Sun Cluster 3.1 - 3.2 With Network-Attached Storage Devices Manual for Solaris OS

Restrictions for Network Appliance NAS Devices

When configuring a Network Appliance NAS device as a quorum device, you can only add the quorum device when all cluster nodes are operating and communicating with the Network Appliance NAS device.

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 Network Appliance NAS devices is only provided in global zones.
