If the cluster uses a quorum server, update the Quorum Server software on the quorum server before you update the cluster.
Perform all steps as the root role on the cluster and on the quorum server.
See Adding a Quorum Device in Administering an Oracle Solaris Cluster 4.4 Configuration.
If you add another quorum server as a temporary quorum device, the quorum server can run the same software version as the quorum server that you are updating, or it can run the 4.4 version of Quorum Server software.
phys-schost# clquorum remove quorum-server
quorumserver# clquorumserver show +
If the output shows any cluster is still served by the quorum server, unconfigure the quorum server from that cluster. Then repeat this step to confirm that the quorum server is no longer configured with any cluster.
quorumserver# clquorumserver stop +
quorumserver# pkg uninstall ha-cluster/*
By default, this directory is /var/scqsd.
