Creating volumes and volume configurations automatically with the metassist command requires that you have a functional Solaris Volume Manager configuration before you begin. At a minimum, you should have the following:
root access or have assumed an equivalent 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 to use for the volumes you will create. The metassist command uses disk sets to help manage storage, so complete disks (or an existing disk set) must be available to create new volumes with the metassist command.
In addition to these minimum requirements, do not disable the disk set RPC daemons (rpc.metad, rpc.metamhd, and rpc.metamedd) in the /etc/inetd.conf file. These daemons are configured to start by default. and must remain enabled to allow Solaris Volume Manager to use its full functionality.
