Also, if you encounter problems while installing GFS, you may need to delete a cluster.

The URLs listed here provide this information as well.

This chapter describes how to install GFS in the VTS environment.

Note Additional information about managing GFS is provided in the Maintaining GFS for

Installing GFS

If you want to install GFS for the first time, or if you want to reinstall GFS and remove all

volume data, complete all steps in the following procedure. If you want to reinstall GFS and

keep volume data from a previous installation, complete steps

12-19 starting on page 6.

Note If path failover is configured in the environment, be sure to reference the multipathed

reference /dev/mapper/mpathX instead of /dev/sdX.
