Installation guide

Automatically
Start This
Service
autostart If enabled, this virtual machine is started automatically after the
cluster forms a quorum. If this parameter is disabled, this virtual
machine is not started automatically after the cluster forms a
quorum; the virtual machine is put into the disabled state.
Run Exclusive excl usi ve If enabled, this virtual machine can only be relocated to run on
another node exclusively; that is, to run on a node that has no
other virtual machines running on it. If no nodes are available
for a virtual machine to run exclusively, the virtual machine is not
restarted after a failure. Additionally, other virtual machines do
not automatically relocate to a node running this virtual machine
as Run exclusive. You can override this option by manual
start or relocate operations.
Failover
Domain
d o mai n Defines lists of cluster members to try in the event that a virtual
machine fails.
Recovery
Policy
recovery Recovery policy provides the following options:
Disable — Disables the virtual machine if it fails.
Relocate — Tries to restart the virtual machine in another
node; that is, it does not try to restart in the current node.
Restart — Tries to restart the virtual machine locally (in the
current node) before trying to relocate (default) to virtual
machine to another node.
Restart-Disable — The service will be restarted in place if
it fails. However, if restarting the service fails the service will
be disabled instead of moved to another host in the cluster.
Restart
Options
max_restart
s,
restart_exp
i re_ti me
With Rest art or Rest art - Disab le selected as the recovery
policy for a service, specifies the maximum number of restart
failures before relocating or disabling the service and specifies
the length of time in seconds after which to forget a restart.
Migration Type mi g rate Specifies a migration type of live or pause. The default setting
is live.
Migration
Mapping
mi g rati o n_m
apping
Specifies an alternate interface for migration. You can specify
this when, for example, the network address used for virtual
machine migration on a node differs from the address of the
node used for cluster communication.
Specifying the following indicates that when you migrate a
virtual machine from member to member2, you actually migrate to
targ et2. Similarly, when you migrate from member2 to member,
you migrate using targ et.
member: targ et,member2: targ et2
