Check Consistency
Does my controller support this feature? See Supported Features.
Use the Check Consistency task to verify the accuracy of the redundant
(parity) information. This task only applies to redundant virtual disks. When
necessary, the Check Consistency task rebuilds the redundant data. If the
virtual disk is in a Failed Redundancy state, running a check consistency may
be able to return the virtual disk to a Ready state.
NOTE: On the PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di controllers, the
controller firmware uses the rebuild rate setting to control the system resource
allocation for the Check Consistency task. For more information, see Set Rebuild
Rate.
Cancel Check Consistency
Does my controller support this feature? See Supported Features.
Use the Cancel Check Consistency task to stop a check consistency
operation that is in progress.
NOTE: On the CERC SATA1.5/6ch controllers, reconfiguring a concatenated virtual
disk to a RAID 1 may cause the virtual disk to be in Resynching state. Performing a
Pause Check Consistency or a Cancel Check Consistency on a virtual disk while it is
in Resynching state causes the virtual disk to be in a Failed Redundancy state. For
more information, see Considerations for Concatenated to RAID 1 Reconfiguration
on CERC SATA1.5/6ch Controllers.
Pause Check Consistency
Does my controller support this feature? See Supported Features.
Use the Pause Check Consistency task to pause a check consistency while it
is in progress.
NOTE: The Pause Check Consistency task updates the virtual disk State property to
Resynching Paused immediately. The Progress property may continue to increment
for up to three seconds. This time delay occurs because the polling task may take
up to three seconds to query the task information and update the display.
NOTE: On the CERC SATA1.5/6ch controllers, reconfiguring a concatenated virtual
disk to a RAID 1 may cause the virtual disk to be in Resynching state. Performing a
