storagescope loses all access to storage systems and data

StorageScope stores 6 weeks (42 days) of daily historical data. So if the data is older than 6 weeks in daily metrics tables, it is gone now. However the daily data should be rolled up to weekly and monthly tables if you have trending service enabled during this time.

You should still have data in dimension and relationship tables like SRMArray, SRMHost, SRMArrayDevice, SRMDeviceAllocation. And you should have data in weekly and monthly tables like ArrayMetricsWeekly and ArrayMetricsMonthly.

Please do discovery and run ETL, you can still continue run StorageScope reports for current data and historical data for weekly and monthly.

Thank you for the reply SarahXu. I guess I don't know much about storagescope. I don't know how to "do discovery" and I don't know what ETL is to run it. I do know that when I've run storagescope in the past it knew something about our half dozen CX's and our 2 DMX's and our 3 Celerras. Now it seems to have no data of any kind and doesn't even know those systems exist. I don't know how to get it to recognize them.

Here's a little background on the product that will help you understand Sarah's comments.  StorageScope is part of the EMC ControlCenter (ECC) suite.  It's primary purpose is to expose capacity related information for reporting and analytics.  There is a separate user interface for EMC ControlCenter (the ControlCenter Console) that has many capabilities.  For the purposes of this discussion, the important capability is the ability to manage discovery policies.  ControlCenter interacts with the devices under management (hosts, arrays, switches) via process known as discovery where agents working on behalf of ControlCenter communicate with the devices in your data center and take the collected data (managed objects) and persist them into the ECC repository where information about those objects can be displayed on the ECC Console.  Policies about when data collection should be run against the devices in your data cetner (schedule) as well as which devices should be "discovered" are all defined by these policies.  The policies are managed in a section in the ECC Console UI.

StorageScope uses a common data warehousing technique called "ETL" to take the online discovery data in the ECC repository and migrate it to the StorageScope data warehouse called the StorageScope repository.  This ETL process, by default, runs once per day and it is only after ETL is run that data will be available in the StorageScope UI, which is different than the ECC Console.

I hope this helps...

Thank you both very much for the information. Sorry I didn't reply sooner. Part of what you told me I already knew. Some of it was new to me. I guess, at this point, I still don't know how to resolve my problem. I'll probably open a case with EMC after I re-read Sarah's comments. Thanks again!

A couple weeks after I reported this problem I discovered storagescope was working again. Don't know why. It just was.

Used it off and on for a couple weeks ... experimenting.

Yesterday, I discovered that in Storagescope Query Builder - Query Results it says Downloading data, please wait ... and it never finishes. There is an icon running at the top of the page ... some java stuff I suppose ... but it just never completes the download. I tried a reboot to no avail.

We would need to investigate the logs to find the root cause, could be db connection issue.

If you provide us with the logs in some shared location we could get back to you.

Or you could open a defect and that way we can get to it.

Thanks
