Product Issues and Limitations
This section provides information on known issues and limitations for the HP Serviceguard
Storage Management Suite Version A.02.01.01 HP-UX 11i v3 bundles at the time of this release.
For the most recent information contact your HP support representative or the Hewlett-Packard
IT Resource Center.
Use of HP-UX mount Commands for CFS Environments
Once disk group and mount point multi-node packages are created with 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.
Any form of the HP-UX mount command (for example, mount -o cluster,
dbed_chkptmount, orsfrac_chkptmount) must not be used in an HP Serviceguard Storage
Management Suite with CFS environment. 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. Always use the CFS commands
cfsmount or cfsumount.
Guidelines for CFS Nested Mounts
A maximum of four levels of nesting is supported with CFS nested mounts. VxFS, Check Point
(ckpt), and snapshot cluster file systems are supported with CFS nested mounts. However, ckpt
and snapshot cluster file systems can only be mounted at the end of the nesting sequence, not
at the beginning or middle of the nesting sequence.
CFS admin scripts changes: With the nested mount point feature enabled, the only change in the
cfsmntadm add command interface is to specify a nested mount point in place of a normal
mount point. For example:
cfsmntadm add <shared_disk_group> <shared_volume> <mount_point>
[<package_name>] <node_name>= [<mount_options>]... is now changed to:
cfsmntadm add <shared_disk_group> <shared_volume>
<mount_point/nested_mount_point> [<package_name>] <node_name>=
[<mount_options>]...
