Adhering to Quorum Device Requirements
Ensure that Oracle Solaris Cluster software supports your specific device as a quorum device. If you ignore this requirement, you might compromise your cluster's availability.
Note - For a list of the specific devices that Oracle Solaris Cluster software supports as quorum devices, contact your Oracle service provider.
Multi-hosted shared disks that support SCSI-3 PGR reservations.
Dual-hosted shared disks that support SCSI-2 or SCSI-3 PGR reservations.
A quorum server process that runs on the quorum server machine.
Any shared disk, provided that you have turned off fencing for this disk, and are therefore using software quorum. Software quorum is a protocol developed by Oracle that emulates a form of SCSI Persistent Group Reservations (PGR).
Caution - If you are using disks that do not support SCSI, such as Serial Advanced Technology Attachment (SATA) disks, turn off fencing.
Oracle ZFS Storage Appliance iSCSI quorum device.
Oracle Solaris Cluster software supports the following types of quorum devices:
Note - You cannot use a storage-based replicated device as a quorum device.
In a two–node configuration, you must configure at least one quorum device to ensure that a single node can continue if the other node fails. See Figure 3–2.
For examples of recommended quorum configurations, see Recommended Quorum Configurations.
