This section provides the following procedures for removing or replacing a quorum device:
When a quorum device is removed, it no longer participates in the voting to establish quorum. Note that all two-node clusters require that at least one quorum device be configured. If this is the last quorum device on a cluster, clquorum(1CL) will fail to remove the device from the configuration. If you are removing a node, remove all quorum devices connected to the node.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.
# clquorum list -v
# clsetup

Answer the questions displayed during the removal process.
# clquorum list -v
Troubleshooting
If you lose communications between the cluster and the quorum server host while removing a quorum server quorum device, you must clean up stale configuration information about the quorum server host. For instructions on performing this cleanup, see Cleaning Up Stale Quorum Server Cluster Information.
This procedure removes the last quorum device from a two-node cluster by using the clquorum force option, –F. Generally, you should first remove the failed device and then add the replacement quorum device. If this is not the last quorum device in a two-node cluster, follow the steps in How to Remove a Quorum Device.
Adding a quorum device involves a node reconfiguration, which touches the failed quorum device and panics the machine. The Force option lets you remove the failed quorum device without panicking the machine. The clquorum command enables you to remove the device from the configuration. For more information, see the clquorum(1CL) man page. After you remove the failed quorum device, you can add a new device with the clquorum add command. See Adding a Quorum Device.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.
If the quorum device failed, use the –F Force option to remove the failed device.
# clquorum remove -F qd1
# clquorum list -v
See Adding a Quorum Device for instructions on adding the new quorum device.
# cluster set -p installmode=disabled
# cluster set -p installmode=disabled
This example shows how to put the cluster in maintenance mode and remove the last remaining quorum device in a cluster configuration.
Place the cluster in install mode # cluster set -p installmode=enabled Remove the quorum device # clquorum remove d3 Verify that the quorum device has been removed # clquorum list -v Quorum Type ------- ---- scphyshost-1 node scphyshost-2 node scphyshost-3 node
Use this procedure to replace an existing quorum device with another quorum device. You can replace a quorum device with a similar device type, such as replacing a NAS device with another NAS device, or you can replace the device with a dissimilar device, such as replacing a NAS device with a shared disk.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.
You need to first add a new quorum device to the configuration to take the place of the old device. See Adding a Quorum Device to add a new quorum device to the cluster.
See How to Remove a Quorum Device to remove the old quorum device from the configuration.
Refer to the hardware procedures in your hardware manual for your disk enclosure. See also the Oracle Solaris Cluster Hardware Administration Manual.
