There is no option to schedule this configuration from iDRAC. So this is scheduled outside iDRAC. Can you check Lifecycle Log and see whether this is executed remotely. You can look for login logs before this storage operations. 
Hi,Currently, I used Dell power edge r630.- raid controller: PERC H330 Mini (Embedded) with RAID 1 for 02 disks.- firmware version: 25.5.9.0001- driver version: 7.719.02.00 we got check consistency every 10:00 Saturday.I checked on controller, virtual disk but didn't find any setting to set schedule for check consistency. we have alert on our monitoring system while check consistency running. No issue on physical disks, controller, virtual disk. [IMAGE] can we disable this check consistency from iDrac?
