The reason we don't support a scheduled refresh from within XtremIO is that a refresh will normally require more than just action on the array - it'll need you to do some stuff on the host first.  Before you refresh a snapshot you will need to make sure that nothing on the host has it mounted in any way. This isn't a requirement on the array side (the refresh will work regardless), but if the host is still using the device when it's refreshed (eg, the filesystem is still mounted, or Oracle ASM still has the diskgroup mounted, etc) then the host will see this as data corruption - as the data on the LUN changed without it's knowledge.  Thus a typical refresh operation (on any array, not just XtremIO) will look something like : * Stop any application using the LUNs being refreshed (eg, Oracle) * Unmount filesystems/diskgroups/etc using those LUNs * Refresh * Re-mount the diskgroups/filesystems/etc * Restart the application  If you want to schedule this there's really 2 options, either script it yourself (including all of the steps above in the script) with the refresh step being done using the XtremIO API, or use EMC AppSync which will handle most/all of it for you.  If you want to script it, [URL] would be a good place to start (especially the link at the very bottom to details on using the API).  If you want to look at AppSync talk to your EMC account team.  An AppSync Starter Bundle (up to 20 mounted copies - far more than enough for most people) is included free with XtremIO.
Hello Everyone:  The last week, we create an Consistency Group and a Snapshot set for him. The Snapshots volumes were presented to AIX Test  Server and customer could recognize the snapshot volumes in the OS and start up the Oracle DB.  Now, Customer is asking a refresh of the snapshot. In the last two days,  we did tests with the refresh option in the GUI for the Snapshot Set and everything worked so very well.  The only point, is that we don't see any option to schedule the refresh of the snapshot set .... I did a SR and the answer was "not possible schedule a refresh of snapshot", only possible by demand using the GUI.  We're requiring run the refresh every Sunday at 4:00 am. Somebody, can say me if there is any way to schedule the refresh by cron using CLI ? ... or any other method ??  Thank you in advance for your help.
