No. Server with solutions enabler dosn't require zoning to luns of ESX servers. You have to have a Server with lincenced installation of solutions enabler and with access to storage arrays (server must see gatekeepers or LUNZ). For normal discovery of clariions with solutions enabler yours server have to be zoned to clariion. If you don't want to zone it you should use assisted discovery. Next. You must perform a discover of Symmetrix and clariion arrays. You should be familar with SE CLI.
> C:\program files\emc\symcli\bin
symcfg discover (to discover symmetrix devices)
symcfg list (to list symmetrix devices and to check installation of SE)
symcfg authorization add -host <ip adress of clariion SPA> -username <username on SP> -password <password for user>
you should do that for every service procesor of clariion/s.
Next
symcfg discover -clariion
symcfg list -clariion (to list clariions)
Now you remote server with Solutions Enabler is ready to except connections from server with storage viewer.
