Creating volumes and volume configurations automatically using the metassist command requires that you have a functional Solaris Volume Manager configuration. Before you begin, you should have the following:
Superuser access, or be able to assume an equivalent role-based access control (RBAC) role. See Becoming Superuser (root) or Assuming a Role in System Administration Guide: Basic Administration for more information.
State database replicas, distributed appropriately for your system. See About the Solaris Volume Manager State Database and Replicas for more information about state database replicas.
Available disks for creating volumes. The metassist command uses disk sets to help manage storage. Completely unused disks (or an existing disk set) must be available to create new volumes using the metassist command. See Determining Which Disks Are Available for Top-Down Volume Creation for more information about disk availability.
In addition to these minimum requirements, do not disable the Solaris Volume Manager RPC daemons (rpc.metad, rpc.metamhd, and rpc.metamedd) in the /etc/inetd.conf file. These daemons are configured to start by default. They must remain enabled to allow Solaris Volume Manager to use shared disk sets.
