Managing Serviceguard Seventeenth Edition, First Reprint December 2009

See “Creating a Storage Infrastructure with Veritas Cluster File System (CFS)”
(page 237).
• 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 294).
• If you are using mirrored VxVM disks, use (page 280) to specify the mirror recovery
option to be used by vxvol.
• Specify the filesystem mount retry and unmount count options (see (page 283)).
• You can specify a deactivation_retry_count for LVM, CVM, and VxVM volume
groups. See (page 281).
• You can specify whether or not to kill processes activating raw devices on
shutdown; see (page 282).
• 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 279)
— concurrent_fsck_operations (page 282)
— concurrent_mount_and_umount_operations (page 282)
You can also use the fsck_opt and fs_umount_opt parameters (page 284) to specify
the -s option of the fsck and mount/umount commands.
• You can use the pev_ parameter (page 284) 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 186), 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 285)) 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 285)) to specify the full pathname of the script, for example /etc/
cmcluster/pkg1/script1.
See “About External Scripts” (page 186), and the comments in the configuration
file, for more information.
• To coordinate the startup and shutdown of database software with cluster node
startup and shutdown, you can use the database template files provided with the
separately purchasable Enterprise Cluster Master Toolkit product.
These files are in /opt/cmcluster/toolkit/DB/. Separate toolkits are available
for Oracle, Informix, and Sybase.
