Managing Serviceguard Seventeenth Edition, First Reprint December 2009
cleans up any side effects of the package's run or halt attempt. In this case the package
will be automatically restarted on any available alternate node for which it is configured.
Problems with Cluster File System (CFS)
NOTE: Check the Serviceguard/SGeRAC/SMS/Serviceguard Manager Plug-in Compatibility
and Feature Matrix and the latest Release Notes for your version of Serviceguard for
up-to-date information about support for CFS (http://www.docs.hp.com ->
High Availability -> Serviceguard).
If you have a system multi-node package for Veritas CFS, you may not be able to start
the cluster until SG-CFS-pkg starts. Check SG-CFS-pkg.log for errors.
You will have trouble running the cluster if there is a discrepancy between the CFS
cluster and the Serviceguard cluster. To check, use gabconfig -a.
The ports that must be up are:
1. a — llt, gab
2. b — vxfen
3. v w — cvm
4. f — cfs
You can also check the syslog file for information.
Use mount commands other than cfsmount or cfsumount command with caution
in an HP Serviceguard Storage Management Suite environment with CFS. Commands
such mount -o cluster, dbed_chkptmount, or sfrac_chkptmount could cause
conflicts with subsequent command operations on the file system or Serviceguard
packages. Non-CFS mount commands will not create an appropriate multi-node
package, with the result that the cluster packages are not aware of the file system
changes.
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,
logging an error such as the following in the package log file:
vxdg: Error dg_01 may still be imported on ftsys9
ERROR: Function check_dg failed
