Oracle^® Solaris Cluster 4.3 System Administration Guide

How to Configure a Device Group on the Primary Cluster

Before You Begin

Ensure that you have completed the following tasks:

• Read the guidelines and requirements in the following sections:

  • Understanding Availability Suite Software in a Cluster

  • Guidelines for Configuring Host-Based Data Replication Between Clusters

• Set up the primary and secondary clusters as described in Connecting and Installing the Clusters.

1. Access nodeA by assuming the role that provides solaris.cluster.modify authorization.

   The node nodeA is the first node of the primary cluster. For a reminder of which node is nodeA, see Example Cluster Configuration.

2. Create a metaset to contain the NFS data and associated replication.

   nodeA# metaset -s nfsset a -h nodeA nodeB

3. Add disks to the metaset.

   nodeA# metaset -s nfsset -a /dev/did/dsk/d6 /dev/did/dsk/d7

4. Add mediators to the metaset.

   nodeA# metaset -s nfsset -a -m nodeA nodeB

5. Create the required volumes (or metadevices).

   Create two components of a mirror:

   nodeA# metainit -s nfsset d101 1 1 /dev/did/dsk/d6s2
   nodeA# metainit -s nfsset d102 1 1 /dev/did/dsk/d7s2

   Create the mirror with one of the components:

   nodeA# metainit -s nfsset d100 -m d101

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

   nodeA# metattach -s nfsset d100 d102

   Create soft partitions from the mirror, following these examples:

   • d200 - The NFS data (master volume):

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

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

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

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

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

   • d203 - The remote shadow bitmap volume:

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

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

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

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

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