The SDS should only be installed in one zone on a system, either a global or non-global zone. The agent can be installed on any zone. The installer does not have to know on which zone it is installed.
If you are planning to install an agent in a non-global zone, an agent must also be installed in the global zone (CR 6511890)
Before determining where to install the agent, consider the following Solaris zone patching rules:
When an agent is installed in a sparse zone, it is not possible to install packages or patches which require updates to the /usr directory. This is because the /usr directory is designed to be read-only in a sparse zone and is shared with the global zone.
Some patches installed in the global zone will also affect the local zones.
