Probing Algorithm and Functionality
This section contains the procedures you need to configure HA for DHCP.
Some procedures within this section require you to use certain Solaris Cluster commands. Refer to the relevant Solaris Cluster command man page for more information about these command and their parameters.
The HA for DHCP data service
Perform this procedure on one node of the cluster only.
This procedure assumes that you installed the data service packages during your initial Oracle Solaris Cluster installation.
If you did not install the HA for DHCP packages as part of your initial Oracle Solaris Cluster installation, go to How to Install the HA for DHCP Packages.
# clresourcetype register SUNW.HAStoragePlus # clresourcetype register SUNW.gds
# clresourcegroup create -n nodelist dhcp-resource-group
# clreslogicalhostname create -g dhcp-resource-group \ > -h logical-hostname \ > logical-hostname-resource
# clresource create -g dhcp-resource-group \ > -t SUNW.HAStoragePlus \ > -p Zpools=dhcp-zspool \ > dhcp-hastorage-resource
# clresource create -g dhcp-resource-group \ > -t SUNW.HAStoragePlus \ > -p FilesystemMountPoints=dhcp-filesystem-mountpoint \ > dhcp-hastorage-resource
# clresourcegroup enable -M dhcp-resource-group
Edit /opt/SUNWscdhc/util/dhcp_config and follow the comments within that file. After you have edited dhcp_config, you must register the resource.
# cd /opt/SUNWscdhc/util # vi dhcp_config # ./dhcp_register
The following example shows dhcp_config that has been edited for a two node cluster with IPMP. The entries for Sun Cluster Carrier-Grade Edition can be ignored.
