Requirements When Configuring Sun NAS Devices

When you configure a Sun NAS device, you must meet the following requirements.

• Allow trusted administrative access for rsh.

  Sun Cluster uses rsh to log into the filer to run fencing. Sun Cluster automatically removes file system write permission for a node that has left the cluster, and grants file system write permission for a node that has just joined the cluster. These actions ensure that a node that departed the cluster can no longer modify data.

• Ensure that nodes in the cluster have trusted administrative access to the filer.

• Explicitly grant access to each node in the cluster.

  Do not allow general access to directories and do not add access by specifying a cluster host group.
