Enabling SnapMirror

SnapMirror enabling procedures

Before any SnapMirror replication process can begin, the SnapMirror feature must be licensed and enabled on the storage system.

Note
In addition to a SnapMirror license, a special license key is required to enable the synchronous SnapMirror feature. See Synchronous SnapMirror for license codes and specific information.

Entering license codes

Enter the SnapMirror license code on the system that is to be the source and on the system that is to be the destination.

To enter the SnapMirror license code, complete the following step.

Step	Action
1	On the server, enter the following command: license add xxxxxxx xxxxxxx is the license code you purchased. This setting persists across reboots.

Turning SnapMirror on

To turn SnapMirror on, complete the following steps.

Step	Action
1	Enter the following command on both the source system and destination system to enable SnapMirror: options snapmirror.enable on Alternatively, you can still use the older command instead to turn SnapMirror on: snapmirror on This setting persists across reboots.
2	If you are using the snapmirror.access option to specify allowed destinations...	If you are using the /etc/snapmirror.allow file to specify allowed destinations...
On the source, enter the following command as a single line: options snapmirror.access host=[dest_system1,dest_ system2...] The default value for the `snapmirror.access` option is `legacy`, which lets the /etc/snapmirror.allow file define the access permissions. This option persists across reboots.	Add the name of each destination system, on its own line, to the /etc/snapmirror.allow file.
