Before changing the file system configuration, unmount the file system on all the nodes.

A partition that will be added to the GFS Shared File System must be a logical volume of a GDS shared class. Also, the GDS logical volume must be ACTIVE.

GDS logical volume should set up as follows.

• Set up the type of a disk class with which GDS logical volume belongs as shared.(Change GDS class attributes)
• Set all the nodes that share GFS Shared File System as the scope of the disk class to which logical volume belongs.(Change GDS class attributes)

For GDS disk class operations, see the applicable items under "Operation using Global Disk Services Management View" in the "PRIMECLUSTER Global Disk Services Configuration and Administration Guide (Solaris(TM) Operating System)".
