Setting up SnapMirror for baseline initialization, using multiple paths

To implement multiple paths between the source and destination storage system for baseline initialization, complete the following steps.

You can set up SnapMirror to use multiple paths at the outset. You can also convert a single path SnapMirror relationship to use multiple paths.

Ensure that you have two valid paths using the ping command from the source system to each of the IP addresses on the destination system.
Example
The IP addresses on the destination system are 10.10.10.24 and 10.10.11.24.
```
source> ping 10.10.10.24

10.10.10.24 is alive

source> ping 10.10.11.24

10.10.11.24 is alive
```
On the source system console, use the options snapmirror.access command to specify the host names of systems that are allowed to copy data directly from the source system.
Example
options snapmirror.access host=d_systemA
On the administration host, edit the snapmirror.conf file on the destination system to add an entry that defines the mode of the connection and what the two connections are. Following is the format of the entry.name = mode (src_system1,dest_system1) (src_system2,dest_system2)
where mode is either ‘multi’ or ‘failover’. See the na_snapmirror.conf(5) man page for details.
On the administration host, edit the /etc/snapmirror.conf file on the destination system to specify the volumes and qtrees to be copied and the schedule (minute hour day_of_month day_of_week or sync) on which the destination is updated. Use the connection name specified in Step 3 as the source system.
