56 Troubleshooting
Can you view information about remote links?
Can you create a replication set?
No Compatible firmware revision
supporting Remote Snap is not
running on each system used for
replication.
Perform the following actions on each system used for replication:
• In the Configuration View panel in the SMU, right-click the
system, and select Tools > Update Firmware.
The Update Firmware panel displays currently installed firmware
versions.
• If necessary, update the controller module firmware to ensure
compatibility with other systems.
No Invalid cabling connection.
(Check 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 on
the same fabric or network.
• Verify that cable connections are securely fastened.
• Inspect cables for damage and replace if necessary.

Answer Possible reasons Actions
Yes System functioning properly. No action required.
No Invalid login credentials • Verify user name with Manage role on remote system.
• Verify user’s password on remote system.
No Communication link is down. • Verify controller enclosure cabling (see Table 15 ).
• In the SMU, review event logs for indicators of a specific fault in
a host or replication data path component.
• Verify valid IP address of the network port on the remote system.
• In the Configuration View panel in the SMU, right-click the
remote system, and select Tools > Check Remote System Link.
Click Check Links.
Table 16 Diagnostics for replication setup: Viewing information about remote links
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 in
the SMU, 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 in the
SMU, 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 SMU topics “Using the Replication
Setup Wizard” or “Replicating a volume.”
