HP Serviceguard A.11.20- Managing Serviceguard Twentieth Edition, August 2011

vgchange_cmd, and use the fs_ options in the FILESYSTEMS portion of the configuration
file to specify the options for mounting and unmounting the file systems. Do not use the vxvm_dg
or cvm_dg parameters for LVM volume groups. Enter each volume group on a separate line,
for example:
vg vg01
vg vg02
• If you are using CVM disk group for raw storage (without CFS), use cvm_dg parameters
(page 249) to specify the names of the disk groups to be activated, select the appropriate
cvm_activation_cmd, and create a dependency (page 238) on SG_CFS_pkg. See “Creating
the Storage Infrastructure with Veritas Cluster Volume Manager (CVM)” (page 219).
Do not use the vxvm_dg or vg parameters for CVM disk groups.
Do not include CFS-based disk groups in the package configuration file; they are activated
by the CFS multi-node packages before standard packages are started. See “Creating a
Storage Infrastructure with Veritas Cluster File System (CFS)” (page 199).
• If you are using VxVM disk groups without CVM, enter the names of VxVM disk groups that
will be imported using vxvm_dg parameters. See “How Control Scripts Manage VxVM Disk
Groups” (page 260).
• If you are using mirrored VxVM disks, use (page 248) to specify the mirror recovery option to
be used by vxvol.
• Specify the file system mount retry and unmount count options (see (page 250)).
• You can specify a deactivation_retry_count for LVM, CVM, and VxVM volume groups.
See (page 249).
• You can specify whether or not to kill processes activating raw devices on shutdown; see
(page 249).
• If your package uses a large number of volume groups or disk groups, or mounts a large
number of file systems, consider increasing the values of the following parameters:
◦ concurrent_vgchange_operations (page 247)
◦ concurrent_fsck_operations (page 250)
◦ concurrent_mount_and_umount_operations (page 250)
You can also use the fsck_opt and fs_umount_opt parameters (page 252) to specify the
-s option of the fsck and mount/umount commands.
• You can use the pev_ parameter (page 252) to specify a variable to be passed to external
scripts. Make sure the variable name begins with the upper-case or lower-case letters pev
and an underscore (_). You can specify more than one variable. See “About External Scripts”
(page 151), and the comments in the configuration file, for more details.
• If you want the package to run an external “pre-script” during startup and shutdown, use the
external_pre_script parameter (see (page 252)) to specify the full pathname of the script,
for example /etc/cmcluster/pkg1/pre_script1.
• If the package will run an external script, use the external_script parameter (see
(page 252)) to specify the full pathname of the script, for example /etc/cmcluster/pkg1/
script1.
See “About External Scripts” (page 151), and the comments in the configuration file, for more
information.
