HP Serviceguard Extended Distance Cluster for Linux A.12.00.00 Deployment Guide, March 2014

# vxvm_dg dg01
# vxvm_dg dg02
#
# NOTE: A package can have a mix of LVM volume groups and VxVM disk groups.
#
# NOTE: When VxVM is initialized it will store the hostname of the
local node in its volboot file in a variable called ‘hostid’.
The Serviceguard package control scripts use both
the hostname(1m) command and the VxVM hostid. This means you
must make sure that the VxVM hostid matches the output of the
hostname(1m) command.
If you modify the local host name after VxVM has been
initialized and such that hostname(1m) does not equal the
name returned by uname -n, you need to use the vxdctl(1m)
command to set the VxVM hostid field to the value of
hostname(1m). Failure to do so will result in the package
failing to start.

# Legal values for vxvm_dg: /^[0-9A-Za-z][0-9A-Za-z_.\-]*[0-9A-Za-z]$/, /^[0-9A-Za-z]$/.

#
# "fs_name", "fs_server", "fs_directory", "fs_mount_opt", "fs_umount_opt",
# "fs_fsck_opt", and# "fs_type" specify the filesystems which are used by
# this package.
#
# The "fs_type" parameter lets you specify the type of filesystem to be
# mounted. The legal values for file systems are 'ext2', 'ext3', 'ext4', 'xfs',
# 'vxfs' and 'btrfs'.
#
# The following section applies if the underlying file system is 'ext2',
# 'ext3', 'ext4', 'xfs', 'vxfs' or 'btrfs'.
#
# The filesystems are defined as entries specifying the logical
# volume, the mount point, the file system type, the mount,
# umount and fsck options.
#
# Each filesystem will be fsck'd prior to being mounted.
# The filesystems will be mounted in the order specified during package
# startup and will be unmounted in reverse order during package
# shutdown. Ensure that volume groups referenced by the logical volume
# definitions below are included in volume group definitions.
#
# Use the valid options supported by xfs in "fs_fsck_opt".
# Due to system crash, an xfs filesystem cannot be unmounted gracefully.
#
# NOTE: "fs_fsck_opt" can accept only those options that are supported
# with the corresponding filesystem, such as e2fsck for ext2, ext3, ext4,
# btrfsck for btrfs, xfs_repair for xfs.
#
# For example, if this package uses the following:
# logical volume: /dev/vg01/lvol1
# mount point: /pkg1a
# filesystem type: ext2
# mount options: read/write
#
# Then the following would be entered:
# fs_name /dev/vx/dsk/dg01/lvol1
# fs_server ""
# fs_directory /pkg04a
# fs_type "vxfs"
# fs_mount_opt ""
# fs_umount_opt ""
# fs_fsck_opt ""
Editing Parameters in the Configuration File
MD device parameters
Use the information on the Package Configuration worksheet to complete the file. You can also
refer to the comments in the configuration template for additional explanation of each parameter.
You can include the following information:
• xdc/xdc/rpo_target
This parameter specifies the Recovery Point Objective Target. This refers to the maximum time
window allowed after which the raid system will be disabled to prevent large data loss,
