HP Serviceguard manual Vg vg01 Vg vg02

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 -soption 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.
