The driver uses a special naming tag to know whether or not it owns a \"hidden\" parent volume, so it\u0027s completely safe to change and there are no upgrade issues.  \n\nThe original reason we defaulted this to False is because it uses extra array resources.  However, there are at least two features that are made needlessly complex (deletion and expansion) with that configuration, and it would probably be both unacceptable to users and difficult to work around (though possible).  So, it was deemed to be more important to default to True.\n\nWe\u0027re still working on getting the Zuul stuff working here, as you might have noticed with the -1 verified :)","commit_id":"ffb2eb23581c2263f16369d4f232d8ace0458ba0"},{"author":{"_account_id":38059,"name":"Anoop Kumar Shukla","display_name":"Anoop Shukla","email":"anoop.shukla@netapp.com","username":"anoop2","status":"NetApp"},"change_message_id":"d70df696ee4b4687cee9bb77ef5fe39ea7262689","unresolved":false,"context_lines":[{"line_number":129,"context_line":"        min\u003d1, max\u003d600,"},{"line_number":130,"context_line":"        help\u003d\u0027Interval in seconds to check asynchronous copying status during \u0027"},{"line_number":131,"context_line":"             \u0027a copy pair deletion or data restoration.\u0027),"},{"line_number":132,"context_line":"    cfg.BoolOpt("},{"line_number":133,"context_line":"        \u0027hitachi_manage_drs_volumes\u0027,"},{"line_number":134,"context_line":"        default\u003dTrue,"},{"line_number":135,"context_line":"        help\u003d\u0027If true, the driver will create a driver managed vClone parent \u0027"},{"line_number":136,"context_line":"             \u0027for each non-cloned DRS volume it creates.
