Tony, unisphere can manage arrays back to R19. Use a global domain and you should be able to see your pre R30 arrays. But there are restrictions on what can be done, due to flare constraints... ie. fast is not available on R26 and below and thin pools are not available on non CX4 arrays.  Jim
Hi,  We are going to upgrade our existing CX3 Storage Array to a CX4.  We believe that it will be running FLARE 30 and will be managed by Unisphere.  However, we also have another CX4 Storage Array (In our remote site) runs FLARE 29.   We would like to know can we manage both CX4 Storage Arrays with Unisphere OR we have to use separate tools (i.e. Navisphere Manager for FLARE 29 and Unisphere for FLARE 30).  Your advice is sought.  
Can unisphere manage CX4 Storage Array running FLARE 29 ?
