READ ME before using the Veritas Storage Foundation™ 5.1 SP1 Cluster File System Administrator's Guide (April 2011)

using the sg/cfs_all template. CVM must be up and running when you create or modify modular
CFS packages.
For more information on modular CFS packages, see Creating a Storage Infrastructure with Veritas
Cluster File System (CFS) and Managing Disk Groups and Mount Points Using Modular Packages
in chapter 5 of Managing Serviceguard Nineteenth Edition available at: www.hp.com/go/
hpux-serviceguard-docs → HP Serviceguard Storage Management Suite A.04.xx
NOTE: Serviceguard Manager can be used to create new modular CFS packages. For more
information on how to configure modular style CFS packages using the Serviceguard Manager
GUI, see the Serviceguard Manager online help.
NOTE: Serviceguard does not support online addition/removal operations for modular CFS
packages. Specifying services and resources is not recommended for modular CFS packages. You
cannot create or manage modular CFS packages for disk groups and mount points using the VEA
GUI, but you can use Serviceguard Manager to perform these tasks.
Legacy Style
The following CFS commands are used to create and configure legacy packages:
• cfscluster — cluster configuration command
• cfsmntadm — adds, deletes, modifies, and sets policy on cluster mounted file systems
• cfsdgadm — adds or deletes shared disk groups to/from a cluster configuration
• cfsmount/cfsumount — mounts/unmounts a cluster file system on a shared volume
IMPORTANT: Once disk group and mount point multi-node packages are created with HP
Serviceguard, it is critical to use the CFS commands, including cfsdgadm, cfsmntadm, cfsmount,
and cfsumount. If the HP-UX mount and umount commands are used, serious problems such
as writing to the local file system, instead of the cluster file system, could occur. You must not use
the HP-UX mount command to provide or remove access to a shared file system in a CFS
environment (for example, mount -ocluster, dbed_chkptmount, or sfrac_chkptmount).
These non-CFS commands could cause conflicts with subsequent CFS command operations on the
file system or the Serviceguard packages. Use of HP-UX mount commands will not create an
appropriate multi-node package, which means cluster packages will not be aware of file system
changes. Instead, use the CFS commands - cfsmount or cfsumount.
CFS Installation Issues
If you encounter any issues installing CFS, refer to the following paragraphs for typical problems
and their solutions. You can also refer to the HP Serviceguard Storage Management Suite Version
A.04.00 for HP-UX 11i v3 Release Notes, if you encounter an issue that is not included here.
Incorrect permissions for root on remote system
The permissions are inappropriate. Make sure you have remote root access permission on each
system to which you are installing.
Checking communication with system01............... FAILED
Remote reams/rcp permissions not available on: system01
Correct permissions and continue
Continue? [Y/N]:
Suggested solution: You need to set up the systems to allow remote access using ssh or rsh.
