Your data service configuration might not be supported if you do not observe these restrictions.
Consider the restrictions in this section to plan the installation and configuration of Sun Cluster HA for DHCP. This section provides a list of software and hardware configuration restrictions that apply to Sun Cluster HA for DHCP only.
For restrictions that apply to all data services, see the Sun Cluster Release Notes.
The Sun Cluster HA for DHCP data service can only be configured as a failover service – DHCP cannot operate as a scalable service and therefore the Sun Cluster HA for DHCP data service can only be configured to run as a failover service.
DHCP server – DHCP has to operate as a DHCP server and not as a relay host.
DHCP single instance – Only one DHCP resource can be configured within Sun Cluster.
DHCP network table – The DHCP network table can be text or binary files and can be mounted as either a Failover File System (FFS) or a Global File System (GFS).
It is considered best practice when mounting Global File Systems to mount them with the /global prefix and to mount Failover File Systems with the /local prefix. However, be aware that this is simply viewed as best practice.
