Managing Serviceguard Nineteenth Edition, Reprinted June 2011

vg
Specifies an LVM volume group (one per vg, each on a new line) on which a file system needs to
be mounted. A corresponding vgchange_cmd (page 235) specifies how the volume group is to
be activated. The package script generates the necessary file system commands on the basis of
the fs_ parameters (page 238).
NOTE: A volume group must be configured into the cluster (via the VOLUME_GROUP parameter)
before you can configure it into a modular package. For more information about cluster parameters,
see “Cluster Configuration Parameters ” (page 105).
cvm_dg
Specifies a CVM disk group (one per cvm_dg, each on a new line) used by this package. CVM
disk groups must be specified whether file systems need to be mounted on them or not. A
corresponding cvm_activation_cmd (page 235) specifies how the disk group is to be activated.
Any package using a CVM disk group must declare a dependency (see the entries for
dependency_name and related parameters starting on (page 227)) on the CVM system multi-node
package. See “Preparing the Cluster for Use with CVM ” (page 209).
vxvm_dg
Specifies a VxVM disk group (one per vxvm_dg, each on a new line) on which a file system needs
to be mounted. See the comments in the package configuration file, and “Creating the Storage
Infrastructure and file systems with LVM, VxVM and CVM” (page 168), for more information.
vxvm_dg_retry
Specifies whether to retry the import of a VxVM disk group, using vxdisk scandisks to check
for any missing disks that might have caused the import to fail. Equivalent to VXVM_DG_RETRY in
the legacy package control script.
Legal values are yes and no. yes means vxdisk scandisks will be run in the event of an
import failure. The default is no.
HP recommends setting this parameter to yes in Metrocluster installations using EMC SRDF.
IMPORTANT: vxdisk scandisks can take a long time in the case of a large IO subsystem.
deactivation_retry_count
Specifies how many times the package shutdown script will repeat an attempt to deactivate a
volume group (LVM) or disk group (VxVM, CVM) before failing.
Legal value is zero or any greater number. As of A.11.18, the default is 2.
kill_processes_accessing_raw_devices
Specifies whether or not to kill processes that are using raw devices (for example, database
applications) when the package shuts down. Default is no. See the comments in the package
configuration file for more information.
File system parameters
A package can activate one or more storage groups on startup, and mount logical volumes to file
systems. At halt time, the package script unmounts the file systems and deactivates each storage
group. All storage groups must be accessible on each target node. (CVM disk groups must be
accessible on all nodes in the cluster).
For each local file system you specify in the package configuration file (fs_name (page 238)), you
must identify a logical volume, the mount point, the mount, umount, and fsck options and type
of the file system; for example:
