Patrol read mode considerations
Patrol read identies disk errors to avoid disk failures, data loss, or corruption.
The Patrol Read does not run on a physical disk in the following circumstances:
• The physical disk is not included in a virtual disk or assigned as a hot spare.
• The physical disk is included in a virtual disk that is undergoing one of the following:
– A rebuild
– A reconguration or reconstruction
– A background initialization
– A check consistency
In addition, the Patrol Read operation suspends during heavy I/O activity and resumes when the I/O is complete.
NOTE: For more information on how often the Patrol Read operation runs when in auto mode, see the respective
controller documentation.
NOTE: Patrol read mode operations such as Start and Stop are not supported if there are no virtual disks available in the
controller. Though you can invoke the operations successfully using the iDRAC interfaces, the operations fail when the
associated job is started.
