Creation of mapping for parallel data transfer by using IPV6 address and hostname

To enable parallel data transfer on IPV6, both home clusters nodes and cache cluster nodes must be running on IPV6. A Gateway Node that runs IPV6 must be able to communicate to the individual home export node to synchronize data across the clusters.

Mapping of home cluster nodes and gateway nodes at cache that are running on IPV6 can be mapped together either by using IPV6 address or the hostname.

Examples of creating mapping by using IPV6 address and hostname

Mapping creation by using IPV6 address

As you start creating mapping by using IPV6 addresses, IPv6 address must be written inside a square bracket '[ ]'.

The following example demonstrates how to create mapping by using IPV6 address:

mmafmconfig add map1 --export-map [2001:192::42f2:e9ff:feaf:6aa8]/[2001:192::42f2:e9ff:feaf:85a0],[2001:192::42f2:e9ff:feaf:6c30]/[2001:192::d756:f6d2:2710:330f]

System output:

mmafmconfig: Command successfully completed 
mmafmconfig: Propagating the cluster configuration data to all affected nodes
This is an asynchronous process.

Mapping creation by using hostname

Creation of mapping by using hostname is exactly similar to IPv4 mapping creation.
The following example demonstrates how to create mapping by using the hostname:
```
mmafmconfig add mapx1 --export-map c80f3m5n06/c80f2m5n02,c80f3m5n05/c80f5m5n14
```
System output:
```
mmafmconfig: Command successfully completed 
mmafmconfig: Propagating the cluster configuration data to all affected nodes
This is an asynchronous process.
```
In the preceding command example, c80f3m5n06 and c80f3m5n05 are export nodes at the home cluster and c80f2m5n02 and c80f5m5n14 are Gateway nodes at the cache cluster.

In the preceding examples, all the hostname resolution is pointing to the IPv6 address.

Note:

Mix of IPv6 and IPv4 mapping is not supported.

After the mapping is created, user can create an AFM fileset by using mapping. The following command demonstrates how a user can create an AFM fileset by using mapping:

mmcrfileset <FS> <fset_name> –p afmMode=<AFM Mode>,afmTarget=<protocol>://<Mapping>/<remoteFS_Path>/<Target> --inode-space new
