HP Serviceguard Storage Management Suite for VERITAS manual CFS Installation Issues, Legacy Style

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.
