In June 2013 the Oracle Solaris Cluster (OSC) Product Update Bulletin (Doc ID 1562168.1) included:

Storage Partner Update

EMC VPLEX

--

As always, all third-party storage vendors are responsible for qualifying and supporting
their products in an OSC environment and likely have both restrictions and requirements
which must be met in order for the configuration to be supported.

This document is to raise awareness for customers using OSC who plan to implement EMC VPLEX.

Symptoms

More and more customers are migrating to this product but doing so without proper consideration  or planning when used in an OSC environment. This has often left them with nodes that suffer Reservation Conflict (RC) panics and other related issues.

Changes

Migration to and/or implementation of EMC VPLEX.

Here is an example of a VPLEX lun:
