Restrictions for Sun NAS Devices

A Sun NAS device must be connected to all nodes. A Sun NAS device is supported as a quorum device only in a two-node cluster. A Sun NAS device appears as a SCSI shared disk to the quorum subsystem. The iSCSI connection to the Sun NAS device is completely invisible to the quorum subsystem.

There is no fencing support for NFS-exported file systems from a NAS device when used in a non-global zone, including nodes of a zone cluster. Fencing support of NAS devices is only provided in global zones.
