This is how we do it: we configure 2-node active/passive clusters ("rotating") with usually one service address and one or two RGs (i.e. DB, application). Each node has only 1 network adapter ("en0"):

- Create two NPIV-disks 1GB each and zoned to both nodes for the CAA-repositories (you need these instead of the heartbeat-disks).

- add the IPs and DNS-names for all cluster-nodes and all service-addresses to /etc/hosts and /etc/cluster/rhosts:

Code:

# cat /etc/hosts
10.1.1.1    node1
10.1.1.2    node2
10.1.1.3    service1

# cat /etc/cluster/rhosts
10.1.1.1
10.1.1.2
10.1.1.3

- switch off dead-gateway detection if applicable:

Code:

echo "!REQD en0 <default-gw>" > /usr/es/sbin/cluster/netmon.cf

- set PVid for Repo- and Spare-Disks:

Code:

root@node1 # chdev -a pv=yes -l hdisk<XX>
root@node1 # chdev -a pv=yes -l hdisk<YY>

root@node2 # cfgmgr

- start cluster-services:

Code:

root@node1/2 # startsrc -s clcomd
root@node1/2 # startsrc -s clinfoES

- create cluster itself (if that doesn't work restart the clcomd on both nodes like described below):

Code:

root@node1 # clmgr add cluster <CLUSTERNAME> \
             REPOSITORY=<hdiskXX> \
             NODES=<node1>,<node2>

root@node1/2 # stopsrc -s clcomd; sleep 2 ; startsrc -s clcomd

- First-alias distribution policy (needed for NIM to work on active cluster-node). You can do this only after defining the first cluster-network (see below)

Code:

root@node1 # clmgr mod network net_ether_01 RESOURCE_DIST_PREF=NOALI

- discover shared discs/VGs:

Code:

root@node1 # clmgr disco vg

----- So far the cluster itself, now the resource groups. Repeat the following for every RG:

- Service-IP-Label, network:

Code:

root@node1 # clmgr add service_ip <service-IP> NETWORK=net_ether_01

- create application controller (former "start-/stop-scripts"):

Code:

root@node1 # clmgr add application_controller <APP_CONTROLLER_NAME> \
                      STARTSCRIPT=</path/to/startscript> \
                      STOPSCRIPT=</path/to/stopscript>

- create resource group (the following is commented for your information, but you need to remove the comments to make the command work):

Code:

root@node1 # clmgr add rg <RG-name> \
                   NODES=<node1>,<node2>[,...] \    # nodes to serve the RG
                   STARTUP=OHN \                    # online on home node only
                   FALLOVER=FNPN \                  # fallover to the node of next priority
                   FALLBACK=NFB \                   # never fall back ("anti RG-ping-pong")
                   SERVICE_LABEL=<serviceIP> \
                   VOLUME_GROUP=<vg1>[,<vg2>,...] \
                   FORCED_VARYON=true \
                   FS_BEFORE_IPADDR=true \
                   APPLICATIONS=<APP_CONTROLLER_NAME>

- finally sync cluster (just for the nerves :-) )

Code:

root@node1 # clmgr sy cl fix=yes

- start cluster:

Code:

clmgr on node <node1>[,<node2>,...]

I hope this helps.
