Managing Serviceguard A.11.20, March 2013

• If the package needs to mount LVM volumes to file systems, use the vg parameters (page 252)
to specify the names of the volume groups to be activated, select the appropriate
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 252) to specify the names of the disk groups to be activated, select the appropriate
cvm_activation_cmd, and create a dependency (page 242) on SG_CFS_pkg. See “Creating
the Storage Infrastructure with Veritas Cluster Volume Manager (CVM)” (page 224).
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 204).
• 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 264).
• If you are using mirrored VxVM disks, use (page 252) to specify the mirror recovery option to
be used by vxvol.
• Specify the file system mount retry and unmount count options (see (page 254)).
• You can specify a deactivation_retry_count for LVM, CVM, and VxVM volume groups.
See (page 253).
• You can specify whether or not to kill processes activating raw devices on shutdown; see
(page 253).
• 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 251)
◦ concurrent_fsck_operations (page 254)
◦ concurrent_mount_and_umount_operations (page 254)
You can also use the fsck_opt and fs_umount_opt parameters (page 256) to specify the
-s option of the fsck and mount/umount commands.
• You can use the pev_ parameter (page 256) 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 157), 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 256)) 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 256)) to specify the full pathname of the script, for example /etc/cmcluster/pkg1/
script1.
See “About External Scripts” (page 157), and the comments in the configuration file, for more
information.
