Managing Serviceguard A.11.20, March 2013

vgchange_cmd
Specifies the method of activation for each HP-UX Logical Volume Manager (LVM) volume group
identified by a vg entry (see (page 252)). Replaces VGCHANGE which is still supported in the package
control script for legacy packages; see “Configuring a Legacy Package” (page 307).
The default is vgchange -a e.
The configuration file contains several other vgchange command variants; either uncomment one
of these and comment out the default, or use the default. For more information, see the explanations
in the configuration file, “LVM Planning ” (page 105), and “Creating the Storage Infrastructure and
file systems with LVM, VxVM and CVM” (page 181).
(For more information about LVM, see the Logical Volume Management volume of the HP-UX System
Administrator’s Guide under HP-UX 11i v3 at http://www.hp.com/go/hpux-core-docs.)
NOTE: A given package can use LVM volume groups, VxVM volume groups, CVM volume
groups, or any combination.
cvm_activation_cmd
Specifies the method of activation for Veritas Cluster Volume Manager (CVM) disk groups. The
default is
vxdg -g \${DiskGroup} set activation=readonly
The configuration file contains several other vxdg command variants; either uncomment one of
these and comment out the default, or use the default. For more information, see the explanations
in the configuration file, and the sections “CVM and VxVM Planning ” (page 107) and “Creating
the Storage Infrastructure with Veritas Cluster Volume Manager (CVM)” (page 224).
vxvol_cmd
Specifies the method of recovery for mirrored VxVM volumes. Replaces VXVOL, which is still
supported in the package control script for legacy packages; see “Configuring a Legacy Package”
(page 307).
If recovery is found to be necessary during package startup, by default the script will pause until
the recovery is complete. To change this behavior, comment out the line
vxvol_cmd "vxvol -g \${DiskGroup} startall"
in the configuration file, and uncomment the line
vxvol_cmd "vxvol -g \${DiskGroup} -o bg startall"
This allows package startup to continue while mirror re-synchronization is in progress.
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 252) 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 255).
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 114).
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 252) specifies how the disk group is to be activated.
