### How to Configure a Device Group on the Secondary Cluster

Before You Begin

Complete the procedure How to Configure a Device Group on the Primary Cluster.

1. Access `nodeC` by assuming the role that provides `solaris.cluster.modify` RBAC authorization.
2. Create a metaset to contain the NFS data and associated replication.

       nodeC# metaset -s nfsset a -h nodeC

3. Add disks to the metaset.

   In the example below, assume that the disk DID numbers are different.

       nodeC# metaset -s nfsset -a /dev/did/dsk/d3 /dev/did/dsk/d4

   Note - Mediators are not required on a single node cluster.

4. Create the required volumes (or metadevices).

   Create two components of a mirror:

       nodeC# metainit -s nfsset d101 1 1 /dev/did/dsk/d3s2
       nodeC# metainit -s nfsset d102 1 1 /dev/did/dsk/d4s2

   Create the mirror with one of the components:

       nodeC# metainit -s nfsset d100 -m d101

   Attach the other component to the mirror and allow it to synchronize:

       metattach -s nfsset d100 d102

   Create soft partitions from the mirror, following these examples:

   - d200 - The NFS data master volume:

         nodeC# metainit -s nfsset d200 -p d100 50G

   - d201 - The point-in-time copy volume for the NFS data:

         nodeC# metainit -s nfsset d201 -p d100 50G

   - d202 - The point-in-time bitmap volume:

         nodeC# metainit -s nfsset d202 -p d100 10M

   - d203 - The remote shadow bitmap volume:

         nodeC# metainit -s nfsset d203 -p d100 10M

   - d204 - The volume for the Solaris Cluster`SUNW.NFS` configuration information:

         nodeC# metainit -s nfsset d204 -p d100 100M

5. Create file systems for the NFS data and the configuration volume.

       nodeC# yes | newfs /dev/md/nfsset/rdsk/d200
       nodeC# yes | newfs /dev/md/nfsset/rdsk/d204
