Seems like you’ve noticed the system interaction with Atmos is different than what you may have been exposed to in Centera. Why is that? In addition to being optimized for archiving or tiering workloads like those from EMC Cloud Tiering Appliance (CTA), Atmos is also optimized for transactional, primary storage workloads making it an integral component of an application stack rather than merely a tier of storage. Plus, given it’s inherent active/active distributed architecture the dependency on networking and off-system services means the potential risk of introducing downtime from an unplanned change is serious. Architecture changes such as those you’ve listed aren’t to be taken lightly and are some of the reasons why we encourage you to leverage EMC support staff when making them. Remember, one of the benefits of the maintenance agreement is the careful planning and assumption of responsibility EMC bears when making changes to a deployed system. In fact, the tasks you’ve listed are rarely, if ever performed, and instead, and are often made during initial architecture and installation discussions.
So, do all maintenance tasks require support cases? Definitely not and in the case of our new Sumatra v2.1 software (available from Powerlink) one of its themes is improved operational efficiency and system management and combined with the new dense disk system architecture, offer step-by-step instructional videos for certain CRUs (customer replaceable units). Both are examples of user-driven maintenance tasks.
For maintenance tasks prior to v2.1, if you can contact me with an email (either through this support forum or from our online sandbox portal http://atmosonline.com/contact) I’ll send you a copy of our operational run book white paper covering the best practices for system care, including event management integration with frameworks and service management applications such as EMC Smarts.
As for the open support requests I’ll defer to the support specialists for their direct instructions.
Hope this helps add some background.
