Managing Serviceguard Eighteenth Edition, September 2010
IMPORTANT: Volume groups for multi-node and system multi-node packages must
be activated in shared mode: vgchange -a s, which is only available if the add-on
product Serviceguard Extension for Real Application Cluster (SGeRAC) is installed.
(See the latest version of Using Serviceguard Extension for RAC at
www.hp.com/go/hpux-serviceguard-docs for more information.) Shared LVM
volume groups must not contain a file system.
(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 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 134) and “Creating the Storage Infrastructure with Veritas Cluster
Volume Manager (CVM)” (page 268).
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 375).
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 303) specifies how the
volume group is to be activated. The package script generates the necessary filesystem
commands on the basis of the fs_ parameters (page 307).
