Resolving voltage and temperature warnings
1. Check that all of the fans are working by making sure the Voltage/Fan Fault/Service Required LED on
each power supply is off, or by using the SMU to check enclosure health status. In the Configuration
View panel, right-click the enclosure and select View > Overview to view the health status of the
enclosure and its components. The Enclosure Overview page enables you to see information about
each enclosure and its physical components in front, rear, and tabular views—using graphical or
tabular presentation—allowing you to view the health status of the enclosure and its components.
See
"Options available for performing basic steps" (page 45) for a description of health status icons
and alternatives for monitoring enclosure health.
2. Make sure that all modules are fully seated in their slots with latches locked.
3. Make sure that no slots are left open for more than two minutes.
If you need to replace a module, leave the old module in place until you have the replacement or use a
blank module to fill the slot. Leaving a slot open negatively affects the airflow and can cause the
enclosure to overheat.

• In the SMU, review event logs for indicators of a specific fault in
a replication data path component. Follow any Recommended
Actions.
• In the Configuration View panel in the SMU, right-click the
secondary volume, and select View > Overview to display the
Replication Volume Overview table:
• Check for replication interruption (suspended) status.
• Check for inconsistent status.
• Check for offline status.
• Replications that enter the suspended state must be resumed
manually.

No Nonexistent replication image. • In the Configuration View panel in the SMU, expand vdisks and
their volumes to reveal the existence of a replication image or
images.
• If a replication image has not been successfully created, use the
SMU to create one as described in the “Using Remote Snap to
replicate volumes” topic within the SMU Guide.
