Isolating Remote Snap replication faults 57
Can you replicate a volume?
No Unable to select the replication
mode (Local or Remote)?
• In the SMU, review event logs 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 vdisk with sufficient
unused capacity.
• Remote Replication mode replicates to a secondary volume
residing in an independent storage system:
• Verify selection of valid remote vdisk.
• Verify selection of valid remote volume on the vdisk.
• 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 vdisk to which you will replicate
data from the primary volume)?
• In the SMU, 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 new volume on the vdisk
• Selection of replication-prepared volume
No Communication link is down. See actions described in "Can you view information about remote
links?" (page 56).
Answer Possible reasons Actions

Answer Possible reasons Actions
Yes System functioning properly. No action required.
No Remote Snap is not licensed on
each controller enclosure used for
replication.
See actions described in "Can you successfully use the Remote Snap
feature?" (page 55).
No Nonexistent replication set. • Determine existence of primary or secondary volumes.
• If a replication set has not been successfully created, use the
SMU Replication Setup Wizard to create one.
• In the SMU, review event logs for indicators of a specific fault in
a replication data path component. Follow any Recommended
Actions.
