Steps to add a new filesystem to be managed.  Each QFS filesystem needs its own resource.

o Make the new filesystem (/u03 in this case)

o Take the resource groups offline.

# clrg offline qfs-scalmounts-rg
# clrg offline qfs-metadata-rg

o Make the changes in /etc/vfstab

o Create new resources for the new filesystem. 

# clrs create -g qfs-metadata-rg -t SUNW.qfs -p qfsfilesystem=/u03 new-resource-name
# clrs create -g qfs-scalmounts-rg -t SUNW.ScalMountPoint -p mountpointdir=/u03 \
  -p filesystemtype=s-qfs -p targetfilesystem=fsname \
  -p Resource_dependencies=resource-name-from-previous-command new-resource-name

o Bring the resource groups back online.

# clrg online qfs-metadata-rg
# clrg online qfs-scalmounts-rg

To remove a Node From the Cluster:

From the node to be removed, which is in noncluster
mode and has access:

host # clnode remove - Use this only if the node has access to the cluster

host # clnode evacuate nodename - Switch All Resource Groups and Device Groups Off of a Node
host # clinterconnect disable nodename:endpoint - Manage the Interconnect Interfaces

SHUTTING DOWN AND BOOTING A CLUSTER

To shut Down the Entire Cluster:

host # cluster shutdown

From one node:

host # clnode evacuate
host # shutdown – Shut Down a Single Node

To boot a Single Node from the OBP:

ok> boot

To reboot a Node Into Noncluster Mode from the OBP:

ok> boot -x
