Mount Information

The /etc/vfstab file contains the mount points of file systems residing on local devices. For a multihost file system used for a logical host, all the nodes that can potentially master the logical host should possess the mount information.

The mount information for a logical host's file system is kept in a separate file on each node, named /etc/opt/SUNWcluster/conf/hanfs/vfstab.logicalhost. The format of this file is identical to the /etc/vfstab file for ease of maintenance, though not all fields are used.

You must keep the vfstab.logicalhost file consistent among all nodes of the cluster. Use the rcp command or file transfer protocol (FTP) to copy the file to the other nodes of the cluster. Alternatively, edit all of the files simultaneously by using crlogin or ctelnet.

The same file system cannot be mounted by more than one node at the same time, because a file system can be mounted only if the corresponding disk group has been imported by the node. The consistency and uniqueness of the disk group imports and logical host mastery is enforced by the cluster framework logical host reconfiguration sequence.
