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.

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.
