This is a short overview on how to configure a zone cluster on Solaris Cluster 4.0. This is a little bit different as in Solaris Cluster 3.2/3.3 because Solaris Cluster 4.0 is only running on Solaris 11. The name of the zone cluster must be unique throughout the global Solaris Cluster and must be configured on a global Solaris Cluster. Please read all the requirements for zone cluster in Solaris Cluster Software Installation Guide for SC4.0.
For Solaris Cluster 3.2/3.3 please refer to my previous blog Configuration steps to create a zone cluster in Solaris Cluster 3.2/3.3.

• Check if zone cluster can be created
  # cluster show-netprops
  to change number of zone clusters use
  # cluster set-netprops -p num_zoneclusters=12
  Note: 12 zone clusters is the default, values can be customized!


• Create config file (zc1config) for zone cluster setup e.g:
  


• Configure zone cluster
  # clzc configure -f zc1config zc1
  Note: If not using the config file the configuration can also be done manually # clzc configure zc1


• Check zone configuration
  # clzc export zc1


• Verify zone cluster
  # clzc verify zc1
  Note: The following message is a notice and comes up on several clzc commands
  Waiting for zone verify commands to complete on all the nodes of the zone cluster "zc1"...


• Install the zone cluster
  # clzc install zc1
  Note: Monitor the consoles of the global zone to see how the install proceed! (The output is different on the nodes) It's very important that all global cluster nodes have installed the same set of ha-cluster packages!


• Boot the zone cluster
  # clzc boot zc1


• Login into non-global-zones of zone cluster zc1 on all nodes and finish Solaris installation.
  # zlogin -C zc1


• Check status of zone cluster
  # clzc status zc1


• Login into non-global-zones of zone cluster zc1 and configure the shell environment for root (for PATH: /usr/cluster/bin, for MANPATH: /usr/cluster/man)
  # zlogin -C zc1


• If using additional name service configure /etc/nsswitch.conf of zone cluster non-global zones.
  hosts: cluster files
  netmasks: cluster files


• Configure /etc/inet/hosts of the zone cluster zones
  Enter all the logical hosts of non-global zones

• Create a resource group in zone cluster
  # clrg create -n <zone-hostname-node1>,<zone-hostname-node2> app-rg
  Note1: Use command # cluster status for zone cluster resource group overview.
  Note2: You can also run all commands for zone cluster in global cluster by adding the option -Z to the command. e.g:
  # clrg create -Z zc1 -n <zone-hostname-node1>,<zone-hostname-node2> app-rg


• Set up the logical host resource for zone cluster
  In the global zone do:
  # clzc configure zc1
  clzc:zc1> add net
  clzc:zc1:net> set address=<zone-logicalhost-ip>
  clzc:zc1:net> end
  clzc:zc1> commit
  clzc:zc1> exit
  Note: Check that logical host is in /etc/hosts file
  In zone cluster do:
  # clrslh create -g app-rg -h <zone-logicalhost> <zone-logicalhost>-rs


• Set up storage resource for zone cluster
  Register HAStoragePlus
  # clrt register SUNW.HAStoragePlus
  
  Example1) ZFS storage pool
  In the global zone do:
  Configure zpool eg: # zpool create <zdata> mirror cXtXdX cXtXdX
  and
  # clzc configure zc1
  clzc:zc1> add dataset
  clzc:zc1:dataset> set name=zdata
  clzc:zc1:dataset> end
  clzc:zc1> verify
  clzc:zc1> commit
  clzc:zc1> exit
  Check setup with # clzc show -v zc1
  In the zone cluster do:
  # clrs create -g app-rg -t SUNW.HAStoragePlus -p zpools=zdata app-hasp-rs
  
  Example2) HA filesystem
  In the global zone do:
  Configure SVM diskset and SVM devices.
  and
  # clzc configure zc1
  clzc:zc1> add fs
  clzc:zc1:fs> set dir=/data
  clzc:zc1:fs> set special=/dev/md/datads/dsk/d0
  clzc:zc1:fs> set raw=/dev/md/datads/rdsk/d0
  clzc:zc1:fs> set type=ufs
  clzc:zc1:fs> add options [logging]
  clzc:zc1:fs> end
  clzc:zc1> verify
  clzc:zc1> commit
  clzc:zc1> exit
  Check setup with # clzc show -v zc1
  In the zone cluster do:
  # clrs create -g app-rg -t SUNW.HAStoragePlus -p FilesystemMountPoints=/data app-hasp-rs
  
  Example3) Global filesystem as loopback file system
  In the global zone configure global filesystem and it to /etc/vfstab on all global nodes e.g.:
  /dev/md/datads/dsk/d0 /dev/md/datads/dsk/d0 /global/fs ufs 2 yes global,logging
  and
  # clzc configure zc1
  clzc:zc1> add fs
  clzc:zc1:fs> set dir=/zone/fs (zc-lofs-mountpoint)
  clzc:zc1:fs> set special=/global/fs (globalcluster-mountpoint)
  clzc:zc1:fs> set type=lofs
  clzc:zc1:fs> end
  clzc:zc1> verify
  clzc:zc1> commit
  clzc:zc1> exit
  Check setup with # clzc show -v zc1
  In the zone cluster do: (Create scalable rg if not already done)
  # clrg create -p desired_primaries=2 -p maximum_primaries=2 app-scal-rg
  # clrs create -g app-scal-rg -t SUNW.HAStoragePlus -p FilesystemMountPoints=/zone/fs hasp-rs
  More details of adding storage available in the Installation Guide for zone cluster


• Switch resource group and resources online in the zone cluster
  # clrg online -eM app-rg
  # clrg online -eM app-scal-rg


• Test: Switch of the resource group in the zone cluster
  # clrg switch -n zonehost2 app-rg
  # clrg switch -n zonehost2 app-scal-rg


• Add supported dataservice to zone cluster
  Documentation for SC4.0 is available here




Example output:



Appendix: To delete a zone cluster do:
# clrg delete -Z zc1 -F +
Note: Zone cluster uninstall can only be done if all resource groups are removed in the zone cluster. The command 'clrg delete -F +' can be used in zone cluster to delete the resource groups recursively.
# clzc halt zc1
# clzc uninstall zc1
Note: If clzc command is not successful to uninstall the zone, then run 'zoneadm -z zc1 uninstall -F' on the nodes where zc1 is configured
# clzc delete zc1
