Any form of the mount command (for example, mount -o cluster,
dbed_chkptmount, or sfrac_chkptmount) other than cfsmount or
cfsumount in a HP Serviceguard Storage Management Suite
environment with CFS should be done with caution. These non-cfs
commands could cause conflicts with subsequent command operations on
the file system or Serviceguard packages. Use of these other forms of
mount will not create an appropriate multi-node package which means
that the cluster packages are not aware of the file system changes.
Also check the syslog file for information.
NOTE CFS is supported on some, but not all current releases of HP-UX. Check
the latest Release Notes for your version of Serviceguard for up-to-date
information (http://www.docs.hp.com -> High Availability - >
Serviceguard).
Problems with VxVM Disk Groups
This section describes some approaches to solving problems that may
occur with VxVM disk groups in a cluster environment. For most
problems, it is helpful to use the vxdg list command to display the disk
groups currently imported on a specific node. Also, you should consult
the package control script log files for messages associated with
importing and deporting disk groups on particular nodes.
Force Import and Deport After Node Failure
After certain failures, packages configured with VxVM disk groups will
fail to start, and the following error will be seen in the package log file:
vxdg: Error dg_01 may still be imported on ftsys9
ERROR: Function check_dg failed
