MDM can be configured to run as "SINGLE" or "ONE" Serviceguard package OR as "MULTIPLE"
or "FOUR+ONE" Serviceguard packages.
In the case of a "SINGLE" package all MDM components (mdb mds mdis mdss) are always started
and stopped on the same cluster node which the Serviceguard package itself is started on. In this
case variable MDM_MGROUP_DEPEND will be used by the Serviceguard package called
(mgroupMDM) to start these in order.In the case of "MULTIPLE" Serviceguard packages each MDM
component (mdb or mds or mdis or mdss) is configured as a separate Serviceguard package
(mdbMDM mdsMDM mdisMDM mdssMDM) and can be started independent of the location of the
other MDM Serviceguard packages. Variable MDM_MASTER_DEPEND controls this configuration
and is used by a "FIFTH" Serviceguard package called (masterMDM) to start these in order.
The following table details the MDM_MGROUPand MDM_MASTER dependencies.
Table 32 MDM_MGROUP and MDM_MASTER dependencies
DescriptionDependency
The elements (mdb mds...) of variable MDM_MGROUP_DEPEND
are the names of the MDM components that are started from
MDM_MGROUP_DEPEND=" mdb mds mdis mdss”
a single Serviceguard package. The order of the MDM
components is important.
Each element (mdbMDM mdsMDM...) of variable
MDM_MASTER_DEPEND is the name of a Serviceguard

package to start. The position of the element determines the
start order.
