Can you view information about remote links?
Can you create a replication set?
No Proper 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 SMU’s Configuration View panel, 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.
(If multiple storage systems are
used, 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
Answer Possible reasons Actions
Yes System functioning properly. No action required.
No Communication link is down. • Check cable connections and reseat if necessary.
• Inspect cable for damage.
• Swap cables to determine if fault is caused by a defective
cable; replace cable if necessary.
• In SMU, review event logs for indicators of a specific fault
in a host or replication data path component.
• In SMU’s Configuration View panel, right-click the remote
system, and select Tools > Check Remote System Link.
Click Check Links.
Answer Possible reasons Actions
Yes System functioning properly. No action required.
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.”
No Unable to select the primary
volume (the volume containing
the data to replicate)?
• In SMU’s Configuration View panel, expand vdisk entries
to show secondary volumes.
• In SMU, review event logs for indicators of a specific fault
in a host or replication data path component.
