on disk group.
• Verify valid IP address of remote system network port.
• Verify user name with Manage role on remote system.
• Verify user password on remote system.
NOTE: If the remote system has not been added, it
cannot be selected.
No Unable to select the secondary
volume (the destination volume on
the disk group to which you will
replicate data from the primary
volume)?
1
• Review event logs for indicators of a specific fault in a
replication data path component. Follow any
Recommended Actions.
• Verify valid specification of the secondary volume
according to either of the following criteria:
• Creation of the new volume on the disk group
• Selection of replication-prepared volume
No Communication link is down. See actions described in Can you view information about
remote links? on page 97.

After ensuring valid licensing, valid cabling connections, and network availability, create the replication set using
the Wizards > Replication Setup Wizard.
