How to Update Quorum Devices After Adding a Node to a Global Cluster
Ensure that you have completed installation of the Oracle Solaris Cluster software on the added node.
If you added a node to a global cluster, you must update the configuration information of the quorum devices regardless of whether you use shared disks, NAS devices, a quorum server, or a combination. To do this, you remove all quorum devices and update the global-devices namespace. You can optionally reconfigure any quorum devices that you still want to use. This update registers the new node with each quorum device, which can then recalculate its vote count based on the new number of nodes in the cluster.
Any newly configured SCSI quorum devices will be set to SCSI-3 reservations.
Example 3-4 Updating SCSI Quorum Devices After Adding a Node to a Two-Node Cluster
The following example identifies the original SCSI quorum device d2
, removes that quorum device, lists the available shared devices, updates the global-device namespace, configures d3
as a new SCSI quorum device, and verifies the new device.
phys-schost# clquorum list d2 phys-schost-1 phys-schost-2 phys-schost# clquorum remove d2 phys-schost# clquorum status … --- Quorum Votes by Device --- Device Name Present Possible Status ----------- ------- -------- ------ phys-schost# cldevice list -v DID Device Full Device Path ---------- ---------------- … d3 phys-schost-2:/dev/rdsk/c1t1d0 d3 phys-schost-1:/dev/rdsk/c1t1d0 … phys-schost# cldevice populate phys-schost# ps -ef - grep scgdevs phys-schost# clquorum add d3 phys-schost# clquorum list d3 phys-schost-1 phys-schost-2
