You must install the iSCSI license from NetApp.
You must configure an iSCSI LUN on the clustered filer for use as the quorum device.
You must configure the NetApp NAS unit to use NTP for synchronizing time.
At least one of the NTP servers selected for the clustered filer must be an NTP server for the Sun Cluster nodes.
When booting the cluster, always boot the NAS device before you boot the cluster nodes.
If you boot devices in the wrong order, your nodes cannot find the quorum device. If a node should fail in this situation, your cluster might be unable to remain in service. If a service disruption occurs, you must either reboot the entire cluster or remove the NetApp NAS quorum device and add it again.
A cluster can use a NAS device for only a single quorum device.
You can configure other shared storage if you need additional quorum devices. Additional clusters that use the same NAS device can use separate LUNs on that device as their quorum devices.
See the following Sun Cluster documentation for information about installing a NetApp NAS storage device in a Sun Cluster environment: Sun Cluster 3.1 - 3.2 With Network-Attached Storage Devices Manual for Solaris OS.
This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix A, Sun Cluster Object-Oriented Commands.
Make sure that all Sun Cluster nodes are online and can communicate with the NetApp clustered filer.
Become superuser or assume a role that provides solaris.cluster.modify RBAC authorization on any node of the cluster.
Start the clsetup utility.
The clsetup Main Menu is displayed.
Type the number that corresponds to the option for Quorum.
The Quorum Menu is displayed.
Type the number that corresponds to the option for adding a quorum device. Then type yes to confirm that you are adding a quorum device.
The clsetup utility asks what type of quorum device you want to add.
Type the number that corresponds to the option for a netapp_nas quorum device. Then type yes to confirm that you are adding a netapp_nas quorum device.
The clsetup utility asks you provide the name of the new quorum device.
Type the name of the quorum device you are adding.
The quorum device name can be any name you choose. The name is only used to process future administrative commands.
The clsetup utility asks you to provide the name of the filer for the new quorum device.
Type the name of the filer of the new quorum device.
This name is the network-accessible name or address of the filer.
The clsetup utility asks you to provide the LUN ID for the filer.
Type the ID of the quorum device LUN on the filer.
The clsetup utility asks if to the new quorum device should be added on the filer.
Type yes to continue adding the new quorum device.
If the new quorum device is added successfully, the clsetup utility displays a message to that effect.
Verify that the quorum device has been added.
# clquorum list -v
The following example shows the clquorum command generated by clsetup when it adds a NetApp NAS quorum device. The example also shows a verification step.
Become superuser or assume a role that provides solaris.cluster.modify RBAC authorization on any cluster node. [Start the clsetup utility:] # clsetup [Select Quorum>Add a quorum device] [Answer the questions when prompted.] [You will need the following information.] [Information: Example:] [Quorum Device Netapp_nas quorum device] [Name: qd1] [Filer: nas1.sun.com] [LUN ID: 0] [Verify that the clquorum command was completed successfully:] clquorum add -t netapp_nas -p filer=nas1.sun.com,-p lun_id=0 qd1 Command completed successfully. [Quit the clsetup Quorum Menu and Main Menu.] [Verify that the quorum device is added:] # clquorum list -v Quorums Type ------- ---- qd1 netapp_nas scphyshost-1 node scphyshost-2 node
