Managing HP Serviceguard for Linux, Sixth Edition, August 2006

Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4114
ACCESS CONTROL POLICIES
Specify three things for each policy: USER_NAME,
USER_HOST, and USER_ROLE. For Serviceguard
Manager, USER_HOST must be the name of the
Session node. Policies set in the configuration file of a
cluster and its packages must not be conflicting or
redundant. For more information, see “Username
Validation” on page 126.
Package Control Script Variables
The control script that accompanies each package must also be edited to
assign values to a set of variables. Set variables, or leave them unset, as
described below.
PATH Specify the path to be used by the script.
DATA_REP This parameter indicates whether the script is being
used in a remote data replication scheme. Do not set it
unless the remote data replication scheme you are
using requires. The default is “none.”
RAIDTAB Do not use this parameter; it is deprecated in
Serviceguard for Linux.
(If used,
RAIDTAB specifies the configuration file that
contains the names of the multiple device groups used
by the package for multiple links to a disk array.)
RAIDSTART and RAIDSTOP
Do not use this parameter; it is deprecated in
Serviceguard for Linux.(If used,
RAIDSTART and
RAIDSTOP specify the method of activation for md.)
VGCHANGE This variable specifies the LVM activation command
used by the script. Leave the default (VGCHANGE=
“vgchange -a y”) if you want volume groups activated
in the default mode.
Volume Groups (VG)
These parameters specify the names of LVM volume
groups that are activated by the package. In the
package control script file, this variables is an array:
VG[ ].
