Volume Manager Initialization

You initialize the Volume Manager by using the vxinstall program. The vxinstall program places specified disks under Volume Manager control. By default, these disks are placed in the rootdg disk group. You must use the vxinstall program to initialize at least one disk into rootdg. You can then use the vxdiskadm interface or the Storage Administrator to initialize additional disks into other disk groups.

Once you have completed the package installation, follow these steps to initialize the Volume Manager.




	NOTE: Do not run vxinstall on HP-UX 11i Version 1.5 if you installed the default operating system, because VxVM initialization is done automatically when the default operating system is installed. If, however, you chose the VxFS whole disk option when you installed the operating system, then you will need to run vxinstall.

Create a disks.exclude file if you want to exclude disks from Volume Manager control. The vxinstall program ignores any disks listed in this file. Place this file in /etc/vx/disks.exclude.




	NOTE: The files `/etc/vx/cntrls.exclude` and `/etc/vx/disks.exclude` are used by the `vxinstall` and vxdiskadm utilities to automatically exclude controllers or disks so that these devices are not configured as Volume Manager devices. These files do not exclude controllers and disks from use by any other Volume Manager commands. See the `vxinstall`(1M) and `vxdiskadm`(1M) manual pages for more information.

Create a cntrls.exclude file if you want to exclude all disks on a controller from Volume Manager control. Place this file in /etc/vx/cntrls.exclude.
Start the vxinstall program by entering the following command:
# vxinstall

The vxinstall program then does the following:

examines and lists all controllers attached to the system
describes the installation process: Quick or Custom installation

Quick installation gives you the option of initializing all disks. If you wish to initialize only some of the disks for VxVM, use the custom installation process.

Custom installation allows you to control which disks are added to Volume Manager control and how they are added. You can initialize all disks on a controller or only the disks you plan on using.

For details on how to use the Quick or Custom installation option, see the VERITAS Volume Manager 3.1 for HP-UX Release Notes.
